Reverse Engineering SPI

04 December 2012 - 02:19 PM

Hello,
I have pulled apart a VFD display unit from a dvd player, and i have use a digital analyzer to capture the SPI data stream going to the driver chip from the main board of the dvd player. This chip i have come across in many different models.. So i am wondering if anyone can help me translate from the code captured and the data sheet some roughed out code for talking to the unit by SPI on the netduino..

The driver chip is the PT6315 chip.

Thanks,

Help writing SPI data to screen controller

14 April 2012 - 09:37 AM

Hello, i recently extracted a working VFD unit from a DVD player in the hopes of re-using its VFD chip. i have successively broken out the data control lines to my netduino plus. I have been trying to understand the datasheet and haven't made any progress in controlling the elements of the screen. Attached is my current code, but havent made any progress. Any ideas / code suggestions would be very welcome!
