hi, i am currently working on a project using pic18f4520 in MikroC. it has to read the LM35s connected to each of the 6 ADC channels (AN0-AN5). also, we wanted to display those values in the lcd. please see code below. but the output in the lcd shows the same value for all of the ADC channels even if the LM35 is exposed to different (...)
Hi all, I'm working on a project that makes use of RTC and the pic18f4520's ADC module on MikroC. The code that I drafted (please see below) builds in MikroC but doesn't work on breadboard. The RTC counts up but does not have a display in the lcd the whole time. Instead, it follows the delay of the ADC so the output in the lcd only (...)
