Hello,I am troubleshooting a similar problem as described in this post TM32H7 ADC Baremetal - Cannot get ADC module readyI am using PF10 on ADC3 as it is already routed to the CN10 header. Intentionally ignoring CMSIS header/defines in the spirit of ...

Hello, I am following a few examples for bare metal firmware (without HAL or LL) to enable USART. I am using a NUCLEO-H745ZI-Q starting with an empty project. From the users manual I am gathering that the STLink MCU on the board provides a 25MHz (X1)...

Hello, I have a NUCLEO-H745ZI-Q I am using it to self study a bit more at the assembly level of the CM4/CM7. I used STM32CubeMX to create a Make Project for the MCU only i.e. not the BSP / Nucleo board. I did this so I could poke around at the C...

Hello, I am running STM32CubeIDE Version: 1.12.1 on Ubuntu 22.04. I am using a NUCLEO-H745ZI-Q board. Is it possible or reasonable to expect that I should be able to configure the Make tool chain using the STM32CubeIDE instead of the default STMCubeI...

Thank you @MasterT for your time and very helpful write up.

@MasterTThanks again! I really appreciate it. I did not catch that the 7.5ADC Clock cycles was specific to 14 bit. I thought 14 bit was just specific to the example section of page 972 i.e. I thought the equation before the example was for the "gener...

@TDKI am in a kind of exploratory and/or evaluation of the part limits and I do not yet have hard requirements.The current approach I have assumed is to examine the part "specification limits" per the part documents:For 16 bit resolution, LQFP144 = 1...

Thanks @MasterT. This is very helpful. I was using Tcon=Sampling Time + 7.5 ADC Clock Cycles on page 972 of the RM. I will compare the two but at first glance they look different.

Hello again,I managed to make progress but with little understanding of why? I forcefully clear the ADC OVERUN bit just before the EOC while() check.I went back to setting the HSI to its default 64MHz. Either way the ADC "works" be it HSI 64MHz or 32...
