nucleo f401re uart example
So now I can send data out via serial from the F401 nucleo board. Cool. But there is still one caveat:
The data I receive is distorted. Not all the char but roughly 3 out of 4.
For every char I send, I will receive one char.
I added delays sending between chars. same issue. So obviously no overfow issue.
I started switching baudrate. But no change.
I checked with my Saleae LA, hooking up to the TX/RX pins on the programmer board (right next to teh SWD header).
I see the same serial stream I see on the Host/PC side. So the corruption seems to already happen when the STM 32 F401 sends the data out.
I am using for testing the STM32 demo sample. So not sure what is wrong.
Anybody else encountered similar behaviour?
I never had such issue with my other ST board. So I am at loss right now.
Is there something wrong with the initialization of the chip?
