Trying to program the pic16f887 using MPLAB v8.90 andPICKit3. Returns "Target Device ID(00002080) does not match Expected Device ID(000009a0). Using target P/S. Microchip has been unable to aid me. Have checked the wiring until they are nearly worn out from looking. I'm using a breadboard with only the wire necessary to program the (...)
please upload your program... Which program are you referring to, the OP doesn't have a code, he is asking for the code...
hi guys, i and just trying to get the rs232 data out to the LCD by using the pic16f887. i made a test program for this and i have searched around and came up with this code: include "D:\Projects\asdfasdsa.h" //#include #define LCD_ENABLE_PIN PIN_B5 //// #define LCD_RS_PIN PIN_B4
Hello members, I tried to write a switch to led pgm using embedded C the o/p..but couldnt implement the same concept in is my program..couldnt guess any logical error so far..there is no syntax error also while I tried building it.. #include list p=16f887 ORG 0x00 GOTO MAIN ORG 0x12 MAIN: banksel ANSEL ba
That code is difficult to read, here is how to make it understandable: 1. use code tags around the code, the '#' in the bar above the message window. It tells Edaboard not to reformat it so we see it as you wrote it. 2. instead of using addresses, please use names. for example, at the top of the program use: cblock 0x20 delay_1 delay_2 delay
Hi guys, I am quite new to chip programming, and I have been set a task to try and program a pic16f887 to display, with some LED's, hexadecimal characters while using the hyperterminal application within windows, well at least that is the first part. I understand the concept behind the whole process however I am quite new to (...)
hi! i got this project and im currently woking on testing my pic16f877. im interfacing this pic to a computer using usbmod3 via max3100.. i have an old program for 16f877 from my previous project. this program is for interfacing the pic to a computer via rs232. does anyone have a sample program (...)

Hai Alsindi, please open the .asm file, enable the line ; __CONFIG h'3F31' by removing the semi-colon save the file in a location like c:\ call mplab select the device properly and then, project build it will save the hex file at c:\ with the same file name as asm use it to program the chip it works Sarma
Is there any program that supports programming the pic16f887 under Linux, using a JDM programmer? I tried PikLab, and while it can compile programs for the 16F887, it doesn't support programming the device. Any help would be appreciated. Thanks.
Hi lacoste, I present here a simple voltmeter with 16F887 (0-5v scale). But mind it, this is very basic with no input overvoltage protection. A voltage greater than 5v applied to the input will destroy the 16F887. Source code (written in mikroBasic): program softwarefor887Voltmeter dim LCD_RS as sbit at RB4_bit LCD_EN as sbit a
uhm.. HI! I have here a sample program but I can't seem to figure out how to simulate this on my oshon software's pic simulator. Nothing seems to happen whenever I load this program and try out different combinations of the input in Port A. Any help would be very much is really needed.. Thank you very much. Sincere
My question is : I am using PIC KIT3 to program the chip pic16f887 when i connect the programmer to the target board ....the message is being displayed "Target Device id (00000000) does not match expected device Id ( 00002080)". Is my pic being damaged?
there's some difference. however, it is best if you already know what you want, highlight it to us, then it's easier to narrow the difference. example scenario: i need to sample analogue voltages from 10 different sensors simultaneously. then from there we can say that your PIC16F877A only have 8 ADC channels, so it's insufficient... but if you u
I wrote two programs just to check how PIC timer works with internal and external clock. But when I check both my program on ISIS Proteus 7 they are working abnormal. Please also check my code that, are they written correctly. Note that are not for specific purpose I just want to check timers. for internal clock (...)
you need to prevent the mcu from going into sleep state, add an infinite loop at the main procedure, something like this. void main() { procedure1(); do{ } While(TRUE); } When the MCU goes into sleep, the program execution stops, so to keep the mcu busy you need to give it work.
Here's a PIC project using MikroC which scrolls text across LCD remotely controlled via serial port to PC: A PIC Serial LCD project You should be able to download the project code and use it as a template for your program.
Observations: You can save yourself a lot of grief by using 'banksel' instead of switching banks by changing bits in the STATUS register. See the help file for instructions. You will have trouble if you try to use interrupts. Nothing is wrong with your code but if an interrupt occurred it would almost certainly crash the program. I'm assuming yo
The code is useful. I got only 90% of it. you wrote ANSEL=0b00000000; ANSELH=0b00000000; I don't get it. These two are not physical general purpose or specia function registers. than what are this? please answer. P.S. you initialized LCD in 4-bit mode, I need it in 8-bit mode. What changes are to be made? A

Hi guys, I have problem with writing to the internal EEPROM on pic16f887. As you can see in the code below, I am using LEDs on PORTB so I can watch where the code stucks. So, the problem is: EECON1,WR bit doesn't set at all (and the PORTB,2 indicator LED doesn't go "1"). And I really can't figure out what causes this problem. Please help

Check the RAM map of the LCD module, it's quite common for the top line memory to be longer than the physical display line and it may be wrapping around to the third line. Same with the second and last lines. As @grieblm states, the shift commands just slide the viewable part of the RAM along the memory map. It isn't easy to fix, the simplest way
Your PIC available ram is less that the amount you are trying to use, you have to reduce the storage for all variables in your program Alex
Actually two interrupt vectors in PIC18 and possibly more in the PIC24, 30 and 33 series. I first started programming PIC devices when there was only one, the PIC1650 and I can't answer the original question either! Almost every PIC type has a different number of GPRs and I cant think of a single PIC that only has 6. Brian.
Good information for beginner. I'm start learn PIC using PIC16F84A. Then by the time, I'm using PIC16F877A >> pic16f887 >> PIC18F4550 >> dsPIC30F4013. All this using PICKit2 programmer. Then recently, I get PIC32 starter kit. This is need PICKit3 programmer.

Hi, As part of a uni project I need to program a pic to vary the PWM period and duty cycle in conjunction with 2 potentiometers. I have set up both ADC channels and have checked they're both functioning properly. The PWM is set up and running. One of the pots works fine with the ADC to provide a new value for CCPR1L and thus change the duty
