Overview
Encoder to i2c tssop20.kicad pro panelized is an open-source printed circuit board by prosper00, from the prosper00/Encoder-i2c repository on GitHub, published under the MIT licence. It is a 2-layer board of 96.3 × 71.6 mm with 234 parts on 35 nets, routed with 1,554 tracks and 138 vias.
Its parts include 120 resistors, 72 diodes, 24 capacitors, 6 ICs and 6 connectors. It belongs with the RISC-V boards of this library.
README
README.mdsimple ch32v003 firmware to read a rotary encoder input device, and convert it to i2c.
Usage / notes
- configured for a CH32V003 SOP8 package
- encoder inputs are connected to PA1 and PA2
- encoder pushbutton is connected to PC4
- all encoder pins are externally RC debounced and pulled up [ see /hardware for schematic ]
- device is configured as an i2c slave device on address 0x09.
- 'read' two bytes: the first byte is the rotation value, and the second byte indicates whether the button has been pressed
- values are reset to zero after a read
- no software debounce or acceleration scaling has been implemented
- i2c writes not currently implemented. TODO: update this firmware for a 20-pin package, and use writes to light LEDs
