I am working with STM32H747i-DISCO board and I configured ADC1 with DMA1 stream0 and ADC3 with DMA2 stream0 both with Cortex-M7 core as initializer and I created the MDK-ARM project using STM32Cubemx and compile the code in CrossWorks when I debug t...
Hi Can anyone help me understand the difference betweena) writing control loop and obtaining ADC values in HAL_ADC_ConvCpltCallback with ADC ISRsinstead ofb) writing control loop and obtaining ADC values in HAL_TIM_PeriodElapsedCallback using TIMER I...
I am using a STM32F767BITx LQFP208. I have to measure 12 channels. 6 channels measure the voltage and 6 other channels measure the intensity. Samples from voltage and insitensities shall be done as simultaneously as possible.I am using ADC1(voltage) ...
Our product uses a STM32L452 to measure the 4-20mA loop current of an external sensor. The product has an operating temperature range of 0-40°C.The STM32L452 datasheet (Tables 78 to 82) lays out the accuracy specs for the internal ADC but aside from ...
Many ST documents says that FT pins are 5V tolerant only in (Digital) Input mode. They are not 5V tolerant when configured in Analog mode and analog peripheral like ADC or OPAMP is connected to it. But are they 5V (or more precisely Vdda + 3.6V toler...
Hi , I am trying to calibrate ADC in STM32334R8. But the code is stoping at calibration phase itself. I will attach the initilization code below for your reference. LL_ADC_Disable(ADC1);LL_GPIO_ResetOutputPin(GPIOC,LL_GPIO_PIN_8);LL_ADC_EnableIntern...
I am using hrtim to trigger the adc, but if the regular channel is not triggered with hrtim, it doesn't go into the interrupt of the ADC properly, I checked a lot of information and didn't find a solution, here is my code and cubemx configuration: N...
We are using an STM32G491 with TDM audio output active on SAI. When activating the 4 MHz bit-clock on SAI1_SCK_A, Vref and temperature measurement become very noisy, while externally connected ADC inputs are not affected.See attached graph for differ...
Hi,As from the title, is it possible to use the same AWD to monitor 2 channels from 2 different ADCs?Specifically, I have a designed a simple digitizer around a f303k8. ADC1 and ADC2 have been configured in continous mode, with AWD2 and AWD3 as monit...
Hi, I am developing digital control for power electronics for which ADC conversion time is critically. In stm32f334r8 reference manual I saw it takes only 0.19us at lowest sampling time i.e 1.5 cycles. when I tried to measure the adc conversion time ...
