Problem fixed as far as I can tell: void pic_lullaby(void) { portb = 0xFF; clear_bit(intcon, GIE); set_bit(intcon, RBIE); clear_bit(intcon, RBIF); sleep(); nop(); clear_bit(intcon, RBIF); clear_bit(intcon, RBIE); set_bit(intcon, GIE); } If anyone is able to verify that I'm still doing it right, that...

void go_sleep(void) { unsigned char oldTRISB, dummy; portb = 0; porta = 0; oldTRISB = trisb; trisb = 0xff; clear_bit(intcon, GIE); set_bit(intcon, RBIE); dummy = portb; clear_bit(intcon, RBIF); sleep(); nop(); clear_bit(intcon, RBIF); clear_bit(intcon, RBIE); set_bit(intcon, GIE); trisb = oldTRISB;...

Ah, alright. Thanks a lot!

Sorry to be a nuisance, but my school hasn't provided me with Flowcode and I don't think they're going to give me one of the licenses they have. Is it possible for you to give me a solution that doesn't require Flowcode headers?

It works now, thank you!

Do you mind explaining why those 'checks' for lack of a better term are necessary? Or rather, why mine wouldn't work for more than one write every time I ran the program?

I'm using the Matrix keypad. When I press a button, the corresponding LEDs are supposed to light up. It only does that when I press buttons 1 through 6, 7 to # don't work at all. When I press buttons 1, 2 or 3 the LEDs lit up, but sometimes they're not the right ones, or too many lit up. I'm sorry i...

Does anyone know why it does that?

Does anyone know...?

I changed it, but I think I found a different problem. When I write several things to the EEPROM using the write_eeprom function, it only writes the first... for example if I did: write_eeprom(0, 205); write_eeprom(1, 6); write_eeprom(2, 16); write_eeprom(3, 25); etc... only write_eeprom(0, 205); ge...

The problem is with the splitting up of the large number. The write_eeprom and read_eeprom functions work.

There are no connectors on the keypad to ground it, not like the switch board has.

I'm trying to write a value to the EEPROM, received from button inputs (see my other thread about the Keypad). For now I'm doing it with a switch board... #include <system.h> void setup_hardware(void) { trisb = 0xff; trisa = 0xe0; porta = 0x00; } void write_eeprom(unsigned char address, unsigned cha...

I think I may just be doing it wrong, but I've been breaking my head over it for a while now... I was using this for this configuration/testing strategy: Keypad Board C & Assembly Strategy #include <system.h> void setup_hardware(void) { trisb = 0xF0; trisa = 0xE0; porta = 0x00; } void main(void)...
