This project implements software serial communication without the use of interrupts or threads. Initially, the goal was to convert the SoftSerial library, but I encountered difficulties in achieving functionality.
It is important to note that the Arduino library does not support independent sending and receiving. The thread scheduling is set at 1 ms, which means that the high-speed responsiveness required for serial communications cannot be achieved through multithreading.
Since this library relies on the implementation of wait_ns for each microcontroller within MBED-OS CE, its performance will heavily depend on how wait_ns is implemented for each specific microcontroller.
While this project may work well for low-speed and high-clock MCUs, it may face challenges with other configurations that have lower CPU clock speeds. Currently, the project is based on the NUCLEO-F207ZG board, but you will need to modify the settings to make it compatible with other CPUs.
Use it at your own risk. I don't guarantee the performance of this library.
- Clone it to your machine. Don't forget to use
--recursiveto clone the submodules:git clone --recursive https://github.com/MariwanJ/BasicSerial - You may want to update the mbed-os submodule to the latest version, with
cd mbed-os && git pull origin master - Set up the GNU ARM toolchain (and other programs) on your machine using the toolchain setup guide.
- Set up the CMake project for editing. We have three ways to do this:
- On the command line
- Using the CLion IDE
- Using the VS Code IDE
- See more at MBED OS CE how you can flash or simply send the bin file to your virtual drive of your Nucleo
- Inside your cpp file under /src do not use #include <balbla.h> , you should write the include with quotation marks .i.e. #include "balbla.h".
- Run the batch or bash file to compile.
