Hello,I have STM32G031 and I want to use PA8 pin (TIM1_CH1) to count pulses. My idea is to read number of counted pulses every 1 second and reset counter to 0. void TIM1_Init(void) { // Enable TIM1 clock RCC->APBENR2 |= RCC_APBENR2_TIM1EN; ...

Hello, I need help with ADC and DMA settings. My application is VERY EASY but I do not understand the setup parameters. The application is that I just start CPU and the ADC raw value should independently transfer via DMA to variable. When I need the ...

Hello I need to send a string via USART every 500ms. I tried to use DMA that seems to be easy to configure. USART transfer works but only without DMA (test in while main cycle). I do not see any problem in DMA configuration. Can you tell me it there ...

Hello, I am not able to program STM32G031. I have Nucleo kit F401RE and STM32G031 connected to SWD. I have connected SWDIO, SWCLK, 3V3, GND and nRST.STM32CubeProgrammer can connect only in Hot Plug mode, but writting or errasing gives me: Error: Mass...

Hello,I need to calculate motor load (triac controlled 1-phase universal motor on drilling machine) on ADC input of STM32G030. This is output from Hall sensor TMCS1101A2BQDR and the main frequency is 50 Hz. Triac speed control makes the pulse current...

Solved, this is wrong settings: TIM1->SMCR |= TIM_SMCR_SMS_2; // External clock mode 1This is correct:TIM1->SMCR |= TIM_SMCR_SMS_2 | TIM_SMCR_SMS_1 | TIM_SMCR_SMS_0; // External clock mode 2 (SMS = 111)

Thank you for all. Finally I found a way:static void ADC_Init(void){ // Enable the ADC clock RCC->APBENR2 |= RCC_APBENR2_ADCEN; // Enable the ADC voltage regulator ADC1->CR |= ADC_CR_ADVREGEN; // Wait for the voltage regulator to stabilize...

It is OK, it is output from hall-probe, galvanicaly isolated. TMCS1101A2BQDRQ1 is the part, it works fine by hardware side. The problem what i have is mostly firmware side :(

My signal is current feedback from the triac controlled motor. When I switch on the triac, I start to find maximum/minimum (it is offseted to 3.3V/2) current peak to check overtorque.So it is 100Hz half-period and ever half period I need to find maxi...

This is very good point, I did not realize it! Thank you!Output impedance of my source is around 1 kiloohm, so not very small. Am I correct that in this case I need to setup as sampling time as possible? Is necessary to have 160 Cycles?Sampling time ...
