Re: 18F25K22 Help
The current code is written as such: Turn on each LED in sequence and leave them on until the button is pressed. It is a pull down input. When the button is pressed, turn off all the LEDs and repeat the sequence.Code:;----[18F25K22 Hardware Configuration]------------------------------------------ #IF __PROCESSOR__ = "18F25K22" #DEFINE MCU_FOUND 1 #CONFIG CONFIG FOSC = INTIO67 ; Internal oscillator block CONFIG PLLCFG = OFF ; Oscillator used directly CONFIG PRICLKEN = ON ; Primary clock can be disabled by software CONFIG FCMEN = OFF ; Fail-Safe Clock Monitor disabled CONFIG IESO = OFF ; Oscillator Switchover mode disabled CONFIG PWRTEN = OFF ; Power up timer disabled CONFIG BOREN = SBORDIS ; Brown-out Reset enabled in hardware only (SBOREN is disabled) CONFIG BORV = 190 ; VBOR set to 1.90 V nominal CONFIG WDTEN = ON ; WDT is always enabled.

Right now, LED1 turns on and then when LED2 goes to turn on, LED1 turns off. LEDs 2-4 sequence on and stay on, but LED1 stays off. On the first run, the LEDs turn on and stay on until the button is pressed. After the initial press, the LEDs turn on in sequence (except for LED1) and once LED4 is lit, they all turn off and the sequence in repeated.
Can't figure it out unless it's because of my pins not all being set to digital. I'm asking for help on what the proper code is for setting them all to digital. I keep finding posts where people say read the datasheet. I've read the datasheet and I've entered what I think it is telling me for how to set the pins to all digital. I'm now asking for help.
