STM32F779AIY6 - What if NC pins are connected to GND?

Hello,i just received some custom boards with a STM32F779AIY6 on it.3V3 net and GND net have a short circuit when MCU is soldered, without MCU there is no short circuit.I checked everything, it should be fine.But what i just found was that the datash...

Why is my ADC reading zero for values?

My objective is to utilize ADC peripheral for reading analog signals and converting them to digital. I am using the polling method for reading ADC values. When setting up the chip configuration, I am currently using the Nucleo-H743ZI with default set...

Resolved! In RM0394 Rev 4 page 873/1600 field OCM1 is bits 6:4 which I count as 3 bits. But the description shows the settings as 4 bits with 16 choices.

For example: 1000: is Combined PWM Mode, 1111: is Asymmetric PWM Mode 2. How do you fit 4 bits into 3 bit spaces? Bit 7 is used for OC1CE, and Bit 3 is used for OC1PE so there is no space on either end for the extra bit.
