Baremetal webserver on NUCLEO-F429ZI

This firmware uses MIP, an experimental TCP/IP stack of the Mongoose Network Library, which implements the following:

• A complete HTTP 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 header based on a datasheet
• Interrupt-driven 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
• stlink for flashing

The links above will send you to tutorials on how to install each of those tools in your workstation for Linux, Mac, and Windows.

Usage

Plugin your Nucleo 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 but for the NUCLEO-F746ZG board
