can you please provide some test firmware?

[YCF]

First of all, thank you very much for the design. At present I was in trouble, I have welded the receiver and keyboard, it does not work properly. The two modules and the pro micro I have flashed.

But,because the PCB does not some indicate working status leds, so we do not know whether the wireless module is working properly. I hope you can provide some basic wireless test firmware, I can think of is:

1. Receiver Test firmware: After the power is on, send a button keep pressing and releasing to Pro micro , so we can know that the receiver module is working properly.

2. Keyboard Test firmware: Send the letter 'A'( S6 ?) to the receiver repeat, so we can know that the wireless part of the receiver and keyboard is working properly.

Now I am facing a non-working mitosis, and I totally do not know how to fix it.

Maybe a blink firework? At the keyboard part every mx switch is an io,so we can connect a led to the mx switch foot to test it.

This is a really great idea. Pester me if it's not up by next weekend. :)

any chance you can publish that 'blinky' sketch, YFC?

@TyberiusPrime Here is the hex files: mitosis_let_test.zip

I modified the mitosis PCB, so some led position may be different, but each led should be bright.

PS: maybe left is right! ;-P

@YCF cool! Your blink test works for me. Could you please also build something to test receiver and its module? I haven't soldered any leds to receiver, because I have no PLCC-4 but I tried individual leds and they don't seem to light up at all. I'm not getting any response from it and keyboard doesn't work, and I have no idea why. Pro Micro recognizes as HID keyboard, receiver's and left/right modules respond to openOCD but it doesn't send any keystrokes. Could you upload all the firmwares you're currently using including QMK? Maybe I've just built it wrong. Maybe YJ-14015 has different RX/TX pins or I have faulty PCB but for the love of god I can't make it work. I've asked @reversebias to upload his QMK firmware as well.

P.S. could you please share the source of that blink test? I've soldered keyboard led to the right half (PIN 17) but I can't turn it on using mitosis toolchain. I'm trying:

    nrf_gpio_cfg_output(LED_PIN);
    nrf_gpio_pin_set(LED_PIN);
    // Main loop

...but it doesn't light up. I've tried to build SDK11 rtc samples with IAR (edited boards.h) and upload it the same way, they blink just fine.

Upd: IT FINALLY WORKS. I had to re-create and rebuild the entire project with IAR. Had to #define CLOCK_ENABLED 1 and #define RTC0_ENABLED 1 for the receiver otherwise it doesn't compile there. I've also added LED suport for the keyboard halves (it just blinks a couple of times on power up). See my fork (devel branch).

EDIT: This is now fixed. I had a floating RX pin on the pro micro

I'm having similar issues to @joric's post. All chips are programming ok but the keyboard as a whole isn't working. I've no idea how to debug it with OpenOCD so it's a total black box to me

I'd appreciate advice on how to:

• Get log messages from the chip
• Simulate keypresses on the receiver

Thanks

I just realised this issue is closed so people wouldn't have got notifications

Pinging @YCF @reversebias @joric (hope that's not spammy)

Hey man! I managed to solve it with #7. You can also browse https://github.com/joric/mitosis/tree/devel there are precompiled binaries I used.
