LPC2148 adc and lcd display

[dee12]

hello,

i am working on LPC2148 . so far, i have tried out blinky and lcd program on my evaluation board. i want to do adc conversion and display the digital value on lcd. my lcd code works individually but when i add lcd functions to adc code, there is no display when i run it. can it be an issue with delay? any help appreciated.

hello,

i followed your advice and slowed down the adc process.
the code seems to be working fine when i run it in my KEIL simulator. it is not running on LPC2148.
