# Baremetal webserver on NUCLEO-F429ZG
|
||
|
|
|
||
|
|
This firmware uses experimental TCP/IP stack of the Mongoose Network Library,
|
||
|
|
which implements the following:
|
||
|
|
|
||
|
|
- Implements HTTP server and SNTP time synchronisation
|
||
|
|
- 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)
|
||
|
|
- Interrupt-driven [mip_driver_stm32.h](../../../drivers/mip_driver_stm32.h) ethernet driver
|
||
|
|
- 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
|
||
|
|
```
|
||
|
|
|
||
|
