Hi,I have setup the ADC in STM32H753ZIT6 to sample 4 channels with DMA in circular mode. This works as expected and I can check the values being updated in the "Live Expressions" tab.But there is an offset, which I can only get rid of, if I perform t...

Hi,I have tried to setup the ADC in STM32H753ZIT6, to sample more than one channel by using the polling method.So far I have not been successful. I have tried to follow guides and Youtube videos. What they all seem to do is to enable the wanted chann...

Hi,Hope this is a simple question.I use this device: STM32H753ZIT6I don't intend to use USB so looked in the datasheet and found the belowDoes that mean I can safely connect VDD33USB to GND?Thank you.

Hello,Just a clarification question. When going through the application note (AN5248) for ST25R95. It mentiosn at one point there is a maximum allowed voltage on RX1 and RX2 which should be below 7V.Where in the datasheet is this specified? Thank you...

HiI am using STM32H753VIT6 together with LAN8742A.I have some questions regarding the setup.1. My schematic for the LAN8742A is shown in the picture below. I plan to use the PHY to generate the clock. To my knowledge this requires a pulldown resistor...

Thank you for your answer.I am not sure what has happened in the meantime, but it works now. I calibrate once and start the ADC with DMA and everything is running and precise.

Hi,Thank you for the reply. I think I will park this for now as I will use the DMA method instead. Whgich I can get to work but now I have a calibration issue, which I think I will open a new thread on.Thank you all. Br.
