Hi, I have a project where I have a PI16F88 to communicate with a PC via RS232, and control a relay, and read an ADC. When I have the PIC kit 3 interface connected to my board and MPLAB is communicating with the PIC my code works fine. As soon as I disconnect the PIC kit 3 from my board, and reset the power the code stops running. I have a 1k resistor pulling MCLR to 5V, and a 0.1uF capacito...

Hi, Folks! I read the ED article in file "1 pin Keypad.PDF" posted by dave_mucha, and compared it to the "4x4 Keyboard with 1 Input" tip in Microchip's Tips & Tricks guide. The latter has far fewer components external to the PIC. Has anyone met with good success using the method in that tip? The device I am designing will use a 4 x 3 keypad, with a layout similar to a Touch Tone telephone....

Since I know that there are a few ham radio operators here I thought that I would ask if anyone has used a pic to communicate with an Icom radio using the CI-V port (an open collector TTL level bi-directional serial data port). I am thinking of trying to build a screwdriver antenna controller and would get band and frequency data among other things thru the CI-V port. There are controllers availab...

What's the difference between a 16F676 i/p and a 16F676 e/p? Mouser and Digikey have both types and they appear to be the same, at least on the data sheets. Mouser has the one style (e/p) in stock but not the other. Digikey doesn't carry the other parts I need so it isn't just a matter of where I order. Thanks ------------------------------------

Hi I have developed some code to control RGB LEDs from a PIC16F873A chip. The code was working, but now the oscillator is not running. I've checked the connections between the crystal, processor 4MHz crystal, and 22pF caps, and everything is in tact. I'm using the CCS PCM C compiler, I have set the #fuses to: #fuses XT,NOWDT,NOPUT,NODEBUG,NOPROTECT,NOBROWNOUT,NOLVP,NOCPD Can someone my b...

Hi gang, I just got a mini lathe, and am thinking about making a nice little tachometer for it. I know there's a whole pile of new stuff at Solarbotics, but I haven't researched anything yet. If anybody has done something along these lines, what did you use for a sensor? Cheers Gary ------------------------------------

Page 2 of the following document shows two pulses that I need a PIC to analyze: http://www.phoenix.tc-ieee.org/0001_Bibliography/2007-05-24%20EMB%20Presentation/2-Carl-Sensors_ 20070520_Phoenix%20Sensor2.ppt Basically, there are two pulses from two sensors. The systolic blood pressure we're measuring is a function of the time difference between the peaks of the two pulses. The diastolic blood
