Opto Encoder 2 click is a linear incremental optical sensor/encoder click which can be used for the movement or rotation encoding.
We provide a library for the OptoEncoder2 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for OptoEncoder2 Click driver.
void optoencoder2_cfg_setup ( optoencoder2_cfg_t *cfg );
OPTOENCODER2_RETVAL optoencoder2_init ( optoencoder2_t *ctx, optoencoder2_cfg_t *cfg );
uint8_t optoencoder2_pwm_get ( optoencoder2_t *ctx );
uint8_t optoencoder2_int_get ( optoencoder2_t *ctx );
int32_t optoencoder2_get_position ( optoencoder2_t *ctx );
This application is used to encode motion or rotation
The demo application is composed of two sections :
Initializes GPIO driver and resets encoder counter to 0(zero)
If encoder is moving - increments or decrements encoder position on every rising edge on Channel A (INT pin) and logs encoder position
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
