There is a sample program in my Unicorn manual on my site for a 16x2 lcd on a 18f4550, should be easy enough to convert.
hi!!! The only changes i made are as below #define RTC_SDA PIN_B0 #define RTC_SCL PIN_B1 and this is codes #include <18f4550.h> #fuses HSPLL,USBDIV,PLL5,CPUDIV1,VREGEN,NOWDT,NOPROTECT,NOLVP #use delay(clock=48000000) //,RESTART_WDT #include #include <lcd.c> #define lcd_RS PIN_D0 #define (...)
I have been googling for a long time, I found almost all other libraries (for AVR, non-graphic lcd, Basic, ...) but couldn't find one for Microchip C18 (with 18f4550). Can you please tell me a way to find them or simply send them to me. I only need two files like "glcd.h" and "glcd.c". If you want to send via mail feel (...)
PIC18F2550 or 18f4550 both have USB slave hardware built in. The easy way is use an FT232R USB to RS232 (TTL) IC.
hi I have to build a board with 18f4550 and my device have to get information from pc and show it on lcd or etc.. but the problem is that, despite my researches, I found nothing about it. I know pic assembly, and visual basic6 ( I can use pic basic pro) , I've tried Easy Hid but that program does only connection, I don't know how to send informati
Hello everybody..... I am facing some problem to interface the 16*2 lcd (JHD 162A) with PIC 18f4550. I am using mikroC compiler. Bellow is the circuit connection and program. Anybody please check it and help me about this. The system is not working. ================= Connection pin ================= lcd ---------------
That 12" 800x600 display panel requires complex display driver circuitry. It cannot be connected directly to a 18f4550
Hi For All First of all excuse me about my English. I want to show file or folder name of flash memory on lcd character but I don't know how to Start and I doubt this project is Possible or no?! Your Sincerely SAEID

i have been assigned a micro controller project involving 18f4550. My project is to log data (temperature, Humidity, & light Intensity) on memory card. I am using ccs Compiler (PIC C) for programming, but every time i try to initialize the card it give error. Any Help regarding this will be highly appreciated. Tanks in advance.
Hai, Using MIkroC How to detect 18f4550 as usb device in PC. Give me some tricks for programming. My aim is transfer some data from pic to pc through usb.
Can anyone give some basic ADD and MINUS calculator source code to me? Or anything relate with simple calculator might help? pls, i needed it . thk for helping, *** bless
hello; am writing a code of hid connection between PC and pic18f4550 threw USB when i start simulation on ISIS without connecting in real USB it's simulation with hyperterminal i get my usb detect but i can't found it so i wanna know if it's normal or not and if i connect my pic threw usb in real it will work or no? thank you in advance [url
hello , am connecting a reset button to my MRCL pin of pic 18f4550 but when i click the button and every thing crash down no more right data on lcd, no more LED blinking!!!!!!! and those message appear on the ISIS simulation PC=0x0000. §MCLR§ is low.Processor is on reset. Attemped to resd after writing a single nibble
Hi... I've written following code to drive an lcd in 4-bit mode using busy flag.When i simulate my hex on Proteus,i should see "xxxxxxx"but i have " xwxwxw(A'x'=0x78 and A'w'=0x77).I also tested my code for "4444444" but i got " 434343"(A'4'=0x34 and you see higher nibble latches twice alternately and then cursor shifts right and l
I have an ADC result which varies from 0 to 249 in binary. I want to convert this to 00 to 30 which is to be displayed in lcd display. I have already programmed the lcd display in assembly language and is displaying whatever I transfer to it. Just stuck with this conversion. Can anyone please help? I am coding in assembly language. Or just give me
Hi, I am new here. Hope can get help since i'm unable to interface the lcd with my PIC18f4550 by using CCS compiler. I'm not too familiar with the C programming, but i tried to write out a C code. Hope you guys can check and inform me any errors occured. my connection for the lcd to the PIC18f4550: RS----RB4 R/W--Gnd (...)
