WitrynaSTM32G4: First ADC samples are not correct Summary: I am sampling the internal voltage reference 5 times using DMA with the ADC set to continuous mode with LL_DMA_LIMITED. I know about the errata that says to ignore the first ADC value, but the other 4 values only become consistent if I use a HAL_Delay(1) after enabling the … Witryna1. -1 Misleading You have posted the data sheet of an entirely different and substantially more limited stm32 series sub-family. The F4 mentioned in the question, in addition to being a Cortex-M4 rather than the Cortex-M3 STM32F101 you show has up to 3 ADCs depending on the specific device/package chosen.

WitrynaSince we want the ADC to use DMA, we also need to configure a DMA channel to capture the data: Here we configure the DMA channel to use a circular buffer. In other words, each time a value is sampled, the memory address is increased for the next sample. Calibration. The ADC measures analogue values as a fraction (4095) of VDDA.
