# Baremetal webserver on EK-TM4C1294XL
|
||
|
|
|
||
|
|
This firmware uses experimental TCP/IP stack of the Mongoose Network Library,
|
||
|
|
which implements the following:
|
||
|
|
|
||
|
|
- A complete [HTTP device dashboard](../../device-dashboard) with:
|
||
|
|
- User authentication
|
||
|
|
- Real-time device data graph
|
||
|
|
- Coninfiguration display and update
|
||
|
|
- MQTT communication with a remote MQTT server
|
||
|
|
- No dependencies: no HAL, no CMSIS, no RTOS
|
||
|
|
- Hand-written [mcu.h](mcu.h) header based on the [datasheet](https://www.ti.com/lit/pdf/spms433)
|
||
|
|
- Interrupt-driven [Ethernet driver](../../../drivers/mip_driver_tm4c.c)
|
||
|
|
- LED blinky, based on SysTick interrupt
|
||
|
|
- User button handler, turns off/on an LED, based on GPIO IRQs (interrupt-driven)
|
||
|
|
- HardFault handler alternate blinks LEDs
|
||
|
|
- Debug log on UART0 (ICDI)
|
||
|
|
|
||
|
|
## Requirements
|
||
|
|
|
||
|
|
- GNU make
|
||
|
|
- [ARM GCC](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm) toolchain for build
|
||
|
|
- [Uniflash](https://www.ti.com/tool/UNIFLASH) for flashing
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Plugin your board into USB, and attach an Ethernet cable.
|
||
|
|
To build and flash:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ 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:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ picocom /dev/ttyACM0 -i -b 115200 --imap=lfcrlf
|
||
|
|
```
|
||
|
|
|
||
|
