Mbed OS6 STM32 IoT Ethernet Controller

IoT controller using Wiznet W5500

Main branch – simple IO control (no temp, LCD etc, just Inputs and Outputs)

Based on the BluePill (STM32F103C8) support for mbed os:

To Do

• decrease loop timeout if required
• add i2c OLED
• add rotational encoder

BluePill board (STM32F103C8)

Normal variant uses a mix of inputs, outputs and temperature sensing (DS18B20).

Pins

• PC_13 is the green LED output (used to indicate online/offline status)
• PA_0 – PB_0 (left) pins are 9 DigitalIn inputs
• PB_1 (left) is DS18B20 input (needs external 4.7k pull up)
• PB_9 – PA_8 (right) pins are 13 DigitalOut outputs
• PC_14 and PC_15 cannot be used (linked to micro crystal)
• PB_10 is the serial output (115k) used for debug
• PB_15 – PB_12 (right) are for Wiznet SPI, PB_11 for the Wiznet reset (output)
