@CHIP-RTOS C Library V2.00 - Fossil API


fossil_user_callback

Install a Fossil User Callback Function. The User Callback function will be called when a fossil event occurs.

void fossil_user_callback ( int port,
                            FOSSIL_USER_CALLBACK pfFossUCB );

Parameters

port

Port specifier:   FOSSIL_EXT = 0 for EXT port,   FOSSIL_COM = 1 for COM port

pfFossUCB

Pointer to Fossil User CallBack function

Comments

This call installs a User callback function for the specified serial port. The Callback function must be very short! Long fossil callback functions could be lead to characters losing. To use the fossil callback functions you have to switch the serial port into the IRQ Mode (use CHIP.INI to do that). In DMA Mode the callback functions does not work!

The callback function must be declared like the function below:
fossil_event_t *(huge my_fossil_callback)( fossil_event_t *e )
