Re: STM32F407Disc : Write data on LCD
Okay. While using your asynchronous mode code, their is an import error at time of importing uasyncio module i.e "" import uasyncio as asyncio ""
I have downloaded your project, and searched for the module "uasyncio" its not appearing. So how to get this module or any other alternative ?
Thanks
