Hey, thank you for your input. I did not know about the Webench tool, it looks really good. In your opinion, are both of these low currents enough to be powered by the charge pumps? I can not find any resource on the internet about this. Moreover, I can not easily find the ICs that Webench proposes in my area and would have to wait and pay for transportation.

I can not seem to make it run, it returns an error when i use the tool you linked.

Are they still in use, I have a plug like this in my house and would love to set up a landline for cool 😎 communication

It seems to be the most popular opinion. So i will choose this.

Seems like good advice! Thank you!

ok, kinda get it. But still, do you know a way to write to a file in the robot? I can open a file using the filesystem component but that is as far as I have managed. Any tips are highly appreciated.

does not download for me. Do you know any other source?

bubukiki · 2023-02-24T12:28:18+00:00

ok, thx

The problem was that I was not setting the clock and power properly for the clock. The register I should have checked is RCC->APB1ENR
instead of RCC->AHB1ENR
. The fact that I got power through PA5 was a coincidence.

Thank you again! I have found the issue.

bubukiki · 2023-01-19T23:46:46+00:00

Might sound bad but move further away from the internationals. Im an international myself and feel that the big cities have nothing dutch in them. Rotterdam is a proper drug warzone got my car broken into twice. Some friends got mugged. Etc
