Hello all:

I'm a beginner. I want to use the head file in ''C:\Program Files\STMicroelectronics\st7toolset\include\ST72F324J6.h''. But I don't know how do go to use,especial following code: /* System Integrity Control/Status Register */ STVD7_EXTERN volatile unsigned char SICSR @0x2b; define SICSR_WDGRF 0 /* Watchdog Reset Flag */ define SICSR_WDGRF_OR (1 << SICSR_WDGRF) define SICSR_LVDRF 4 /* LVD Reset Flag */ define SICSR_LVDRF_OR (1 << SICSR_LVDRF) define SICSR_AVDF 5 /* Voltage Detector Flag */ define SICSR_AVDF_OR (1 << SICSR_AVDF) define SICSR_AVDIE 6 /* Voltage Detector Interrupt */ define SICSR_AVDIE_OR (1 << SICSR_AVDIE) define SICSR_AVDS 7 /* Voltage Detection Selection */ define SICSR_AVDS_OR (1 << SICSR_AVDS) could anybody help me,please?

Here is an example using the ADC of the ST7Lite09. I hope it is clear enough.

Best regards. /* ---------------------- (c) 2003 STMicroelectronics ------------------- */ /*********************************************************/ /* This program uses the ST7FLITE09.
