The Wombat serial is an intelligent I/O expansion chip compatible with Arduino, Raspberry Pi, CircuitPython, native embedded systems, PC or any other system that can communicate via I2C.
The Wombat 4B serial provides 3 input/output pins and an input pin that can run an independent status machine every millisecond to perform intelligent operations.
Communication uses a simple I2C protocol with up to 400 kbps.
This set contains four pre-programmed Serial Wombat 4Bs with I2C addresses 0x6C, 0x6D, 0x6E and 0x6F. You can also change the address with a sketch in the library examples.
Input Pin Modes:
Pulse measurement - pulse measurement with 8uS resolution
- Debounced input - Debounced switches and keeping track of press count and press time.
- Quadrature Decoder - Combine two input pins to monitor square encoder signals
Input/Output Pin Modes:
-Analog input (10-bit with filtering, average and min/max tracking).
- Servo output (1uS pulse resolution) PWM output (10 bits at selectable frequencies).
-Watchdog - Reset the host when locked - Turn off output when error is detected.
-I2C -> UART bridge
