| File Name | Description |
|---|---|
| main.c | This file contains the main routine which has the application code. This includes the initialization and ISR for Timer 1 used as free running timer. |
| device.h | This file acts as a wrapper to have definitions for the two devices. This code can be used for other devices with no changes or minimal, if any. |
| icp.c | This file consists of the drivers necessary for the ICP module. The functions icp_init and icp_rx can be called respectively, to do initialization and fetch a sample for demodulator. |
| icp.h | This file should be included to use the functions in icp.c. This header file declares the functions defined in icp.c and a required data type icp_sample_t. This type reflects the type used for computing the duty cycle, so it is wide enough to hold values [0:ICP_SCALE]. It also defines the preprocessor symbol ICP_ANALOG, which must be set to 1 to select analog mode and to 0 for digital. |
