5 This manual explains the scope and the usage of the Software Pack for \b CMSIS-Driver \b Validation.
6 <a href="http://www.keil.com/pack/doc/CMSIS/Driver/html/index.html" target="_blank">CMSIS-Driver</a> are standard peripheral
7 API interfaces that connect microcontroller peripherals with middleware or the user application.
9 The Software Pack for CMSIS-Driver validation provides:
10 - Configurable validation tests for several CMSIS-Driver interfaces
11 - Example projects that show the usage of the CMSIS-Driver validation
13 The CMSIS-Driver Validation tests and verifies:
14 - \b API \b interface \b interaction using the driver capabilities as well as valid and invalid parameters.
15 - \b Data \b communication with various transfer sizes and communication parameters (i.e. baudrate).
16 - \b Loopback \b communication (for some interfaces) for testing the underlying hardware.
17 - \b Transfer \b speed of the data communication with time measurement of data transfers.
19 The CMSIS-Driver Validation requires
20 <a href="http://www.keil.com/pack/doc/CMSIS/RTOS/html/index.html" target="_blank">CMSIS-RTOS</a> or
21 <a href="http://www.keil.com/pack/doc/CMSIS/RTOS2/html/index.html" target="_blank">CMSIS-RTOS2</a> functionality and can be
22 used to verify the setup and configuration of the CMSIS-Driver interfaces in a user system. It is also used to validate
23 implementation of a CMSIS-Driver interface.
25 The diagram below is an overview of the configuration for CMSIS-Driver validation.

104 \page test_setup Test Setup
106 \section step1 Step 1: Create an MDK project with your target microcontroller device
109 \section step2 Step 2: Add required software components
111 For proper operation, add the following software components in the <b>Manage Run-Time Environment</b> window:
112 - <b>CMSIS:RTOS2 (API):Keil RTX5</b>
113 - <b>Compiler:I/O:STDOUT</b>, variant \b ITM or \b User if your hardware does not support ITM.
114 - <b>CMSIS:CMSIS Driver Validation:Framework</b>
115 - Any other component from <b>CMSIS:CMSIS Driver Validation</b>
116 - Resolve any validation messages
119 \section step3 Step 3: Add main.c
121 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
122 \b main file from <b>Device:Startup</b> or <b>CMSIS-RTOS2:Keil RTX5</b>.
129 In the main function, after kernel initialization, create the \c cmsis_dv thread:
131 osThreadNew(cmsis_dv, NULL, NULL);
133 to run all tests that you have chosen in the next step.
136 \section step4 Step 4: Configure DV_Config.h
138 Open \c DV_Config.h under the <b>CMSIS Driver Validation</b> group in the Project window.
140 \image html dv_config_h.png "Configuration File DV_Config.h"
142 <b>Common Test Settings</b>
144 The common test settings help you to choose the output format of the test and the buffer sizes and buffer content that should
145 be used for the send, receive, and transfer tests:
146 - The \b Print \b Output \b Format lets you select if you wish to create the output as plain text or as styled XML.
147 - \b Buffer \b sizes lets you select the buffer sizes that are used for data transfer. This setting has a direct impact on
148 required \ref step6 "heap".
149 - You can specify also the <b>Buffer size for baudrate test</b>. For USART you can set the <b>Percentual tolerance for baudrate
150 test</b> and for SPI the <b>Percentual trigger for bus speed test</b>. Depending on the device \ref step7 "configuration", for
151 example when DMA is not used, the transfers may have larger overhead which is more significant for higher bus speeds. The
152 transfer overhead is reduced for larger transfer buffer sizes.
153 - Select your preferred <b>Buffer pattern</b>
155 <b>Driver-specific Settings</b>
157 Every interface has specific settings that can be changed in the according section:
158 - You need to specify the driver instance number (<b>Driver_<i>interface</i>#</b>) used for the test. This is especially
159 important for microcontroller devices that have multiple peripherals of the same kind.
160 - Some drivers can have additional baudrate or timing settings.
161 - Select all driver tests that you wish to use. Note that all tests can run independently from each other. You do not need to
162 specify a certain order.
164 \note For more information on additional settings and the different driver test cases, check the
165 <a class="el" href="./modules.html">Reference</a> section.
168 \section step5 Step 5: Configure Keil RTX5
170 Open \b RTX_Config.h and edit set:
171 - <b>Default Thread stack size [bytes]</b> to \a 2048
174 \section step6 Step 6: Configure Heap
176 Depending on the buffer sizes that you have chosen in \ref step4 "Step 4", you need to add more heap. Open your
177 startup_<i>device</i>.s file from the \b Device group in the \b Project window. Click on \b Configuration \b Wizard. Increase
179 - For the validation framework add 1024 bytes.
180 - double the largest buffer size you have set in the configuration file and add this as well.
182 Refer to the \ref resource_requirements section for a calculation example.
185 \section step7 Step 7: Configure the Device
187 Depending on your device, you might have different pin/hardware configuration options. Usually, you can configure the device
188 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
189 necessary pin-out changes required by your actual board layout (consult the board schematics). The pre-built
190 \ref examples "examples" are already configured for the underlying hardware.
192 For a robust test with good coverage, implement various targets with different settings:
193 - \b Enable/disable the \b DMA controller of your device
194 - Set different \b buffer \b sizes in \ref step4 "DV_Config.h"
195 - Select different compiler \b optimization \b levels in the
196 <a href="http://www.keil.com/support/man/docs/uv4/uv4_dg_adscc.htm" target="_blank">C/C++ tab</a> of the
197 <b>Options for Target</b> dialog.
200 \section step8 Step 8: Make Hardware Connections for Loopback Tests
202 These interfaces support loopback testing: \ref eth_funcs "Ethernet", \ref spi_funcs "SPI", and \ref usart_funcs "USART".
203 Connect the following pins on your target hardware together (refer to the hardware schematics):
205 - Ethernet: RX+ and TX+, RX- and TX-
209 \section step9 Step 9: Add additional test Hardware and Software for WiFi Tests (relevant for WiFi tests only)
211 For testing functionality of WiFi driver it is necessary that there is a SockServer application
212 running in the same network. Check \ref wifi_sock_setup "WiFi SockServer" documentation on how
213 to setup the SockServer application for WiFi testing.
215 \section step10 Step 10: Download and Run the Project
217 In the <b>Options for Target</b> dialog, under debug settings, ensure that \b Trace and ITM port \token{0} are enabled and
218 that the correct clock frequency is set:
220 \image html target_dialog.png "ITM Channel setting"
222 Build, load and run the project. The output is displayed in the <b>Debug (printf) Viewer</b> window:

