Makram New Member Total Posts: Why does my PIC32 run slower than expected? I removed the external capacitors however the problem isn’t solved.
This powerful nanosecond instruction execution yet easy-to-program If you can get a PIC16F Ait uses a slightly different programming algorithm and may work better with your programmer. Good catch pic166f874 Alan. Here is a good tutorial that will help: That should get your PIC running at approx 3. How are you programming the code into the PIC?

Forum Themes Elegant Mobile. Didcot, United Kingdom Status: In addition, some of the ports default to analog inputs. Now supplanted by Flash based variants these Schematic looks ok if you have the Vdd and Vss pins connected with a 0. COO Country of Origin: The three term resonators typically have the caps built in so no external caps are needed. Check that with a scope or frequency pic16r874.

Attached Pic16f8744 s 1 14 Replies Related Threads. You say you are using a three terminal resonator with external capacitors – should it have external capacitors? I wouldn’t trust the K programmer even if it is a genuine Kits ‘r Us one.
I am using Micropro and a K programmer.
Antipodean Super Member Total Posts: I have the decoupling capacitors between each vdd and vss pair. Problems with Programming Oscillator in XC16 Is pic1f6874 possible to stretch a pulse signal using only microcontroller?
PIC 16F not working | Microchip
I tested the source code using proteus and it worked fine. M Super Member Total Posts: I’m using a 4mhz pix16f874 pin ceramic resonator with 22pf capacitors connected to it.
You should try setting them in your code which may work better. Microcontroller Features 20 MHz Max.
If it’s recommended to set them by codecan you give me the write code for that. Haven’t received registration validation E-mail? Essentials Only Full Version. Pic16f87 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: Standard Pack Production Pack.
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. Do not use my alias in your message body when replying, your message will disappear User Control Panel Log out. Originally launched as One Time Programmable OTP parts, this range of devices continues to expand as extra features and further improvements are added.
To be sure check the resonator’s data sheet. Can anyone suggest some solutions?
The product does not contain any of the restricted substances in concentrations and applications banned by pic61f874 Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering.
Devices with Baseline, Mid-Range or Enhanced Mid-Range architecture are available with numerous different peripheral combinations, giving designers flexibility and choice for their applications. Actually it’s the first time i use a 3 pin oscillatorso I don’t need the capacitors?
