Hello,I have a project that sends a signal between master (stm32 and Ebyte+antenna) and a slave (another stm32 and Ebyte+antenna) using UART (baudrate 9600) (The communication between the Ebyte and the antenna is fine).My code is fine, it is not comp...

Hello,I am trying to get information from two analog sensore (FSRs) by using two seperated data lines (PB0 as IN15 and PA7 as IN12) through ADC1(Not important note - I created unint32s for debuging and I am willing to transfer the data by using CANBU...

Everything works.Thank you for your help!

I have figured it out!There are S&H capacitors (Sample and Hold) in the ADC inputs and they are probably connected between the data lines, than there are parasitic noises(current that moves between the capacitors) between them and thats why I had thi...

I've used 5V from external supplier, I tried 5V VDDA and I tried 3.3V external and internal too.Unfortunatley it doesnt matter.By the way I have used STM32F303K8 to try seperated ADCs (ADC1 & ADC2) without DMA and it still dependent somehow.

I can see in the scope that there are changes in voltage, I think it happans becuase the sensors are connected to GND through an 10Kohm resistor and there is leakage of data to GND.In addition I'm trying to write a code for stm32F303K8 which has two ...

Hello and thank you for your quick response.The only connection between the two sensors is the GND and 5V lines through the board.The sensors are simple resistors. so I cant see why they would affect each.If I will check them with the scope I will se...
