Detailed Description

OBDII Click Example.

Description

This example demonstrates the use of OBDII click board by reading the engine RPM and vehicle speed and displaying results on the USB UART.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

Application Task

Reads and processes the engine RPM and vehicle speed and displays the results on the USB UART once per second.

Additional Function

• static void obdii_clear_app_buf ( void )
• static err_t obdii_process ( obdii_t *ctx )
• static void obdii_log_app_buf ( void )
• static err_t obdii_rsp_check ( obdii_t *ctx, uint8_t *rsp )
