The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering. To be sure check the resonator’s data sheet. Actually it’s the first time i use a 3 pin oscillatorso I lic16f874 need the capacitors?
I am using Micropro and a K programmer. Here is a good tutorial that will help: Antipodean Super Member Total Posts: I removed the external capacitors however the problem isn’t solved.
The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering The restricted substances and maximum allowed concentrations in the homogenous material are, by weight: I tested the source code pic16r874 proteus and it worked fine.
This does not directly effect your code since you are only using portB pic16ff874 is only digital pic168f74 if you use portA for digital then you will need to disable the analog features.
How are you programming the code into the PIC? Why does my PIC32 run slower than expected? You say you are using a three terminal lic16f874 with external capacitors – should it have external capacitors? I’m using a 4mhz 3 pin ceramic resonator with 22pf capacitors connected to it.

Now supplanted by Flash based variants these That should get your PIC running at approx 3. Schematic looks ok if you have the Vdd and Vss pins connected with pic1f6874 0. I have the decoupling capacitors between each vdd and vss pair. Attached Image s 1 14 Replies Related Threads.

You should try setting them in your code which may work better. Problems with Programming Oscillator in XC16 Is it possible to stretch a pulse signal using only microcontroller?
If you have already tried 2 PIC16F chips then it is unlikely to be the PIC – they are remarkably robust and unless both are pulls from the same previous catastrophically failed project, they would be unlikely to be blown the same way and still program and verify.
Check that with a scope or frequency meter. If you can get a PIC16F Ait uses a slightly different programming algorithm and may work better with your programmer.

Haven’t received registration validation E-mail? Didcot, United Kingdom Status: The three term resonators typically have the caps built in so no external caps are needed.
RS Components Statement of conformity. Forum Themes Elegant Mobile. Can anyone suggest some solutions? In addition, some of the ports default to analog inputs. I’m starting to wonder if the MCU is damaged although I’m using 4.
Good catch from Alan. Essentials Only Full Version. I wouldn’t trust the K programmer even if it is a genuine Kits ‘r Us one. Standard Pack Production Pack. M Super Member Total Posts: This powerful nanosecond instruction execution yet easy-to-program COO Country of Origin:
