\mainpage Introduction

This manual explains the scope and the usage of the Software Pack for \b CMSIS-Driver \b Validation.
<a href="http://www.keil.com/pack/doc/CMSIS/Driver/html/index.html" target="_blank">CMSIS-Driver</a> specifies the 
software API for peripheral driver interfaces that connect microcontroller peripherals with middleware or the user application. 

The Software Pack for CMSIS-Driver validation provides:
  - Configurable validation tests for several CMSIS-Driver interfaces
  - Example projects that show the usage of the CMSIS-Driver validation

The CMSIS-Driver Validation tests and verifies:
  - \b API \b interface \b interaction using the driver capabilities as well as valid and invalid parameters.
  - \b Data \b communication with various transfer sizes and communication parameters (i.e. baudrate).
  - \b Loopback \b communication (for some interfaces) for testing the underlying hardware.
  - \b Transfer \b speed of the data communication with time measurement of data transfers.

The CMSIS-Driver Validation requires
<a href="http://www.keil.com/pack/doc/CMSIS/RTOS2/html/index.html" target="_blank">CMSIS-RTOS2</a> functionality and can be
used to verify the setup and configuration of the CMSIS-Driver interfaces in a user system. It is also used to validate
implementation of a CMSIS-Driver interface.

The diagram below is an overview of the configuration for CMSIS-Driver validation.

\page test_setup Test Setup

\section step1 Step 1: Create an MDK project with your target microcontroller device


\section step2 Step 2: Add required software components

For proper operation, add the following software components in the <b>Manage Run-Time Environment</b> window:
- <b>CMSIS Driver Validation:Framework</b>
- <b>CMSIS Driver Validation:driver</b>, driver interfaces to be tested
- <b>CMSIS Driver:driver</b>, driver implementations to be tested
- <b>CMSIS:RTOS2 (API):Keil RTX5</b>
- <b>Compiler:I/O:STDOUT</b>, variant \b ITM (if your hardware does not support ITM select \b User or \b EVR)
- Resolve any unresolved component dependecies


\section step3 Step 3: Add main.c

Right-click <b>Source Group 1...</b> and select <b>Add New Item to Group</b>. Select <b>User Code Template</b> and choose the
\b main file from <b>Device:Startup</b> or <b>CMSIS-RTOS2:Keil RTX5</b>.

Add this include:
\code
include "cmsis_dv.h"
\endcode

In the main function, after kernel initialization, create the \c cmsis_dv thread:
\code
osThreadNew(cmsis_dv, NULL, NULL);
\endcode
to run all tests that you have chosen in the next step.


\section step4 Step 4: Configure DV_Config.h

Open \c DV_Config.h under the <b>CMSIS Driver Validation</b> group in the Project window.

\image html dv_config_h.png "Configuration File DV_Config.h"

<b>Common Test Settings</b>

The common test settings help you to choose the output format of the test, buffer sizes and buffer content that should
be used for the send, receive, and transfer tests:
- The \b Print \b Output \b Format lets you select if you wish to create the output as plain text or as styled XML.
- \b Buffer \b sizes lets you select the buffer sizes that are used for data transfer. This setting has a direct impact on
  required \ref step6 "heap".
- You can specify also the <b>Buffer size for baudrate test</b>. For USART you can set the <b>Percentual tolerance for baudrate 
  test</b> and for SPI the <b>Percentual trigger for bus speed test</b>. Depending on the device \ref step7 "configuration", for 
  example when DMA is not used, the transfers may have larger overhead which is more significant for higher bus speeds. The 
  transfer overhead is reduced for larger transfer buffer sizes.
- Select your preferred <b>Buffer pattern</b>

<b>Driver-specific Settings</b>

Every interface has specific settings that can be changed in the according section:
- You need to specify the driver instance number (<b>Driver_<i>interface</i>#</b>) used for the test. This is especially
  important for microcontroller devices that have multiple peripherals of the same kind.
- Some drivers can have additional baudrate or timing settings.
- Select all driver tests that you wish to use. Note that all tests can run independently from each other. You do not need to
  specify a certain order.

\note For more information on additional settings and the different driver test cases, check the
<a class="el" href="./modules.html">Reference</a> section.
\note For WiFi driver validation some settings depend on the test environment and they need to be set properly, 
for details please refer to \ref wifi_config section.


\section step5 Step 5: Configure Keil RTX5

Open \b RTX_Config.h and set:
- <b>Default Thread stack size [bytes]</b> to \a 2048
- <b>Global Dynamic Memory size [bytes]</b> to \a 8192 (Note 1)

\note Note 1: This setting is only necessary for WiFi driver testing, for other tests default setting of 4096 is sufficient.

\section step6 Step 6: Configure Heap

Depending on the buffer sizes that you have chosen in \ref step4 "Step 4", you need to add more heap. Depending on how heap is 
configured in your system open your startup_<i>device</i>.s file from the \b Device group in the \b Project window or use a 
linker script to adjust the heap setting. Click on the 
<a href="http://www.keil.com/support/man/docs/uv4/uv4_ut_configwizard.htm" target="_blank">Configuration Wizard</a> view. 
Increase the heap size:
- for the validation framework add 1024 bytes.
- double the largest buffer size you have set in the configuration file and add this as well.

Refer to the \ref resource_requirements section for a calculation example.


