Share. 0) Build and debug the project. I was first try to use the arduino Nano. Using STM32F4, STM32F103 Blue Pill Servo HAL. Debugging the code I saw that function "HAL_ADC_PollForConversion(&hadc1, 1000)" never returns "HAL_OK". Analog-To-Digital Conversion reviewing the codes in the core, hal and in particular the manual e. I think this is may be helpful somebody. What is Analog Watchdog: Analog watchdog is a mechanism that allow the ADC to generate interrupt when the ADC values is above the high threshold level and below low threshold level. h. After quite some time spent understanding why the voltage read by the MCU didn't correspond to what I saw with the multimeter, I realized that using analogRead() means by default using the In this post, I will be configuring and setting up an stm32f4xx-hal ADC to measure ambient temperature using the NCP18WF104F03RC NTC Thermistor. The development pathway to access these features is different and quite daunting if your primarily familiar with the Arduino platform. void HAL_ADC_ConvtCpltCallback (ADC_HandleTypeDef *hadc) {value = HAL_ADC_GetValue (&hadc1); } Here how can I read multi channel readings in ex: value[3] buffer. For this reason, I wanted to show how to set up the DMA manually in the previous example. 5 cycles: The code is as follows HAL_ADC_Start(&hadc1); // start the adc HAL_ADC_PollForConversion(&hadc1, 100); Provides several examples for the Arduino core for STM32 MCUs.
