# Baremetal webserver on NUCLEO-F429ZG
This firmware uses experimental TCP/IP stack of the Mongoose Network Library,
which implements the following:

- A complete [HTTP device dashboard ](../../device-dashboard ) with:
2022-09-11 18:20:53 +08:00
- User authentication
- Real-time device data graph
- Coninfiguration display and update
- MQTT communication with a remote MQTT server
2022-08-30 02:15:48 +08:00
- No dependencies: no HAL, no CMSIS, no RTOS
- Hand-written [mcu.h ](mcu.h ) header based on a [datasheet ](https://www.st.com/resource/en/reference_manual/rm0090-stm32f405415-stm32f407417-stm32f427437-and-stm32f429439-advanced-armbased-32bit-mcus-stmicroelectronics.pdf )
2022-09-11 18:23:58 +08:00
- Interrupt-driven [Ethernet driver ](../../../drivers/mip_driver_stm32.c )
2022-08-30 02:15:48 +08:00
- Blue LED blinky, based on SysTick interrupt
- User button handler, turns off/on green LED, based on EXTI, interrupt-driven
- HardFault handler that blinks red LED
- Debug log on UART3 (st-link)
## Requirements
- GNU make
- [ARM GCC ](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm ) toolchain for build
- [st-link ](https://github.com/stlink-org/stlink ) for flashing
## Usage
Plugin your Nucleo 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
```
