# Baremetal webserver on NUCLEO-F746ZG
|
|
|
|
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
|
|
- Implements 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/rm0385-stm32f75xxx-and-stm32f74xxx-advanced-armbased-32bit-mcus-stmicroelectronics.pdf)
|
|
- Interrupt-driven [Ethernet driver](../../../mip/driver_stm32.c)
|
|
- 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
|
|
```
|
|
|
|
## Benchmark
|
|
|
|
A quick comparison is made with several other implementations.
|
|
Note: `IP` in the table below is the IP address printed on the console after
|
|
boot. The benchmark command is the same: `siege -c 5 -t 5s http://IP`

|
|
|
- Zephyr: uses Zehypr's RTOS and TCP stack, with Mongoose library on top,
|
|
[source code](https://github.com/cesanta/mongoose/tree/master/examples/zephyr/http-server).
|
|
(*) By default, Zephyr example is TLS-enabled. To compare sizes, a TLS-disabled
|
|
build was done by disabling TLS in `prj.conf` and `CMakeLists.txt`
|
|
- LWIP sockets: uses FreeRTOS and LWIP with sockets support, with Mongoose
|
|
library on top, [source code](https://github.com/mongoose-examples/stm32-nucleo-f746z).
|
|
built with `#define MG` in `Core/main.c`
|
|
- LWIP raw: uses FreeRTOS and LWIP without sockets, LWIP's httpd server,
|
|
[source code](https://github.com/mongoose-examples/stm32-nucleo-f746z).
|
|
built with `#define MG` line commented out in `Core/main.c`
