Install the device driver
Based on the previous sections of this document, the following generic example should make clear the main
steps required to install a user implemented device driver:
#include "tcpip.h"
#include "rtos.h"
int huge myDevOpen(DevUserIfaceHandle ifaceHandle);
int huge myDevClose(DevUserIfaceHandle ifaceHandle);
int huge myDevSend(DevUserIfaceHandle ifaceHandle,
unsigned char far * dataPtr,
int dataLength, int flag);
int huge myDevReceive1(DevUserIfaceHandle ifaceHandle,
unsigned char far * far * dataPtr,
int far * dataLength,
DevUserBufferHandle bufferHandle);
int huge myDevGetPhysAddr(DevUserIfaceHandle ifaceHandle,
unsigned char far * physicalAddress);
void interrupt MyDeviceISRHandler(void);
void huge MyReceiveTask(void);
unsigned int recvID; // task ID
unsigned int myrecv_stack[1024]; // stack for receiver task
unsigned char install_done = 0; // waiting flag for receiver task
unsigned int errorCode;
DevUserIfaceHandle MyDevHandle;
TaskDefBlock myrecv_defblock =
{
MyReceiveTask, // task function
{'D','E','V',' '}, // a name: 4 chars
