Ik krijg op een 16f88 poort B1 niet werkend als digitale uitgang.
Wat doe ik verkeerd ?
pic basic code:
Device 16F88

@__CONFIG _CONFIG1, CP_OFF & CCP1_RB0 & DEBUG_OFF & WRT_PROTECT_OFF & CPD_OFF & LVP_OFF & BODEN_ON & MCLR_OFF & PWRTE_ON & WDT_OFF & INTRC_IO
@__CONFIG _CONFIG2, IESO_OFF & FCMEN_OFF

; OSCCON Oscillator Control Register:

; bit 6-4: frequency (IRCF):
; 110: 4 mhz
; 111: 8 mhz
; bit 3: OSTS: 1 (run from primary system clock), 0 (run from T1OSC or INTRC as a secondary system clock)

; Allow ?? us sample time, typical is 50-100, this allows
; adequate charge time without losing too much conversion speed.
; According to page 119 of the 16F88 datasheet, typical AD
; conversion takes 11-12 TAD. Using FRC nets an average of 4
; us per TAD. A minimum of 48 us is therefore recommended. But
; TAD time of FRC varies between 2-6 us! So worst-case, conversion
; takes 12 * 6 = 72 us. To be sure, use ADIN_STIME 75.
