Hello.I encountered a truncation error issue while working on a grid-connected converter application with the STM32G474MET6 MCU. To manage multiple ADC channels, I opted for DMA to obtain 12-bit ADC converted values. However, I've noticed a bit trunc...

I appreciate your helpful response.I observed that increasing the sampling cycle deteriorates the truncation error. However, the issue has been successfully resolved. The root cause was insufficient power supply to the VDDA pin. Once I addressed this...

I appreciate your helpful response.I discovered that the voltage at the VDDA pin was unstable. Upon investigation, I determined that the 3.3V regulator IC had insufficient output power for the demands of the VDDA pin. When I switched to a regulator I...
