MK2 LPT port, SPI progrmming issue
Posted: Sat Feb 11, 2017 11:56 pm
I'm trying to flash firmware on an HC05 bluetooth module.
The Qualcomm software uses the port in ECP, and "legacy plug and play" enabled and hooking up mosi, miso, csb, and clk into the parallel port of a computer. I'm trying to use my 29 mk2 to do so, and it's having an issue I can't figure out. I'm using 1200/2200 voltage dividers to drop signals to 3.3 and a 5v usb power supply. I'm %98 sure I have the physical connections correct.
Is the paralell port in the 29's fully functional? or is there a known limitation for something like this?
Thanks, guys!
