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 (...)
Hi! I am working on a project that is capable of moving a motor (in a time based manner) every after 30 minutes. The time will be based on an RTC in such a way that when I turn on the system, it looks at the time in the RTC to know which position the motor should be in and then after 30 minutes, it will move to the next position again. Codes below
Hi guys, I'm have try implement the code from mikroC example : lcd. I just see the lcd just showed first row with black dot nothing else just like without programming into it.

First of all you have missed something i.e.. the visual part. I understood it like this ,your system is going to take a file name from user and create one file with that name , then again it is going to take user input and save the data in that file. That file may be stored in a sd card or in any other memory that?s not the
Does anyone here ever write a code for power saving mode for pic18f4520 ? I'm trying to say is, in power saving mode; the PIC is in "IDLE" mode, which also turn off the lcd also, so that the consumption of current flow from power source / battery will not be that much. Regards Linspire
