[feature request] being able to change UART(0) speed without recompiling.
Description
As a followup to https://github.com/micropython/micropython/issues/6862
I propose to find a way to change URAT(0) speed globally or momentarily.
Globally: a simple entry in a configuration file would be nice.
Programmatically:
something like:
micropython. repl_stop()
Then:
uart = machine.UART(0,921600)
uart.write("Hello 921600 World!")
micropython. repl_restart()
Code Size
Probably small.
Implementation
I hope the MicroPython maintainers or community will implement this feature
Code of Conduct
Yes, I agree
In the machine library and/or the pyb library, add a non-blocking UART transmit polling function
Description
STM32 UART.c inlines (via UART.h) the testing of the UART tx available bit and does not make the result publically available. This by definition eliminates the simplest way to implement cooperative multitasking, viz. spinning around a collection of non-blocking functions. Ironically, the machine library includes a POLL_HOOK function which is used by asyncio - however running up the asyncio learning curve is a high price to pay for a simple requirement. Given that the rx_any function has been provided for a non-blocking UART receive, it seems a bizarre oversight not to have provided the equivalent function for UART transmit.
