Posted on February 26, 2018 at 09:52Hi all,I am using the ADC with DMA configured in one-shot mode. We are using the STM32F071V8 controller. Page number 246 of the Reference manual says that - In this mode, the ADC generates a DMA transfer reques...
Posted on February 14, 2018 at 14:33Hi all,We are using a STM32F071V8 MCU in our project. I am polling the ADC to read the data and have followed the following procedure to initialize the ADC:1. enable clock to respective GPIOs2. Initialize GPIO pin...
Posted on November 02, 2017 at 07:43I have configured the ADC in discontinuous mode and sampling 6 channels using DMA which is configured in one shot mode. Also, I would like to poll for the ADC conversions for other channels when the DMA is not act...
Posted on February 16, 2018 at 16:28Thank you for the explanation. It was very helpful. I had an additional query. I am currently reading 6 analog channels using the DMA one shot mode. The DISCEN=0 and CONT= 0(I am sampling multiple channels in sin...
Posted on February 15, 2018 at 16:03Hi AvaTar,Thank you for the response. I am not using the VBAT and the temperature sensor in my code. I had configured them initially only to read the values. When you say drag effect, are you conveying that the va...
Posted on February 15, 2018 at 08:24Hi TJ,Thank you for the response. I will probe the Vdd/Vss for noise. I need to sample the ADC data as quickly and efficiently I can. I have 0.1 and 10 uF caps on the Vdd/Vss pins.
Posted on February 14, 2018 at 15:10The data sheet mentions the minimum sampling time to read the Vrefinit as 4usec , so that explains the behavior probably.