284 TEST 13: SPI_Loopback_Transfer PASSED
285 TEST 14: SPI_CheckInvalidInit NOT EXECUTED
288 The measured time is depending mainly on two factors: \b DMA and \b software \b overhead.
290 If you are not using \b DMA for data transfer, an interrupt is generated, in worst case, for every transferred byte. The
291 interrupt handling overhead for each byte can produce 10 times slower transfer than DMA. DMA will transfer the data
292 without overhead. Thus, only bus speed/baudrate tests with DMA enabled should be considered for
293 optimization. In case DMA cannot be used (because no DMA channel is left to be used for example), the user needs to be aware
294 that the data rates will decrease significantly.
296 The \b software \b overhead is introduced by the way the measurement is done. When the measurement is started a system tick
297 value is stored and then the transfer is set up and started. The software then needs to determine when the transfer
298 has ended and calculate required time difference by using previously stored system ticks and current system ticks.
299 Usually, the software overhead is a constant number of CPU cycles. The total amount of time required for the software overhead
300 depends on the actual CPU that is used and on the optimization level used during build. \n
301 Increasing the <b>Buffer size for baudrate test</b> reduces the software overhead effect. The following calculation example
304 \b Calculation \b Example
306 SPI bus speed = 25 Mbps
308 - Buffer size for baudrate tests = 512 byte (default value, equals 512 * 8 bit)
309 - Actual bus speed = 18 Mbps (read from driver)
310 - Expected time to transfer data = 227 µs (512 * 8 bit/18 Mbps)
311 - Measured time = 245 µs = 227 µs + 18 µs (coming from a software overhead)
312 - This results in a measured/expected time ratio of 1.08 which will lead to a warning
314 Using a buffer size of 8192 bytes in the example above will reduce the software overhead to less than 1% (which will issue no

519 \section heap_req Heap Requirements
520 Heap is used by memory allocation functions. It is configured in the
521 <a class="el" href="http://www.keil.com/support/man/docs/gsac/gsac_startupcodecortex.htm" target="_blank">startup_device.s</a>
522 file located under the \b Device component class.
524 Additional memory is allocated for the validation framework and for the buffers that are used in the driver tests.
526 For the validation framework add 1024 bytes of heap. Then, double the amount of the largest buffer size specified in the
527 \ref step4 "DV_Config.h" file and add this as well.
529 | Option (under section Heap Configuration) | Increase Value by
530 | :---------------------------------------------------------------- | :----------------------
531 | Heap Size (in Bytes) | + (1024 + 2 x maximum buffer size)
533 \b Calculation \b Example
535 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
536 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
537 <b>Buffer size for baudrate tests</b> to 1024 bytes. This computes to a total heap of 3584 bytes which is equivalent to
538 \c 0xE00. Set this number in the startup file.
