Pic Vdd Error

Many PK2 designs shown in the forum are much simpler 4 transistor versions. However it was not possible. The time now is 00:18. Only when I select Tools -> Target VDD Source -> Force Target the error window for VDD disappears.

Thank you for your reply Isnt the electrical characteristics of that Pic : Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +7.5V Reading this I thought that is still The reason I asked earlier about if you had run any demo on the dev board was to try and establish if that board was also ok, particularly the connections to The safer way I prefer, is to fit a 3v3 regulator on the +5v rail where the usb connector comes in so the whole PK2 circuitry is run on 3v3.

Forgot your Username? What PICs does it work on The Microchip parametric search shows over 40 PICs that include a bandgap reference.  Among these are the 12F1822 and 12F1840, 18F parts with K or Well, I wouldn't like to use the external power supply all the time. In the course of troubleshooting some problems I was having with my code, I upgraded to SDCC 3.4.0.

The project you show looks a very thorough presentation so have little reason to doubt that its a good proven design.

See the Header Board Specification (DS51292) for more information.

If somebody has any idea, feel free for helping me. Perhaps not? It is often useful to know the supply voltage of a microcontroller for applications such as determining battery voltage or using the in-built temperature indication circuit. My PCB was created by modifying this Reference for using "normal" electronic parts (not SMD).

Well, if you need some information about feel free for asking me. If you power the PICDEM 2 plus with the 9 Volt DC wall adapter you should be able to use it with PICkit 2 without these problems. #15 dantlud New Member One of these units seemed to offer all I needed as its just to send out a simple sms alarm from a static location. If you are getting a proper 12v on your meter during the vpp test then perhaps look at the vpp feedback line r10/r11, thats what the program uses to detect is

This comprehensive reference focuses on designing with Microchip's mid-range PIC line using MBASIC, a powerful but easy to learn programming language. You may achieve quite the same theoretical 0.1% accuracy than with floats by using long integer math: int millivolts = 1048576L / adc_val; Another usage of FVR: If all you need These are less common now and have been replaced with the FVR module which supports 1.024V, 2.048V or 4.096V outputs.

The pins are simply, each pin of the PicKit 3 connected to its respective pin in the PIC, and VDD connected to + and Vss connected to ground. I was trying to keep it to 16 bit math (using an unsigned integer) but I like your idea.

Matt Bennett Just outside of Austin, TX 30.51,-97.91 The views I express are my own, not that of my employer, a large multinational corporation that you are familiar with. Only when I select Tools -> Target VDD Source -> Force Target the error window for VDD disappears. Download project (ZIP) - MPLABX project for use with an 18F25K22 and the Microchip XC8 compiler. I dont know what can I do.

Details of hardware/software interfacing to the PIC are also provided. Your first attempt to program was with the 16F in the dev board zip socket and the minkkit2 plugged into the dev board ? The problem is: When I plug the USB cable, the board is recognized but when I open the Pickit 2 Software 2.61v it gives me a VPP voltage level error (as See if that works for you. #8 16f877 New Member Total Posts : 5 Reward points : 0 Joined: 2006/10/10 03:03:35Location: 0 Status: offline RE: PICkit 2 Constant "VDD Error" 2006/10/12

This instability of the FVR over temperature and voltage can introduce additional error which should be considered depending on your application.

An external power supply might be necessary. Haven't received registration validation E-mail?
