MIP webserver over FreeRTOS on EK-TM4C1294XL
This firmware uses MIP, an experimental TCP/IP stack of the Mongoose Network Library, running as a FreeRTOS task. It implements the following:
- Minimal elementary web server, as simple as possible
- No dependencies: no HAL, no CMSIS
- Hand-written mcu.h header based on the datasheet
- Interrupt-driven Ethernet driver
- LED blinky, based on another FreeRTOS task
- Debug log on UART0 (ICDI)
Requirements
The links above will send you to tutorials on how to install each of those tools in your workstation for Linux, Mac, and Windows.
You'll also need git so the Makefile can clone the FreeRTOS-Kernel repository. We assume you have it since you got to get this repository somehow. If you don't, and don't want to install it, just get the proper FreeRTOS-Kernel version (see the Makefile) from its repository, as you did with the Mongoose repository.
Usage
Plugin your board into USB, and attach an Ethernet cable. To build and flash:
$ make clean flash
To see debug log, use any serial monitor program like picocom at 115200 bps and configure it to insert carriage returns after line feeds:
$ picocom /dev/ttyACM0 -i -b 115200 --imap=lfcrlf
There is also a detailed tutorial on this example
