2.7.5 Generating Code With Applilet

Once the various dialog boxes are set up, select the “Generate code” option. Applilet will show the

peripherals and functions to be generated, and allows you to select a directory to store the source

code.

When the “Generate” button is pressed, Applilet creates the code in several C-language source files

(extension .c), C header files (extension .h), and assembly language source and header files

(extensions .s and .inc), and shows the list of files created in a dialog box.

To support the initial startup code, Applilet generates assembly source file crte.s. For clock

initialization, Applilet generates system.inc and system.s. The SystemInit() function is generated in

systeminit.c.

To support the CSI00 peripheral, Applilet generates serial.h, serial.c, and serial_user.c. See details

on these files below.

To support the Timer00 peripheral, Applilet generates timer.h, timer.c and timer_user.c.

To support I/O port initialization, Applilet generates port.h and port.c.

Several other files are generated, including a main.c file with a blank main function. Applilet also

generates a link directive file, 850.dir, to control the linking process.

2.7.6 Applilet-Generated Files

For the demonstration program, Applilet generated several source files. The files and their

functions are shown below.

Table 6. Applilet-Generated Source File

File Function

Macrodriver.h General header file for Applilet-generated programs

Crte.s Reset vector, program startup code

System.inc Assembly-language header for system.s

System.s Assembly source for Clock_Init() routine

System_user.s Empty file (would contain code for System interrupt if used)

Systeminit.c SystemInit() routine for peripheral initialization

Main.c The main program routine

Inttab.s Interrupt vectors with RETI for unused interrupts

Port.h Header file defining initial port states

Port.c Port_Init() routine

Serial.h Header file for serial.c

Serial.c CSI00 functions generated by Applilet

Serial_user.c Callback functions for UART1 and CSI00, for user code
