Library Structure
St7lib_config.h is divided into two major sections:
4.2.1 User part of the ST7lib_config.h
– You can customize this portion to your application requirement
– You can define your own labels and macros here
– You can change the CPU clock value (default is 8MHz)
– For the ST72F264 device you can select whether to use Port C as ei0 or ei1
– The target ST7 device file (st72xxx_periph.h) has to be included in this file
Note: An error message “No Valid ST7 MCU Configuration” will be generated by the compiler
if no device file has been included.
4.2.2 Non-User part of the ST7lib_config.h
This part contains the labels for METROWERKS and COSMIC compilers. It contains the com-
piler definitions as follows:
#if (defined __HIWARE__ | defined __MWERKS__ )
#define _HIWARE_
#else
#ifdef __CSMC__
#define _COSMIC_
#else #error “Unsupported Compiler!”
/* Compiler defines not found */
#endif
#endif
The labels __MWERKS__ (__HIWARE__) and __CSMC__ are automatically set by the
Metrowerks and cosmic compilers respectively. If none of these two compilers are selected
then an error message “Unsupported Compiler!” appears on the debugger window.
Macros definitions in ST7lib_config.h:
ST7lib_Config.h file also contains a list of macros. They are as follows.
1. EnableInterrupts: You can use this macro to reset the interrupt mask, this macro is equiva-
lent to the RIM instruction in assembly.
2. Nop: No operation. This is equivalent to the nop instruction in assembly
3. DisableInterrupts: You can use this macro to set the interrupt mask, this macro is equivalent
to the SIM instruction in assembly.
4. WaitforInterrupt: This is equivalent to the “wfi” instruction in assembly.
