Graphic LCDs / C12864WC - Capacitors
« on: July 31, 2014, 12:12:01 AM »
Hi,

I purchased this COG LCD (http://www.newhavendisplay.com/nhdc12864wcfswfbw3v3-p-4048.html) and the FFC30 adapter board (http://www.newhavendisplay.com/nhdffc30-p-2477.html) with the hope that I can get it connected to a breadboard and arduino. This is my first time working with a COG LCD and I am not sure what capacitors I should use. Per the data sheet (http://www.newhavendisplay.com/specs/NHD-C12864WC-FSW-FBW-3V3.pdf), it states 1uF and 1uF-2.2uF caps are required. I did a search on digikey, jameco, radioshack and other sites and find hundreds of options matching this criteria. I ended up ordering these:

https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=81509
https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=33736

With everything hooked up, the display is not working right. It will flash 'hello world' and quickly dissolve away. I suspect the capacitors, as this is the piece I know the least about.

Could you verify these are ok to use or suggest what I should be using with this display?

Regards,
Brad
