Hi, for a STM32F303RE I configured a pin as an ADC input. I want to use the pullup/pulldown resistors as a voltage divider for an offset voltage. I tried to switch on both in ADC mode, that did not work. Everything is fine with the pin configured as ...
The ADC counts returned by the internal temperature sensor appear to depend on the sampling frequency. In other words, it looks like the temperature sensor can be read too fast (with or without oversampling) to give incorrect temperature readings. ...
Hi all,I have an system that reads data form an external ADC via SPI DMA, i send the StartConversion CMD and when it's done i get and IRQ so i can read the register. I also have an UART communication that polls every 2sec for the new data, I have the...
Hi,I have been able to use the option bytes to configure the Nucleo-G0B1RE to jump straight into the ROM bootloader on powerup and I can see the DFU on Cube Programmer, however on our target board with a G0B0 using the same user option bytes settings...
Hello Community,We are using MEMS OScillator for the clock source for STM32G474 MCU. And are unsure if we can use the OSC_OUT pin as a GPIO pin when using the MCU in Clock Source BYPASS mode.The datasheet mentions we can, I, however, would like to co...
Hi,I was following @Laurids_PETERSEN post on his low power ThreadX example (Part 2 ThreadX Low power Project ). I noticed his sample code, Snippet 11 on Enter Low Power mode configured the APB ENR, AHB ENR in RUN mode and then disabled all the periph...
I am trying to read Analog voltage from two different channel one is mains supply and another is battery voltage.But I am getting both values same in live expression window.Does my config wong.Pls helpvoid ADC_Mains(void) { ADC_ChannelConfTypeDef s...
hello i m using tim1 to generate pwm and using center alligned mode 1 , timer go to 0 to 1800 then 1800 to zero for one pwm cycle and generate 2 intrrupts HAL_TIM_Base_Start_IT(&htim1); //intrrupt i am using//handler is void HAL_TIM_PeriodElapsedCall...
I am using stm32 g071 and what I have done in the code is to toggle pin and send the value through adc and finally output through dac. Theoretically, the GPIO output and DAC output should be simultaneous but due to processing time and all, there will...
