This is a replacement for a TASCAM RC-10 remote control running on Arduino.
The RC-10 communicates over a 2.5mm stereo headphone plug. The tip is the signal from the remote control to the device under control (such as an audio recorder), the ring is 3.3V DC from the device, and the sleeve is ground.
The protocol is standard TTL-level UART (mark is 3.3V, space is 0V) running at 9600 baud, 8 data bits, even parity, and 1 stop bit.
The RC-10 sends a start byte when a button is pressed, a repeat byte every 100ms afterward while the button is held down, and an end byte when the button is released. The lower 5 bits of the byte is the command, while the upper 2 bits indicate whether it's a start, repeat, or end byte. A start byte has bit 7 set and bit 6 cleared, a repeat byte has both bits 7 and 6 set, and an end byte has both bits 7 and 6 cleared.
| Button | Value |
|---|---|
| Stop | 8 |
| Play | 9 |
| Record | 11 |
| Forward | 14 |
| Back | 15 |
| Mark | 24 |
| F1 | 28 |
| F2 | 29 |
| F3 | 30 |
| F4 | 31 |
Note: F3 is marked (+) and F4 is marked (-).
This replacement software also supports a "turbo" mode which increases the repeat rate of buttons to 2x the normal rate. This is useful for impatient people. :) Turbo mode can be toggled with a press of the turbo button.
