Hi again, I am using a Spider with a T35 for debugging purposes. Black screen with scrolling text outputting information as the system is running. Currently the T35 is occupying 4 sockets RGBT and I am thinking if it would be possible to disconnect some of them, when the required graphics is so simple.
And if disconnecting connections, how to inform the driver, and leave them for other purposes?
I would assume that as the connections to the LCD are outputs only, you could boot up the devices headless after you had completed all the debugging?
Not sure about reconfiguring but if you recall, the default with the latest firmware is for the LCD to be disabled. I would assume at this point you could use the IO connections as their alternative GPIO.
You could hardwire the shutdown pin on the Green socket of the T35. Not sure if it needs to be tied high or low (it’s used to turn on and off the back-light). Just cut a gadgeteer cable in two and solder the correct wires together. This should definitely get the display running.
It’s probably first worth trying to see if you can manually change the Green D0 to D5 Pins as regular outputs without corrupting the other colours on the display. Changing these should globally adjust the green level of all pixels on the display.
