Control Commands
- Pin Definition
- All pins connect to ground pin of LED
- All commands should be end up with \r\n
| Pin | MCU PIN | v1.1 Command | v1.0 Command | Note |
|---|---|---|---|---|
| 1 | PB5 | 1N - 1F | N1 - F1 | |
| 2 | PB4 | 2N - 2F | N2 - F2 | |
| 3 | PC3 | 3N - 3F | N3 - F3 | |
| 4 | PC4 | 4N - 4F | N4 - F4 | |
| 5 | PC5 | 5N - 5F | N5 - F5 | |
| 6 | PC6 | 6N - 6F | N6 - F6 | |
| 7 | PC7 | 7N - 7F | N7 - F7 | |
| 8 | PD3 | 8N - 8F | N8 - F8 | Also connected to Bluetooth status LED pin (1) |
| 9 | PD2 | 9N - 9F | N9 - F9 | |
| 0 | PD4 | 0N - 0F | N0 - F0 | |
| A | PA1 | AN - AF | NA - FA | |
| B | PA2 | BN - BF | NB - FB | |
| C | PA3 | CN - CF | NC - FC |
- When Bluetooth made connection, BT status LED will keep constant high, you can not write it low, notice. But you can read the BT status via this pin.
Serial Debugging
Bluetooth UART connect to serial UART debugger
- board TX to cable RX, board RX to cable TX:
| Receive | Action | Send from | example |
|---|---|---|---|
| Serial monitor | only response < | Phone CMD | "N1" |
| Serial monitor | NOT response < | Serial monitor CMD | "N1" |
| Phone | get < | MCU feedback | "mssage is ..." |
| Serial monitor | NOT get < | MCU feedback | "message is ..." |
MCU UART connect to serial UART debugger
- vice verse connection
| Receive | Action | Send from | example |
|---|---|---|---|
| Serial monitor | response < | Serial monitor CMD | "N1" |
| Serial monitor | NOT response < | Phone CMD | "N1" |
| Phone | get < | MCU feedback | "message is ..." |
| Serial monitor | get < | MCU feedback | "message is ..." |
