Yes, you just have to add '+' prefixed lines.
What's you file name? What command do you compile it with?

Port PB5 is used for Instert LED and PB6 for CapsLock LED. You will have to change only LED_ON and  LED_OFF.

Ya i understand so i tried with both LED on first. However it gives no response on my own compiled hex.

This is the full codes of my keymap.c

Not really sure what is wrong as my coding knowledge is very limited..

That patche is for TMK and won't work with QMK. You have to port the code to QMK.
I think you can consult with its document and comunity.

Understand and thanks! Will explore that my own :)

hi hasu.  thank you for providing the schematics to make my own controller.  i pretty much copied your controller but i'm using different pins.  i kind of understand some of the TMK code, but am at a loss on how to assign the pins for the rows and columns.  am i on the right track with the following code?

Code: [Select]
* Pin configuration for ATMega32U4
 *
 * Row:     PB6, PF7, PB5, PB7(~EN)
 * Col:     PF6, PB4, PF5, PD7(Z5 ~EN), PF4(Z4 ~EN)
 * Key:     PD4(pull-uped)
 * Hys:     PF0
 */

static inline void KEY_ENABLE(void) { (PORTB &= ~(1<<7)); }
static inline void KEY_UNABLE(void) { (PORTB |= (1<<7)); }
static inline bool KEY_STATE(void) { return (PIND & (1<<4)); }
static incline void KEY_HYS_ON(void) {PORTF |= (1<<0)); }
static inline void KEY_HYS_OFF(void) { (PORTF &= ~(1<<0)); }
static inline void KEY_INIT(void)
{
    /* Col */
    DDRB  |=  0x10;
    DDRD  |=  0x80;
    DDRF  |=  0x70;
    /* Key: input with pull-up */
    DDRD  &= ~(1<<4);
    PORTD |=  (1<<4);
    /* Hys */
    DDRF  |=  (1<<0);
    /* Row */
    DDRB  |=  0xE0;
    DDRF  |=  0x80;

    KEY_UNABLE();
    KEY_HYS_OFF();
}

if the above is correct, how would i set the row and col in the next few lines?  thank you for all your work!

You looks so.

I can't say if your code is correct totally, because I don't have time enough to check it closely and don't know exact your pin configuration.
You can share your circuit schematic and pics of pcb here to get further help. And what's your problem exactly? Your code didn't work?

Also share your entire code on github(or other site), it would be useful for the community.

You may want to check fc660c.c and read the first post to understand how FC660C controller scans its key matrix. I'd reccomend to take time to do this.
https://github.com/tmk/tmk_keyboard/tree/master/keyboard/fc660c

And note that you can use `xprintf()` to debug your code. It is extremely useful when tweaking code.

Hi hasu - thank you for taking a look.

I think I understand how to assign the row and column pins, but I'm not sure how to set them if that makes sense?  Particularly the SET_ROW and SET_COL lines:

Code: [Select]
#ifndef FC660C_H
#define FC660C_H

#include <stdint.h>
#include <stdbool.h>
#include <avr/io.h>
#include <avr/interrupt.h>
#include <util/delay.h>
#include "timer.h"
#include "unimap.h"


// Timer resolution check
#if (1000000/TIMER_RAW_FREQ > 20)
#   error "Timer resolution(>20us) is not enough for HHKB matrix scan tweak on V-USB."
#endif


/*
 * Pin configuration for ATMega32U4
 *
 * Row:     PB5, PB6, PB7(~EN), PF7
 * Col:     PF4(Z4 ~EN), PF5, PF6, PD7(Z5 ~EN), PF5
 * Key:     PD4(pull-uped)
 * Hys:     PF0
 */
static inline void KEY_ENABLE(void) { (PORTD &= ~(1<<7)); }
static inline void KEY_UNABLE(void) { (PORTD |=  (1<<7)); }
static inline bool KEY_STATE(void) { return (PINC & (1<<6)); }
static inline void KEY_HYS_ON(void) { (PORTC |=  (1<<7)); }
static inline void KEY_HYS_OFF(void) { (PORTC &= ~(1<<7)); }
static inline void KEY_INIT(void)
{
     /* Col */
    DDRB  |=  0x10;
    DDRD  |=  0x80;
    DDRF  |=  0x70;
    /* Key: input with pull-up */
    DDRD  &= ~(1<<4);
    PORTD |=  (1<<4);
    /* Hys */
    DDRF  |=  (1<<0);
    /* Row */
    DDRB  |=  0xE0;
    DDRF  |=  0x80;

    KEY_UNABLE();
    KEY_HYS_OFF();
}
static inline void SET_ROW(uint8_t ROW)
{
    // set row with unabling key
    PORTD = (PORTD & 0x0F) | (1<<7) | ((ROW & 0x07) << 4);
}
static inline void SET_COL(uint8_t COL)
{
    //         |PD7(Z5 ~EN)|PF4(Z4 ~EN)
    // --------|-----------|-----------
    // Col:0-7 |high       |low
    // Col:8-F |low        |high
    PORTB = (PORTB & 0xE0) | ((COL & 0x08) ? 1<<4 : 1<<3) | (COL & 0x07);
}

Thank you for your help!

I can't remember the details without traversing schematic and my code again but I think the macros just drive matrix lines one by one with multiplexers(4051, 138).
If you read schematic and datasheets closely  it would be straight, no tricks there.

Nice pcb layout! Btw, what is J3 connector for?

I think I understand, but I'm quite new to the firmware coding aspect of keyboards so I'll have to keep playing around with it.  The J3 connector is for a companion MX/ALPS PCB that fits in the FC660C case.  It uses an additional 5 unused pins from the atmega for the PCB matrix (firmware for mechanical switches are way easier than capacitance :D).  So users have the choice of flashing different firmware based on what PCB they're using.

It works using the OEM cable, but I need to source some DF14 cable harnesses that are long enough to reach the PCB connector.
