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 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 toolchain for build
• st-link for flashing

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
