Need a simple open source/low cost to maintain, GUI that can talk to my external MCU with a UART.
So in summary I need to enter a setpoint and display a couple variables. My other MCU will print a String out its TX port and Discovery board will need to display those variables. If setpoint is adjusted on screen then Discovery board needs to Print a string out its UART6 so my MCU can receive it.
I would also like to add a couple graphics to the screen.
Discovery boards is a STM32F469NI with a 800x480 pixel display.