well my code to get pretend voltage from a 10k pot works great sometimes but others it will show random things even sometimes on the wrong line im using mikroC and a pic 18f4550 what i thing is wrong is FloatToStr because if i remove that part of the code everything is great please help me and thank you sbit lcd_RS at RB4_bit; sbit
mikro c v5.6.1 pic 18f4550 20MHz oscilator(15pf) Hello. I can't get lcd to work.He always shows squares. Frequency is set to 48 MHz. Diplay is ok because he worked with pic 16f887.When I try 18f with led's(using diferent delays) he works ok. here is code: // lcd module connections sbit lcd_RS at latb4_bit; sbit (...)
hmm wy dont u design it by ur self as long as it is a project, u can have volt meter from ADC module, with a voltage divider u can have resistance measurement, and using capacitance to period converter u can have capacitance meter, by measuring the pulse witdth u can make a frequency meter and so on ... its very simple if u just study little and se
There's lots of way you can do it aslo you can do a search on goolge What's the point in having the curcuit wiht the hex file here are some I prefer to design my own,
Yes, it is possible. I have connected a PIC 12F675 (which has an A/D converter) to a PIC 16F628 (that does not have an A/D converter, but it can control a lcd) in another board, via serial communication (USART hardware implemented in the 628 and software implemented in the 675). Some PICs have parallel ports (e.g. 16F877 that can be connected with
The text length depends on the SMS capbility of your service provider. You can send any lengths of texts and you need to merge all of them at the receiver end to run it all together. Interfacing a PC lcd screen to a microcontroller is a bit difficult task as it requires a VGA output. If you choose to use a smaller lcd module, like 16 x2 or even
I had problem using the usart feature of PIC18f4550. I facing problem on sending data using TX pin of PIC18f4550. I tried to send Eg: putc(0b10101010); to send 10101010 to other PIC. It does not show anything. the code for receiving is input = getch(); I using CCS software. Thanks for your professional help.
hi all, im also using ES51918 without a display.and i thought of using Alpha numeric lcd for its display and 18f4550 pic micro controller for the operation.somebody has an idea to handle the serial data ? im in a difficult situation.. Also if someone bought the lcd for ES51918 can u send me the link... ur valuable help will be (...)
hi, i am successfully handled the one DS18S20 using PIC18F and displayed the temperature values in lcd .then problem is how to handle multiple DS18S20 sensor interface to "Single pin of PIC 18f4550"? means how i can search & read the temperature values of each device which are connected to Single pin of PIC
Before this, I had tested the lcd 16x2 and it can be done successfully with the experts' helps from here. Thanks a lot. Now, I'm testing the dc motor with PIC18f4550 with the coding below with ccs c compiler. #include <18f4550.h> #fuses NOLVP, NOWDT, HS, NOPBADEN #use delay(clock=20M, crystal) #define L293D_2 PIN_B3 #define
Hello, I want to read analog values that are being taken in by the PIC 18f4550. I am taking input from a LED which I am using as a Photosensor. Can someone tell me how i should proceed to view the inputted analog data values in MPLAB?
First, you don't seen to have any decoupling capacitors at the power pins of the 18f4550. These are essential (although the chip might work without them, you'll more likely have problems). I take it you are pulling the chip off the board to program it, since you have used the PGC/PGD lines for the lcd databus. Other than that, without
You can use thise project and adjust code for your needs just to shows voltage on lcd, and most important you have example of ADC conversion: code is writen in MikroC. For higher input vol
Even the 18f4550 isn't enough, it only works as a USB peripheral. Check Microchip's web site for suitable devices, there are several PIC18 and PIC24 MCUs that should do the job. Brian.
i am doing project with ultrasonic module hc sr-04,and pic 18f4550,please help me for code.i need to trigger sensot with 10 microsecond pulse,then sensor sends 8 bursts of 40khz...they are reflrcted back from object....if obstacle is detected we get 150microsecond to 25ms pulse at echo pin of sensor else if no obstacle detected we get 38ms pulse,so
hi I have got Pololu minIMU-9V2, in which I'm trying to read gyroscope values. When i connect my sensor its always showing X=-1, and when i disconnect my sensor its showing X=10223 0r X=10877. Since it has got pull up resistor i didn't connect external pull up resistor. my code is #Include <18f4550.h> //#use delay(xtal=20Mhz) //#fuses NOW
