I use a ST10F276 and Keil. I have configure my ST10 like the ST10F269. Here you can see my configuration. the IT_mesures_analogiques run every 500us.
ADCIC = (14<
SRCP0 = (int)(&ADDAT);
ADCIE = 1;
NB_ADCCH = 1;
ADC_0 = 0;
void IT_adc (void) interrupt ad_trap using registres_ad_trap
{
value_0 = adc_value[NB_ADCCH-1-ADC_0];
}
void IT_mesures_analogiques (void) interrupt t6_trap using registres_t6_trap
{
ADCON = (0x0020|(NB_ADCCH-1)); // Auto scan
// single conversion of NB_ADCCH channel
DSTP0 = _sof_(adc_value);
PECC0 = 0x0200|NB_ADCCH;
ADST = 1; // ADC start bit
}
I have 3 problems :
1.With this configuration I have the ad interrupt but the value_0 = 0 between 0Volt
and 5 Volt.
2.If I add 1 channel :
NB_ADCCH = 2;
ADC_0 = 0;
ADC_0 = 1;
I have i watch dog interrupt and a reset.
3.the 3rd problem is how to do to have an uto scan single conversion of 24 channels (16 ADC + 8 XADC).
Thank you.
