Hi All,
I am working on CS89712 Arm processor with ecos2.1.
I am trying to get the touch panel to work. I am having a problem. Every
thing seems to work at least the hardware is working after testing with
scope all signals are there. Clock signal is correct CS is correct I can
write to the chip ADC7846 chip no problem and the chip returns data. Can
not prove that the data is correct.
My problem is that the register always returns 0xFFFF. No matter where on
the panel I touch. The signal on the scope does changes. Could anyone help
me or tell me what to look for. Your help in this matter is greatly
appreciated.
Thanks in Advance
Ray B.
