Hallo,
Habe ein Projekt mit einem PIC 18F2585.
Die Schaltung und die Software funktioniert im Prinzip.
Nur dass der Pic in genau gleichen Zeitabständen selbsttätig einen Reset macht.
Auch bei einem kleinen Testprogram geschieht dies:
#include "D:\Projeckte\OpenBMS\test.h"
int32 c;
void main()
{
setup_adc_ports(AN0_TO_AN9|VSS_VREF);
setup_adc(ADC_CLOCK_DIV_32|ADC_TAD_MUL_20);
setup_spi(FALSE);
setup_wdt(WDT_OFF);
setup_timer_0(RTCC_INTERNAL);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
setup_vref(FALSE);
setup_oscillator(False);
// TODO: USER CODE!!
c=0;
output_high(PIN_B0);
while(1)
{
c++;
output_high(PIN_C5);
printf("+%ld\r\n",c);
delay_ms(500);
output_low(PIN_C5);
delay_ms(500);
}
}
Die Datei:"D:\Projeckte\OpenBMS\test.h"
