I want to drive havfbridge with STM32G474. I am going to use TIMx with channel1 and channel2 to create two PWM signals, that are 180° out of phase and with the same PWM % that is limited to 0% < PWM % < 49%. Because tohose signals have max 50% duty c...

I have tow arrays one named adcData[] that is adc input buffer and Xbuf[] that is output buffer. Now i am calculating some paramaters... But when i use my debuger and Live variables, i get only adcData[] and Xbuf[] is "Failed to evaluate expression"....

Hello. I have a problem with my ADC readings. I use Nucleo 64 with SM32G474 and ADC1 Channel 6. Pin coresponds to A5, Arduino compatible pin on board. No matter what i do, change adc or channel, i get 0 as an output. I use comands MX_GPIO_Init();MX_A...

I think the best way for you to do it is by useing HRTIMx that is high resolution timer.

if you want to see live expresions, you need to uprdate variables slowly. if speed is more than few 10Hz data is not shown.

I discoverd my problems nest. Its not in typecasting it is in declaration. I have few arrays named uint16_t ADC_BUFFER_RAW [ADC_BUFFER_LENGHT];float ADC_BUFFER [ADC_BUFFER_LENGHT];float FFT_BUFFER [FFT_BUFFER_LENGHT];float MAGNITUDE_BUFFER[FFT_BUFFER...

I have the same problem. I read analog values with my ADC and values are type of uint16_t but when i convert my array of values that i get from ADC (Because of doublebuffering) to Float numbers get weird. Is it because of endians, maby overflows i do...
