How to use the library
6.3 OTHER PERIPHERALS
6.3.1 TIMER
TIMERA and TIMERB can both be used simultaneously, depending on the TIMER selected.
You have to define USE_TIMERA and/or USE_TIMERB in ST7lib_config.h. Each function
name in the user manual contains TIMERx where x can be A or B depending on whether it is
for TIMERA or TIMERB. This is also explained in the example given at the end of the TIMER
library.
6.3.2 I/O
You must select the following parameters as per the device package.
#define IO_521_80PIN - Select this for an 80-pin package for ST72F521 device in
ST7lib_config.h file.
#define IO_62_42PIN - Select this for a 42-pin package for ST72F62 device in
ST7lib_config.h file.
#define IO_62_32PIN - Select this for a 32-pin package for ST72F62 device in
ST7lib_config.h file.
If you are using other device packages, you must comment out these declarations in
ST7lib_config.h file.
6.4 MEMORY MODELS
Limitation: in Cosmic, you are not allowed to use the same function in both the main program
and interrupt subroutine. This will give the error of Reentrant function in all memory models ex-
cept mods and modsl.
6.5 PORTING APPLICATIONS FROM LIBRARY VERSION 1.0
Applications can be ported easily from ST7 Library Version 1.0 to ST7 LIbrary Version 2.0 by
making the following changes:
– Change the configuration files st7lib_config.h, default.env, .mak, .prm, and .lkf
– Add device_reg.o in compile list and link list in .mak, .prm and .lkf files
– Remove inclusion of periph_hr.h files from main to access device registers directly
– Replace use of TIMERA, TIMERB macros with USE_TIMERA, USE_TIMERB
– Replace ITC_EXT_ITSensitivity with ITC_ConfigureInterrupt
– Refer to the Release Notes for the list of changes in new version
26/235
data into the transmit buffer, application must call CanInterruptDisable( ) and
CanInterruptRestore( ) services to avoid an interrupt.
