Hello,I am using a NUCLEO-G431KB with IAR EWARM 9.20.2 and trying to achieve a 250 ns ADC conversion time on ADC1 (IN1, Single-Ended mode).Configuration: 12-bit resolution, 2.5 cycles sampling time, ADC clock at 60 MHz (synchronous/2, SYSCLK 120 MHz,...

Hello,I am working with an STM32 G4 series microcontroller and using the ADC in DMA mode to handle continuous conversions. My goal is to SET a GPIO (debug pin) at the start of an ADC conversion and RESET it at the end of the conversion.Currently, I a...

I could not turn off the NVIC for ADC as it is enabled by default when using DMA.However, I disabled the NVIC for TIM7 and started the timer normally using HAL_TIM_Base_Start(&htim7);.Now, everything works as expectedwhile(1) is working.Thank you! No...

Does the 30 kHz signal waveform really change every period? I am constantly getting a 30khz sine wave (i checked it with osciloscope)Do you really need the DAC for generating the waveform?Other than that, how can i? with function generator?

do you mean in stm32g4xx_it.c ?/** * @brief Conversion complete callback in non-blocking mode. * @PAram hadc ADC handle * @retval None */ __weak void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef *hadc) { /* Prevent unused argument(s) compila...

You can reply as follows:In while(1), I need to process ADC values (a sampled sine wave) to compute amplitude and phase shift with respect to the DAC output or input signal. This involves mathematical computations like averaging, square root calcula...

It seems the issue is related to the timer settings. Even after commenting out the ADC half and complete callbacks, the program still doesn’t reach while(1). However, when I increase ARR or PSC, the issue is resolved.Initially, with PSC: 3-1 & ARR: 1...
