hi all, i have this project to do and it was working fine until i added "adc_read", i don't get any error on Mikroc pro after building but in practice it's not working. please can you help me to figure out the problem. i'm using pic18f4520 with lcd, keypad and a sensor. unsigned long kp=0,mpres=0, wei=0, mwei=0, res=0, count=0, x=0;
Hi, All I wants to interface a 2*16 lcd with 8bit mode in assembly language in which the external crystal is 20Mhz in where I have already try but still there is no output, the code samples are below mentioned. So, any one can guide . #INCLUDE R1 EQU 81H R2 EQU 82H lcd_DATA EQU PORTB lcd_CTRL EQU PORTD
Hi I want to interface Glcd with pic18f4520 I am using PIC18 basic simulator Can anyone give the exact code to draw a sinusoidal wave on the Glcd with minimum numbers of variables and loops? Thanks
Hello dears, This website is such a magnificent job. Great effort, in a smart way with interactions of great experienced members. I`m doing a small project, concerning automation/control/monitoring about a green-house. I`m using a pic18f4520. I`m coding in Assembly. I'm using as output an 2*40 lcd (LMB402CFC): as an interface for the user.

I'm using TC1602A lcd and pic18f4520 microchip. the lcd display square black box when I tried to display something. When i connect 5V from the fixed 5v power supply, it can display what I want. Can anyone tell me what wrong with it ? I tried to use potential meter to reduce the current but it burned.
Hi I have problem in pic18f4520 lcd DISPLAY. (1) The physical set up with PCI18F4520 and lcd is using PORTDbits.RD4 and RD5 as RS and Enable. RW pin is connected to ground. (2) I use MPLAB V8.9 and C18 compiler. 4-bit mode lcd data using PORTD. (3) The problem is I use PICkit2 to program and use Vdd from kit2. It (...)
Can anyone help me check whether this code is correct anot ? //Define .hex file// #include #include #include //Define Configuration bits// #pragma config OSC = INTIO67 //Set to use internal oscillator // No external oscillator #pragma config WDT = OFF //Turn off watchdog timer #pragma config LV
Then all I can think is that you have a faulty canned oscillator, faulty board or faulty pic18f4520. Can't think of anything else to try.
i want to measure the oxygen rate of person using pulse oximeter sensor and display it in lcd using pic giving input in the form of voltage to pic controller.According to the voltage level,i want to vary display in maximum voltage will be 440mv and min will be 1/0mv.i want to display 99% if my voltage is 440mv else 1% for

I'm just curious why it's like this. I though I can keep my another pic18f4520 for backup purpose. Is it possible for you to try the PIC which causes you problems on another hardware? or with some another programm? I know, you can say your problem is solved, but you can check this if you want to go in deep why tha

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
Hello, Does anyone know how to set time in RTC? We're using pic18f4520 in MikroC Pro. We tried the code below but the output in our lcd is one that is counting very fast that we cannot see the data anymore. Please help me on this endeavor. Any help is greatly appreciated. Thank you. char seconds, minutes, hours, day, month, year; // Glob
