Hi,
at first sorry for my english. I´m a student from germany and this is my first project with a microcontroller.
I´m using a DEVKIT-S12ZVC Board (9S12ZVCA192 microcontroller). There is only a #include for "peripheral declarations" in CodeWarrior. Is there a library containing ready functions which can be used for example setting the registers? Normally you have to implement a code like this on yourself:
void ADC_init(void){
ADC0CTL_0 = 0x0D; /*Dual Access mode and trigger mode selected */
ADC0CTL_1 = 0x00; /* Single command and result value list */
ADC0TIM = 0x0F; /*No prescaler selected */\
ADC0FMT = 0x82; /* Left justified and 10 bit resolution */
/* ADC0 Command & Result Base Pointers */
ADC0CBP_0 = (unsigned char)(((long)adc0_cmdlist) >> 16);
ADC0CBP_1 = (unsigned char)(((long)adc0_cmdlist) >> 8);
ADC0CBP_2 = (unsigned char)((long)adc0_cmdlist);
// ADC0 Result Base Pointer
ADC0RBP_0 = (unsigned char)(((long)adc0_results) >> 16);
ADC0RBP_1 = (unsigned char)(((long)adc0_results) >> 8);
ADC0RBP_2 = (unsigned char)((long)adc0_results);
ADC0CTL_0_ADC_EN= 1; /*Enables the ADC */
}
unsigned int ADC_read(unsigned int channel){
adc0_cmdlist[0][1] = 0xC0|channel;
ADC0FLWCTL_RSTA = 1; // Restart Event
while(0x00 == ADC0CONIF){} //wait until conversion is complete
ADC0CONIF = ADC0CONIF;//clear flag
return adc0_results[0];
}
unsigned int ADC_read_PGA(unsigned int channel, unsigned char PGA_in){
adc0_cmdlist[0][0] = 0xC0|(PGA_in<<4);
adc0_cmdlist[0][1] = 0xC0|channel;
ADC0FLWCTL_RSTA = 1; // Restart Event
while(0x00 == ADC0CONIF){} //wait until conversion is complete
ADC0CONIF = ADC0CONIF;//clear flag
return adc0_results[0];
}
Can I download or add a library which includes standards like the example?
Thank you in advane.
Kind regards
Christina
