USB-to-USB convertor using Adafruit RP2040 USB Host

This is based on Sekigon's Keyboard Quantizer mini-full branch

The change made here is to specify DP+ Pin as 16 (thus DP- is 17) and the 5V pin (18) in c1_usbh.c:

// Initialize USB host stack on core1
void c1_usbh(void) {
    pio_usb_configuration_t pio_cfg = PIO_USB_DEFAULT_CONFIG;
    pio_cfg.pin_dp                  = 16;
    // pio_cfg.extra_error_retry_count = 10;
    pio_cfg.skip_alarm_pool         = true;
    tuh_configure(1, TUH_CFGID_RPI_PIO_USB_CONFIGURATION, &pio_cfg);

    gpio_init(18);
    gpio_set_dir(18, GPIO_OUT);
    gpio_put(18, 1);

    tuh_init(1);
    c1_start_timer();
}

Available keymaps

I made some layouts in info.json and corresponding keymap.c for DVORAK typist:

Kinesis Advantage MPC (KB500) under keymaps/ka500
Generic ANSI 104 layout under keymaps/ansi, test on Topre Type Heaven
Pok3r as an example for 60% keyboard

How to use this repository

After setup your qmk envorinment, clone this repository to keyboards/converter then run

git clone https://github.com/GongYiLiao/qmk_AdaFruitRp2040USBH.git _your_qmk_repo/keyboards/converter/adafruit_rp2040_usbh
cd _your_qmk_repo/keyboards/converter/adafruit_rp2040_usbh
git submodule update --init --recursive
cd ../../..
make converter/adafruit_rp2040_usbh:_your_choice:uf2

where _your_choice can be ka500 for Kinesis Advantage MPC (KB500), ansi for generic 104-key ANSI keyboard and pok3r if you have a Pok3r keyboard
