I am having problems with my LCD,
I am new to this and I got an LCD, I am trying to hook it up to my BS2, it is not serial, I got it from DIGI-KEY and the vendor is Varatronics and the only numbers I see on·the PCB are 16265 R3, but from looking around I assume most LCD's have the same pin info. on the back there are 2 micro's with stickers over them, one is the HD44100FS, and the·other is HD44780A00
The LCD I have is 16x2 and its backlit. its 16 pins, the first two being the backlight, so 14 pins.
when the power is enabled alls I get is the first line full of boxes?, I haven't seen it do much else, I bought a EDE702 Serial interface and still no difference, thought it would make it less confusing to figure out what was wrong. its nice to only have 3 wire interface as·opposed to·regular way.
The EDE702 is working I can turn an LED on and off via the digital output on the EDE702 so I know the chip works with my serout command , but no change on the LCD.. I have been trying to figure it out. driving me nuts
is there an easy way to know if the LCD works? like a test or something?
can anyone help me out!
Thanks in advance
