Hello, I have Haiku on my laptops (System 76, Dell and HP). All have a common fault, they have no serial or parallel ports that I can program to drive my own hardware designs.
Years ago there was a USB-PIO design shown, is it still available for Haiku? Or something like it? If so how would I access it in my programs?
Alternatively, I could try modifing a USB keyboard as an input but I don’t know the scan rate for keyboards so I don’t know how fast I can input data yet.
Also there are USB joysticks, do those work with Haiku yet? If yes I can buy one tomorrow, again do you know how fast the joystick is scanned in?
Lastly, looking at the USB updates there is something called a USB Sensor Hub, but so far the ones I found on the internet have a slow scan rate.
For my purposes I need to do 1000 samples per second, I don’t think the keyboard mod will work that fast, can anyone help point me in the right direction.
