Pintf support with tinyusb / spacemouse emulation

Hi, i'm not sure if this is the right place to ask, but I'm having troubles adapting this code to my needs.
I'm trying to write a program to emulate a spacemouse using an IMU sensor, and to test the program i'd need some debug prints to check the values obtained by the sensor.
I see that you use the function "printf" in your code, but with the tinyusb firmware loaded the pico isn't recognized as a serial device, so i can't read those prints anywhere.
I tryed to follow some examples i found online to enable CDC communication in the descriptor / tusb_config files, but unless i'm doing something wrong (likely) that seems to break the comunication with the spacemouse software.
Did you find a way to receive those prints somehow?
Or do you have a better debugging method to suggest? Thank you.

Support for CAD-MAN USB SpaceMouse

Would be awsm to be able to fit it for the CadMan also!

Do you think i can use the current magellan software with the cad man and be able to at least use the joystick?
How do i need to connect the USB to the PI in this case?

Thank for sharing your Work!

Internal workings

I'm trying to adapt this software to a DIY spacemouse and was wondering if you could elaborate on the internal workings a bit more.
Looking at the source code, descriptors.c seems pretty clear to me. As far as I understand it, it defines the USB manufacturer, model and some other stuff.
My understanding of magellan.c is the following:

• It sets up UART, USB and GPIO pins
• What does this do? 🤔

  magellan-spacemouse/src/magellan.c

  Lines 43 to 44 in acfac3b

  	uint8_t init_buf[] = { '\r', 'v', 'Q', '\r', 'm', '3', '\r' };
  	uart_write_blocking(SERIAL_MOUSE_UART, init_buf, sizeof(init_buf));

• In the infinite loop, it calls tinyusb's tud_task() function to do some USB-related stuff
• It then checks in

  magellan-spacemouse/src/magellan.c

  Line 51 in acfac3b

  if (trans_pending && tud_hid_ready()) {

  magellan-spacemouse/src/magellan.c

  Line 55 in acfac3b

  if (rot_pending && tud_hid_ready()) {

  magellan-spacemouse/src/magellan.c

  Line 59 in acfac3b

  if (buttons_pending && tud_hid_ready()) {

  if a translation, rotation or button press has occured that has to be reported via USB
• After that, it reads a char from UART and that's basically where my understanding stops. Could you therefore please elaborate what this does?
  

  magellan-spacemouse/src/magellan.c

  Lines 66 to 131 in acfac3b

  	buf[idx] = c;
  	idx = (idx + 1) % sizeof(buf);
  	printf("%c", c);
  	if (c == '\r') {
  	printf("\n");
  	switch (buf[0]) {
  	case 'd': {
  	if (idx != 26) {
  	break;
  	}
  	int16_t values[6];
  	for (int i = 0; i < 6; i++) {
  	values[i] = -32768;
  	for (int j = 0; j < 4; j++) {
  	values[i] += (buf[1 + i * 4 + 3 - j] & 0xf) << (4 * j);
  	}
  	printf("%d %d ", i, values[i]);
  	}
  	printf("\n");
  	trans_report[0] = values[0];
  	trans_report[1] = values[2];
  	trans_report[2] = -values[1];
  	rot_report[0] = values[3];
  	rot_report[1] = values[5];
  	rot_report[2] = -values[4];
  	trans_pending = 1;
  	rot_pending = 1;
  	break;
  	}
  	case 'k': {
  	if (idx != 5) {
  	break;
  	}
  	uint16_t buttons = 0;
  	for (int i = 0; i < 3; i++) {
  	buttons |= (buf[1 + i] & 0x0f) << (4 * i);
  	}
  	printf("%04x\n", buttons);
  	memset(buttons_report, 0, sizeof(buttons_report));
  	for (int i = 0; i < 12; i++) {
  	if (buttons & (1 << i)) {
  	buttons_report[button_bits[i] / 8] |= 1 << (button_bits[i] % 8);
  	}
  	}
  	buttons_pending = 1;
  	}
  	default:
  	break;
  	}
  	idx = 0;
  	}
  	}
  	}
  	return 0;
  	}

  
  Thank you in advance 😀

Cheap replacement for the Pololu 23201a Serial Adapter

Hi,

currently, the Pololu 23201a Serial Adapter would cost me about 15€, which would make this project more expensive than the old Spacemouse itself.

Is it possible to replace it with a cheaper alternative, like the Waveshare RS232 Board, or is there anything that specifically requires the 23201a?

Thank you!

Request to create firmware for space mouse classic usb

Hello. I assembled hid-remapper for your project on one raspberry pi pico board. Tried connecting my old Space Mouse Classic USB controller. On some computers, the Space Mouse Classic USB is not installed correctly. I tried with the help of your device to solve this problem. Space Mouse certainly didn't work with hid-remapper. I want to ask you to make Space Mouse Compact emulation firmware for Space Mouse Classic USB based on the hid-remapper board. Ready to become a firmware tester.
