Mac OS X USB LCD Kit LCDproc code

LCDproc

The source will hopefully be incorporated into LCDproc and I should have a compiled download available shortly.

THe default set up is for winamp wiring, but the MAC OS X USB LCD Kit is wired a bit differently. Make sure to uncomment:
//#define USS720_MAC_USB_LCD_KIT_WIRING 1
to enable the proper wiring for the kit.

Update: 8/10/2008

The hd44780-USS720 driver code has been incorporated into LCDproc. I hope to have a compiled version available for download as soon as possible.

Nice job. I want to test out the uss720 code, but I have a 16 pin HD44780, and I'm not sure how to get the +5V for the backlight. Is there a pin on the Centronics pin that's a dedicated +5V? How did you deal with the backlight in your LCD kits?

I read your old post at Pin out post. How did you determine to merge pin 13 and 14 together? Did you put diodes before combining the pins?

No diodes, it just gives more power. I know it looks horrible, but it works and I haven't have a problem with it. At worst, it could cause a problem with the adapter, but I have had it running for months without a problem. There may be diodes in the adapter.

As for the 5 volts, you could get it from the usb, but not the Centronics connector.
