I have not yet succeeded with the example TFT-Voltmeter a different ADC channel than A0 (PA0) successfully to use.
For the channel channels A1 (PF10) to A5 (PF6) I get incorrect analog values.
Please help me so these channels work properly.
thanks

Hi jopelabln,

when I made the example I tested only the input PA0 which is A0 and is working.
Now I just cross checked the channels you mentioned and you are right: they seem not to work.
But this is a core issue and danieleff is its maintainer.
Sometimes he is reading this post and reacts quite soon. If not, it is probably the best you directly place the issue in his github-repository.

Just place an issue here:
https://github.com/danieleff/STM32GENERIC/issues

Cheers,
ChrisMicro

This is because I thought ADC1 can covers all analog input channels, but PF10..PF6 are on ADC3. I will check on the weekend.

BTW: I think for boards like the STM32F746 Discovery with an Arduino compatible connector the Arduino definitions should be added like:

#define A0 PA0
#define A1 PF10
...

I've made a new game of life.

I think the F7 is quite fast calculation all the cells on the screen
I could watch the evolving cells for hours :D

Hey everyone! Hello from Canada! Please forgive me if this is the incorrect place to post this question as I am new to the forums here.

USART6 - I cannot for the life of me find how to initialize the port.

I know it'll be "USART6.begin(115200);" but that will not take.

What am I missing?

Thank you in advance.
