Used as a kill switch for an autonomous RC car.
- 5 physical PWM inputs
- a0: linear
- a1: linear
- a2: on/off, multiplexer input
- a3: on/off
- a4: on/off
- 2 virtual PWM inputs via I2C
- b0: linear
- b1: linear
- 2 physical PWM outputs
- y0: linear, adopts frequency of a0
- y1: linear, adopts frequency of a1
- Outputs are multiplexed between a* and b* channels
- I2C address 0x09 (100kHz)
- Reads provide pulse widths of virtual PWM inputs
- Writes supply pulse widths of PWM outputs
- Pulse widths are measured in 3.02MHz clock cycles
Design is targeted at TinyFPGA AX2, which uses the Lattice LCMXO2-1200HC.
