Hi to everyone!! Although it is not really a pic issue I am going to describe what happened to me. If anyone knows why I would be really grateful to hear about. During one of my projects I used 2 x 7805 for dual +-5v supply. Each one of them had was supplied by a 9V battery(that means 2 seperated batteries). I connected the output of the second 7805 to the ground of the first o...

I've adapted a C version of a PSK31 data encoder to Microchip assembly language for the PIC 16F87x micro and made a few improvements along the way. Hams (and others) may find this device or simply how it works, to be useful. Details and the the source code are available here: http://www.ringolake.com/pic_proj/PSK31/pic_psk31.html Mike Berg N0QBH

Guys need your help I have a cheap commercial PIC programmer based on the JMD design. It works fine, but I have subsequently found that it will not program 18F2550 PICs via ICSP, but will work fine when the PIC is placed in the sockets on the programmer. A friend therefore suggested that I use a bootloader which will make for rapid loading and testing of the development code I'm wor...

Hi, For a while now I've been wondering what does the A in 16F877A means? I mean what is the difference between a 16F877 and a 16F877A? My other question is what is a bootloader?

Hi, I was wondering if there is a preference ina aprticualr PIC model that is use more often for robotic. I know the 16f877a is a good general purpose but is there anything better. I mean, something that is 1) well supported, 2) has plenty of program memory 3) has the features that robot builders like like PWM ADC channels and what not. Again, it has to be something common. Maybe theres

Hello All, Can someone tell me which PIC has 2 ADC module? Can they run simultaneously although with a few ms of delay due to program sequencing? Thank you. Relax. Yahoo! Mail virus scanning helps
TMR2 output and the SPI block

I'm running a 18F6680 at 40MHz which means that the SPI clock's slowest setting would be 625KHz, which requires a pretty fast set of opto isolators in my case. I'd like to run it a bit slower. TMR2's output can be used as the SPI clock, but I'm curious as to the details. Does the PR2 register control this register output? The document isn't that clear - IOW, if I have a 40MHz/4
One pin for both an input (switch) and output (LED) ??

Hi all, I am looking for a way to use one pin for both an input and an output. An LED is the output. and a switch would be the input. I can see a few ways to have both on one pin, but not sure if there is a preferred way. It seems the simplest way is to have a resistor, and LED and a switch all in series. then pull the LED-switch line down to power the LED, then monitor the voltage to t

I'm looking at the datasheet on MBC25081TB steppermotor driver by Anihiem Automation. It shows two pinout diagrams one for sinking inputs and the other for sourcing inputs which are an the same pins. Will someone tell me what is meant by sinking and sourcing inputs? thanks bill
