mbed_official 235:685d5f11838f 18 [..]
mbed_official 235:685d5f11838f 19 The CRC HAL driver can be used as follows:
mbed_official 235:685d5f11838f 20
mbed_official 532:fe11edbda85c 21 (#) Enable CRC AHB clock using __HAL_RCC_CRC_CLK_ENABLE();
mbed_official 235:685d5f11838f 22
mbed_official 235:685d5f11838f 23 (#) Use HAL_CRC_Accumulate() function to compute the CRC value of
mbed_official 235:685d5f11838f 24 a 32-bit data buffer using combination of the previous CRC value
mbed_official 235:685d5f11838f 25 and the new one.
mbed_official 235:685d5f11838f 26
mbed_official 235:685d5f11838f 27 (#) Use HAL_CRC_Calculate() function to compute the CRC Value of
mbed_official 235:685d5f11838f 28 a new 32-bit data buffer. This function resets the CRC computation
mbed_official 235:685d5f11838f 29 unit before starting the computation to avoid getting wrong CRC values.
