Hello, there,I need CRC8 in my design. Thinking with the Polynomial programmability in Stm32G4 . It should be straight forward.When I tried to test with the example "CRC_UserDefinedPolynomial" coming with stm32cube_fw_g4_v130 in "Examples_LL" folder,...

Hello,When I was trying to use PWM complementary outputs of TIM1, I used CubeMX to create the C code but was not able to turn on the N output while the P output shows right period and duty cycle but no deadtime inserted. Tried many CubeMX configs and...

CRC is not rocket science at least in application. Done many with FPGA and software by shifter and LUT. I can simply implement it in code without spending time on it. Just the curiosity was not satisfied. As you mentioned, it's very sensitive to the ...

Thanks to the OPs who viewed this thread, especially @waclawek.jan and @TDK. Just to update in case it can be helpful to anyone may run into it.I dug a little more in the Calculate_CRC() of the example, seems the original code trying to use the 32B c...

I tried both http://www.sunshine2k.de/coding/javascript/crc/crc_js.html and https://crccalc.com/. These two match well.Then I tried various Input/Output Reflect (Reverse or Non-reverse), Initial value(0x0 or 0xFF). So far, none match the result from ...

Hi, TDK,I understand possible impact of the parameters you mentioned. But to my understanding, even those match, the result still doesn't match.Thanks.YW

Hi, JW,Thank you for your attention.Here is the settings( all copied from the example since I just want to test :(the files are in \STM32Cube\Respository\STM32Cube_FW_G4_V1.3.0\Projects\NUCLEO-G474RE\Examples_LL\CRC\CRC_UserDefinedPolynomialvoid MX_C...
