WebYou'd need to have the correctly named callback which the HAL would dispatch back to you. ie the main IRQ Handler from the vector table calls the HAL_DMA_IRQHandler (), and it in turn dispatches to your callbacks, and then clears sources and exits. Like Reply HBida (Customer) Edited December 14, 2024 at 4:08 PM well, that was fast! WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.

WebDec 20, 2024 · I managed to simulate a DMA transfer error, with the ADC configured in continuous conversion mode and indeed, HAL_ADC_ErrorCallback is called twice: one by the DMA because of the transfer error and another one because just after the DMA auto-deactivation due to that error, an overrun happens in the ADC that is captured by the … WebFeb 11, 2024 · Brief summary: The Portenta H7 has an advertized ADC sampling rate of 3.6 Msps. However, timing the analogRead () function results in a sobering 20 kHz rate, i.e. one ADC read takes about 50 us. The solution is to include DMA in the ADC process. I found one site, which explains it well for the STM32 (even with a video on YouTube):

WebHAL ADC Configuration The next step is to configure ADC and channel selection. But before that enable the clock to ADC using __HAL_RCC_ADCx_CLK_ENABLE (). Here, x is an ADC number. For example, we are using ADC2 in this tutorial. Therefore, enable the clock to ADC2 like this: __HAL_RCC_ADC2_CLK_ENABLE() WebDec 22, 2024 · stm32f4xx_hal_adc.c File Reference.
