Collection of my own libraries for interfacing with MCU-peripherals or ICs
- Library for I2C-GPIO-Expander PCF8574 with open-collector pins
- Writing/reading pins (supply mask and pins will be asserted high to be read)
- Generic interface via I2C-Callback functions
- LCD Library:
- Tested with 1602 and 2004 + PCF8574
- Cursor functions: Moving to position, reading current position
- Print functions: Get/Set character at cursor, print text with optional line-wrap at position (x,y)
- Display functions: Cursor, blink, scroll,
- Generic interface via callback functions
- Can be used with I2C-GPIO-Expander PCF8574
- No callback for parallel operation via GPIO supplied yet
- 4-bit and 8-bit mode (latter is in testing phase)
- Busy Flag checking and correct start-up delays
- Custom Character RAM write
