6 Typical Application

This is the typical application introduction.

6.1 HW Design

In this application, we will test the operational amplifier in the MB95F430K. The HW is designed
as below. The R1, R2, R3 is used in open-loop amplifier.

6.2 Sample Code

void main(void)
Return : none.
Parameters : none;
Description : system main programm.
Example : main();
void main(void)
{
__DI();
__set_il(3);
InitIrqLevels();
WDTH =0xA5;//Disable WTG
WDTL =0x96;
WATR =0xEE;
SYCC =0xF0;//Main Clock
SYCC2=0xF4;//Main Clock
SYSC =0xBC;//BUZZ(P01)
SYSC2 =0x02;//PPG(P73),Disable I2C
while(!STBC_MRDY);
__EI();
AmpOpenLoop();
AmpCloseLoop();
}
