Hi, How to use LM335Z in general and with 16f877a/16f84a ?controllers? Any beginners guide on this topic? Thanks in advance AG
I have made a K149A programmer, it programmes the 16f84a very well but donot programme the 16f877a .I have checked the hardware many times through out but there remains some problem it donot even detect the 16f877a . I have used a 16F628A instead of 16F628. Can some body help me about this problem. Is there an thing missing in (...)
i just want to know the difference between 16f877a & 16F877? and 16f84a & 16F84?
hello When I needed a 16f877a programmer , I searched the web.. Yes I found many , but most of them are complex ( or at least not simple ) But I have found this programmer from my friend , it's very simple to use this

Hi there, I just upgrade my mcu's from 16F628 to 16f877a and i have lots of problems now.I even don't have an idea how to use it.Let me describe my is so simple but i cant do it.I have a 16F877, max232, 2 leds, 4 caps (1uf), 2 ceramic caps (22 pf), an xtall (4mhz), 3 resistor (10Kohm, 2 * 220 ohm).I want to measure 0-5V voltages via p
Did you look at the erratas ? I had big problems using 16f877a above 4MHz clock and returned and exchanged them to non A types. We wanted o save some money using the A types as they are a little cheaper ...

From where can i download a good free pic simulator ( 16f84a & 16f877a in particular) other simulator found in MPlab , maybe a simulator where i can add leds and push buttoms. thx
Salam, CCS is not free :-( bctang Please don't start to cry.... :cry: :cry: You can use HI-TECH LITE for free It support 12F629, 12F675,16C84, 16F84, 16f84a, 16F627, 16F877, 16f877a As you see it can program 12F629 and 12F675 and both of them 8 pins :-) h
Salam kseng2002, Do you use Hitech Lite version ? This version is not suppot PIC16C73. HI-TECH PICC Lite compiler supports 16F877, 16f877a, 12F675, 12F629, 16F627, 16F627A, 16F684, 16C84, 16F84 and 16f84a devices AnyWay, Give look to Bye
Hai I have a new MPLAB ICD2. From microchip. I have tested it with demo board (Microchip) with PIC18 chip. Everything OK. I have connected it with my own target board(16f877a) which is working alright without ICD, MCLR clean- only 10k resistor. Self test is passing. 16f877a -ICD loads new operating system, but fail
Hi I have a dumb question, i think I am missing something very basic here. I cant seem to get TMR0 to increment in MPLAB, and i don't think it is working in the PIC either. First I setup the Option_Reg, and set T0CS, in order to turn the timer off. When I want the timer to count I clear T0CS so the timer will increment off the internal clock. T
Hi, Does anyone have a routine for TC72 spi sensor with 16f877a ? I would prefer pascal. Or can anione tell me how to controll it step by step? Than You András.
This has an internal oscillator, so you shouldn't need anything except to pull MCLR high. I'd recommend studying the datasheet: The 16F877 has no internal oscillator, so an RC, crystal or resonator and some caps are needed (see datasheet: 12.2 Oscillator Con
Hi ! Do you have any idea of how to messiure DC voltage (20volts-5volt) and current (~15 volt 0-25 amper) with pic 16f877a, even with external circuit(s). Thanx András
I'm looking for a pic 16f877a stepper driver schematic and any code i can find. The plan is to have a pic run a 3 axis cnc router table with input from the serial port of a desktop computer. I have already gone through the piclist. Using max232a and a pic16f877a and a series of transistors to run the stepper motors. I already have a good idea

Dear all, i have a technical problem with my desing of 16f84a . i design one kind of remote control with pic 16f 84a and make code protection enabled. because of the virus i lost my harddisk . i had to make hard format to my harddisk. so i lost my source code too. so i needed to know that is there any way to read my pic again by making code
Hello boys, Does anyone used the max6953 to drive 4 5x7 led matrix displays? I would be very grateful for some sample code to address the max6953 from a pic(16f84a). I have difficulties understanding the protocol from the datasheets. Thanks Nikos Geronikolos
Hi all, I?ve a 16x2 LCD module, not sure at all if it?s HD44780 compatible. I need to drive this one with 16f84a just to verify if it?s working properly. I tried to make it work with no good result. Can anybody give me the working code for the same? Thanks
I am trying to interface the pic 16f877a with ds1302. i use ccs and its driver for ds1302, but a have no sucess. The ds1302 have a TCXO (ds32Khz) to generate the 13.768Khz clock. If someone have a simple code to read a date/time register in ds1302, please post it. tanks in advance...
Assalamo Alaykom.. Please if anyone knows the addresses that are available as an EEPROM space in the PIC 16f84a , please tell me what are them .. i.e. i need to know the starting EEPROM address and the end Address where i can read and write unvolatile data in them .. i hope you can understand me .. and can answer me also ..[/s
First, maybe your programmer can program only 16F84 not 16f84a. For example, programming methods are diffrent between 16f877 and 16f877a. Second, I used to use JDM programmer with ICProg. For ICProg, I had to run a reg file for winXP. If you are using WinXP or NT system, you should do that. You can find this reg file from ICProg web site.
Hi, Can anyone give me a good link for doing I?C with PIC 16f877a. Circuit diagrams and codes etc. Thanks Rob
How to make 31 days delay, using 16f84a? Please Help me.
Hi, I wrote some code for the 16f877a and simulated the program with pic simulator ide which seemed to yield successful results. However when I programmed the chip with a datman 48uxp universal programmer and tested it I got no response at all. the chip was completely dead! I tried again with a spare chip, same model but got the same results. I
Hi everybody! I'd like to know the differences between 16f84a and 16f84. And what is Ghost location? Pls do me a favour. Thanks in advance

Hy... I'm implementing a temperature meter based in the ds1820. It works great, but now, i 'm trying to do the high resolution mode. i need to do a math equation that is: temp = temp_read - 0.25 + (count_per_C - count_remain)/count_per_C these variables are int. The 'temp' must be float because the division, right? Can i do a diviso
All the information you need is in the 16f877a datasheet The addresses of the general purpose ram is in section 2. The instruction set including the instructions for setting and clearing bit is in section 15. To use this microcontroller you have to read the datasheet.
