I have the LPC1227 in 64 pins package lpcxpresso board. I successfully initialised the ssp port. Now I have my spi running.

Next I connected a 20x2 alphanumerical LCD display, that runs on 4,5 to 5,5V. I supply it with 4,5V so the display accepts 0,7VDD for logic one (3,15V in this case). I used a code from this post http://www.lpcware.com/content/forum/help-connecting-lpc1769-lpcxpresso-hd44780-16x2-led-display I reworked it to run on lpc1227 without success

My kindly request is if someone can post here a code that works on lpc1227. I need it to compare with the one I have and try to find the errors (it it's not hardware error). Thanks!

Best regards,
