Motion controler code for the RPI Pico (RP2040)
|
||||
===============================================
|
||||
|
||||
This project is the main controller firmware for the RPI Pico (RP2040), designed for the Eurobot 2025 Cup.
|
||||
|
||||
|
||||
I2C description
|
||||
-----------------------------------------------
|
||||
|
||||
The robot’s I2C communication works as follows:
|
||||
* Send the device address + R/W bit (to select read or write mode).
|
||||
* Send the target register address (to read from or write to).
|
||||
* Read or write the register data. Multiple registers can be read/written sequentially, with the address auto-incrementing after each operation.
|
||||
|
||||
This code is designed to be the master in the i2c communication;
|
||||
|
||||
|Adress |R/W|Description |Encoding |
|
||||
|-------|:-:|-------------------------------|:-----------------:|
|
||||
| 0x00 | W | Speed motor 1 |**-128** - **127** |
|
||||
| 0x01 | W | Speed motor 2 |**-128** - **127** |
|
||||
| 0x02 | W | Speed motor 3 |**-128** - **127** |
|
||||
| 0x03 | W | Speed motor 4 |**-128** - **127** |
|
||||
| 0x04 | W | Servo 1 position selection | **0** - **1** |
|
||||
| 0x05 | W | Servo 2 position selection | **0** - **1** |
|
||||
| 0x06 | W | Servo 3 position selection | **0** - **1** |
|
||||
| 0x07 | W | Servo 4 position selection | **0** - **1** |
|
||||
|
||||
|
||||
Motors communication description
|
||||
-----------------------------------------------
|
||||
|
||||
Motors are «connected» to their respective I2C buffer address.
|
||||
|
||||
To control a motor you need to write data to its adress of the form :
|
||||
|
||||
>```C
|
||||
>int8_t speed;
|
||||
>```
|
||||
|
||||
Value goes from **-128** to **127**.
|
||||
|
||||
|
||||
Servo motors communication description
|
||||
-----------------------------------------------
|
||||
|
||||
Servo motors are «connected» to their respective I2C buffer address.
|
||||
|
||||
To control a servo motor you need to write data to its adress of the form :
|
||||
|
||||
>```C
|
||||
>uint8_t close;
|
||||
>```
|
||||
|
||||
Value is 0 or 1 for the open or the close pos.

*
|

* Le principe est que la télécommande soit l'esclave I2C
|
||||
* Pour envoyer un message, on charge le message à l'adresse 0 de la "mémoire" pour l'i2c
|
||||
*
|
||||
* Pour lire le message, le robot interroge la télécommande, et demande le contenu à partir de l'adresse 0 de la mémoire.
|
||||
* Ainsi, en cas d'échec de la communication, le robot détectera une manette débranchée.
|
||||
* Par défaut, la fonction lit 255 caractères.