\section step7 Step 7: Configure the Device

Depending on your device, you might have different pin/hardware configuration options. Usually, you can configure the device
using the \c RTE_Device.h file from the \b Device group. Enable all interfaces you wish to use in the tests and make all
necessary pin-out changes required by your actual board layout (consult the board schematics). The \ref examples "examples" 
are already configured for the underlying hardware.

For a robust test with good coverage, implement various targets with different settings:
- \b Enable/disable the \b DMA controller of your device
- Set different \b buffer \b sizes in \ref step4 "DV_Config.h"
- Select different compiler \b optimization \b levels in the
  <a href="http://www.keil.com/support/man/docs/uv4/uv4_dg_adscc.htm" target="_blank">C/C++ tab</a> of the
  <b>Options for Target</b> dialog.


\section step8 Step 8: Setup Additional Hardware

For the interfaces that support loopback testing: \ref eth_funcs "Ethernet", \ref spi_funcs "SPI", and \ref usart_funcs "USART", 
connect the following pins on your target hardware together (refer to the hardware schematics):

- Ethernet: RX+ and TX+, RX- and TX-
- SPI: MISO and MOSI
- USART: RX and TX

For WiFi specific hardware requirements please refer to \ref wifi_requirements.

\section step9 Step 9: Download and Run the Project

In the <b>Options for Target</b> dialog, under debug settings, if you use ITM as standard output channel ensure that 
\b Trace and ITM port \token{0} are enabled and that the correct clock frequency is set:

\image html target_dialog.png "ITM Channel setting"

Build, load and run the project. The output is displayed in the <b>Debug (printf) Viewer</b> window:

\endverbatim

The measured time is depending mainly on two factors: \b DMA and \b software \b overhead.

If you are not using \b DMA for data transfer, an interrupt is generated, in worst case, for every transferred byte. The
interrupt handling overhead for each byte can produce 10 times slower transfer than DMA. DMA will transfer the data
without overhead. Thus, only bus speed/baudrate tests with DMA enabled should be considered for
optimization. In case DMA cannot be used (because no DMA channel is left to be used for example), the user needs to be aware
that the data rates will decrease significantly.

The \b software \b overhead is introduced by the way the measurement is done. When the measurement is started a system tick 
value is stored and then the transfer is set up and started. The software then needs to determine when the transfer 
has ended and calculate required time difference by using previously stored system ticks and current system ticks.
Usually, the software overhead is a constant number of CPU cycles. The total amount of time required for the software overhead 
depends on the actual CPU that is used and on the optimization level used during build. \n
Increasing the <b>Buffer size for baudrate test</b> reduces the software overhead effect. The following calculation example
explains why.

\b Calculation \b Example

SPI bus speed = 25 Mbps

- Buffer size for baudrate tests = 512 byte (default value, equals 512 * 8 bit)
- Actual bus speed = 18 Mbps (read from driver)
- Expected time to transfer data = 227 µs (512 * 8 bit/18 Mbps)
- Measured time = 245 µs = 227 µs + 18 µs (coming from a software overhead)
- This results in a measured/expected time ratio of 1.08 which will lead to a warning

Using a buffer size of 8192 bytes in the example above will reduce the software overhead to less than 1% (which will issue no
warning anymore).

\section heap_req Heap Requirements
Heap is used by memory allocation functions. It is configured in the
<a class="el" href="http://www.keil.com/support/man/docs/gsac/gsac_startupcodecortex.htm" target="_blank">startup_device.s</a>
file located under the \b Device component class or by a linker script.

Additional memory is allocated for the validation framework and for the buffers that are used in the driver tests. 

For the validation framework add 1024 bytes of heap. Then, double the amount of the largest buffer size specified in the
\ref step4 "DV_Config.h" file and add this as well.

| Option (under section Heap Configuration)                         | Increase Value by
| :---------------------------------------------------------------- | :----------------------
| Heap Size (in Bytes)                                              | + (1024 + 2 x maximum buffer size)

\b Calculation \b Example

Let's assume that the default heap size in your device's startup file is \c 0x400 (which is 1024 bytes). Add 1024 for the
framework and for example another 2048 bytes if you are using the default \b Buffer \b Size of 512 bytes but you have set the
<b>Buffer size for baudrate tests</b> to 1024 bytes. This computes to a total heap of 3584 bytes which is equivalent to
\c 0xE00. Set this number in the startup file.


\section rtos2_req CMSIS-RTOS2 Requirements

The thread requirements need to be reflected in the CMSIS-RTOS2 configuration. Refer to the
<a class="el" href="http://www.keil.com/pack/doc/cmsis/RTOS2/html/index.html" target="_blank">CMSIS-RTOS2 Reference</a> for further details.

For <a class="el" href="http://www.keil.com/pack/doc/cmsis/RTOS2/html/rtx5_impl.html" target="_blank">CMSIS-RTOS2 RTX5</a>, thread
requirements are configured in the
<a class=el href="http://www.keil.com/pack/doc/cmsis/RTOS2/html/config_rtx5.html" target="_blank">RTX_Config.h</a> file located
under the \b CMSIS component class:

<table class="doxtable" summary="CMSIS-RTOS2 Configuration">
    <tr>
      <th align="left">Option (under section Thread Configuration)</th>
      <th>Set Value to</th>
    </tr>
    <tr>
      <td>Default Thread stack size [bytes]</td>
      <td>2048</td>
    </tr>
    <tr>
      <td>Global Dynamic Memory size [bytes] (Note 1)</td>
      <td>8192</td>
    </tr>
</table>

\note Note 1: This setting is only necessary for WiFi driver testing, for other tests default setting of 4096 is sufficient.
