Thank you for your interesting post. I had never heard about embassy for rust, so this was really interesting to learn something new! Embassy seams to be a very good HAL för ST32. I have ordered a NUCLEO-WL55JC2 with wifi and lora to start experimenting! Looking forward to more posts on this subject!
Best regards, Greg in Sweden.
PS. I'm missing how to make and connect the serial cable. DS.
