Brian, you shuldn't, but I've just did. On PIC16F628 (not A) that location is scrambled by Pickit2 during bad programming. Once is erased ( reading the memory content with other software such IcProg) you can see the content FFFF. Icprog is able to rewrite that location, once is written Pickit...
Hi there,
This is the right solution for a closed thread named "Can't Reprogram PIC16F628A with Pickit2".
The PICKIT2 (or PICKIT3) is reading the ID of the PIC16F628 which is located at the address 2006h. The correct value you should see at address 2006h is 07C0h. If by mistake that value was...
Hi all,
I'm searching for the operating manual of an old Q-meter (30KHz-30MHz), Tesla TM392, perhaps it has 16 pages, published in 1951.
I need only the oscillator section (UBL21 tube).
thank you!
The first step in a PCB project is creating the library package, by modifying other existent library. You should start learn this because someday you will find one package which has not been edited yet on Eagle by anybody else.

This question is demoralizing any guy which 25 years was playing with electronics...including me.
You like or not, the "Electricity and magnetism" chapter from physics must be read and understood.
During this read, start practical activities: soldering, understand the electronic components and...
Dear Colleague,
International Journal of Practical Electronics wishes you love and health for 2014!

Joyfully win EURO200 for the best accepted manuscript (research or technical article) submitted to IJPE till 30 January 2014. The paper should discuss...
Re: HOW TO MAKE PC VOLTAGES AND MICROCONTROLLER VOLTAGES SAM
Please ask a good question and you've got a good answer. How the heck you want the reader knows what are exactly your voltage levels? Every problem may have a particular solution. Ask yours again.

This is a too complicated chopper for a logic analyzer, however seems OK, except maybe the output DC level converter. The output "fixed current source" is a variable current source driven by the logic signals.
Re: PIC16f877a
Both the CCP and PWM must be understood as hardware standalone modules which properly programmed can perform tasks in the same time your instructions in the firmware are executed.
One example is generating a 50% dutycycle of a KHz signal with the PWM while a 1mS real time clock...
In a few words:
Any track is creating an attenuation and it's adding a delay. A track for a high speed design could be microstrip or stripline (simmetrical or not), coupled or not.
A free program which is computing attenuation and phase shift for a given track is here...

Read datasheet. There is one usefull output 35V. FBO is a voltage used for a microcontroller AD measurement and REG is the feedback that microcontroller is providing for modifying the output voltage. SBY is a standby input.
It might be a 70W SMPS. About the trace routes you...
