Sorry, never mind, I found where you turn on RD7..Had to make it =0 to turn on the decimal point. So I am having issues trying to get the code to compile. Lcd_Write_String(LCD Library fr); { #pragma config BOREN = OFF Make sure that your compiler is working fine void Lcd_Port(char a) This would do better if posted the "MicroControllers" forum. Submitted by mojtaba on Sun, 07/18/2021 - 14:04, Hi dear Aswinth Raj, in the funtion below, unsigned int ADC_Read(unsigned char channel). Dont forget to make that changes in program too. This connection can be made on a breadboard. Since we have already learnt about ADCs and LCD interfacing, I will further explain the code to save and retrieve data from EEPROM. That is due to delay limit. Erasing Target If else analogRead is between 376 and 500 then lcd.print("high"), ladan: #define RS RC0 How do I choose the ACQT bits? You might need to make minor changes in the address in library. ^ //Lcd_Set_Cursor(1,1); Lcd_Cmd(z); Just remember that microcontroller is operating at high speed in the range of MHz and we are viewing LCD with our eyes. By varying the pot, a variable voltage will be sent to the MCU which will be read by the ADC module and displayed on the 7-segment display Module. we study electrical-electronic engineer so it is not so easy for us. It is not an error of above program. main.c:5:12: note: expanded from macro D4 Mine is reading fine, but no decimal point. To retrieve a data that is already stored in EEPROM and save it to a variable the following line of code can be used. I am using PIC18F4685 and trying to understand ADC with this microcontroller (I just started a week ago with microcontroller). D7 = 1; Hi again, I have successfully modified my code, and thankfully I am seeing a better display on my LCD now. Now I see how this routine is just testing to see which bits are set in a and sets the corresponding ones for the LCD! } Please give the details of the problem you are facing. Hello, the above library is for XC8 compiler.. not for XC18.. they are different.. PORTD=0X00; This code is ok with a PIC16F1619 microcontroller ? I have changed all of the RDs to RBs, as my chip doesnt have port D available. If you are seeing 255, it means you are reading only 8-bits of A/D conversion. When I talk about.
