USB-to-USB convertor using Adafruit RP2040 USB Host

This is based on Sekigon's Keyboard Quantizer mini-full branch and GongYiLiao's branch supporting the Adafruit RP2040 with USB Host

As GongYiLiao mentioned, the change from Sekigon's original code was 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

GongYiLiao included layouts for:

• Kinesis Advantage MPC (KB500)
• Generic ANSI 104 layout
• Pok3r as an example for 60% keyboard

and added custom DVORAK and other keymaps for those devices.

This distribution is generic, and includes layouts and generic keymaps for :

• Generic ANSI 104 layout under keymaps/ansi
• Razer Tartarus V2 under keymaps/tartarus

How to use this repository

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

git clone https://github.com/whyaaronbailey/adafruitrp2040_usbh.git _your_qmk_repo/keyboards/converter/adafruit_rp2040_usbh
cd _your_qmk_repo/keyboards/converter/adafruit_rp2040_usbh
cd ../../..
make converter/adafruit_rp2040_usbh:_your_choice:uf2 

where _your_choice can be ansi for generic 104-key ANSI keyboard and tartarus for the Razer Tartarus V2

TODO:

• I removed the line "git submodule update --init --recursive" from instructions above because this currently depends on an older fork of Hathach's TinyUSB prior to 2/23/24 commits. The older distribution is included here. Need to update to using current TinyHub commits.
• Add back support for the KA500 and pokr
• Is LED light control possible?
