Improve adc accuracy stm32g4
Witryna20 cze 2024 · 1) use a ground plane. 2) use bypass capacitors on the AVDD for the ADC, and on the Vref supplying the charge surges needed during binary-search operation. 3) keep digital currents away from the analog region of the ground plane; perhaps use slits to enforce that separation. 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.

WitrynaThe purpose of this application note is to show how to improve the accuracy of A/D conversions for applications using the STM32F2xx and STM32F4xx microcontrollers. … Witrynasame principles are applied to other ADCs too. The accuracy of analog to digital conversion has an impact on overall system quality and efficiency. To be able to improve ADC accuracy, understand which factors affect errors. The ADC itself, can’t fully ensure the accuracy of results, it depends on the overall system design.
