Hi: I'm trying to get Myke's 2-wire LCD interface working with a 16F88 and 4x20 LCD. One of the debugging steps is to set _CONFIG1 to INTRC_CLKOUT both in the code and in MPLAB v7.30 configure/configuration bits. But when I put a scope on pin # 15 (RA6) there's no clock out, but there are LEDs blinking etc that make be think the chip is doing something. --snip-- __CONFIG _CONFIG1, _CPD_OFF & _CP_OFF & _DEBUG_OFF & _INTRC_IO & _LVP_OFF & _MCLR_OFF & _PWRTE_OFF & _WDT_OFF & _WRT_PROTECT_OFF & _INTRC_CLKOUT --snip-- org 0 nop nop ; Now set 4 MHz clock bsf OSCCON, IRCF2 bsf OSCCON, IRCF1 bcf OSCCON, IRCF0 nop ; allow some time for oscillator to settle nop --snip-- Any thoughts as the why there's no clock out?
