blackboard-STC15

A firmware for STC15L2K32S microcontroller on Black Board T5 ESP-13

Use SDCC to compile

Use STC MCU ISP flash tool to programm

Install both sdcc and stcgal per instructions (or use distribution packages for sdcc)

make make install # will download to the MCU

What it supports for now:

• [x] STC15 UART (baudrate: 115200)
• [x] Reading on-board DHT11 values
• [x] One-wire communications (DS18B20 temp sensor) via P1.5 (pin 4 of 5-pin header)
• [x] I2C communications via pins 2 and 3 (SDA/SCL) of 5-pin header (tested with BH1750 light sensor)
• [x] Using PWM to flash on-board RGB LEDs
• [x] On-board beeper
• [x] On-board relay

TODO

• [ ] 2nd UART to interface ESP chip
