I have a 7 segment connected to my 16F690 with the following connections and configuration: My segment B & C are flickering and I cannot figure out why. Please help:
Code:
Include "modedefs.bas"
DEFINE OSC 8
DEFINE NO_CLRWDT 1
#CONFIG
ifdef PM_USED
device pic16F690, intrc_osc_noclkout, wdt_on, mclr_on, protect_off
else
__config _INTRC_OSC_NOCLKOUT & _WDT_OFF & _MCLRE_OFF & _CP_ON & _PWRTE_ON & _CPD_ON & _BOR_ON & _IESO_OFF & _FCMEN_OFF
endif
