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 ------------------------------------

I'm using MPLAB 8.43 (full installation, including PICC 9.70) in WINE (wine-1.0.1-174-gc4039bd) in antiX Linux M8.2. I'm having difficulty with code that worked fine in MPLAB v8.10 and HI-TECH C PRO v9.60PL3 (free version) in Windows XP. For the complete code, go to http://www.jasonhsu.com/swrwatt-c.txt When I click on "Build", the build fails, and I get the following error messages: ...

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

Hi, I've just started a project using a PIC12F675. Just to get started I'm trying to drive all of the port pins high, but I'm having no success. I'm aware that the ports have multiple functions and need to be set up. I don't seem to have nay control over any of the pins. I'm using HI Tec PICC lite embedded into MPLAB 8.1. My code is: /* PIC 12F flash.c */ #include "pic12f6x.h" vo...


Variable Symbols in File Register

Hi Group, Is there any way get MPLAB asssembler to show the cblock symbol names from a list of variables created by cblock? With a large cblock of 30-40 variable symbol names it gets to be a real pain to find the right address when looking in the file register while debugging. Also, with byte size variables, MPLAB does not include or allow me to drag and drop any of the cblock variables ...

Dear All, ? Need Help! ? I?want to know whether the chips designated "LF" (low voltages devices, Example :PIC18LF2580 ) can be used as normal "F" designated chips( Example: PIC18F2580). I know the vice-versa is not true.?Whether all the ports,I2C,SPI,SERIAL n so on?etc ?of "LF" chips? function as standard "F" chip at +5V. I mean are there any restrictions or limitations. Can i replace PIC18F...

I have recently come across a circuit diagram: http://f1.grp.yahoofs.com/v1/ULBpSg7H1FfAWrKBp02HDaRkyq4iFpOjfpH78Kql4Dxq0CgSrNLnPzPzZIhq_C7J8z1 8rM7VyWwp3bC8n2uBiJDZsrfy/PWM.jpg Now the purpose of this circuit, is to convert a 5V PWM Signal to a 0-10V Output. The details of the PWM are unknown. So it could be a normal type of PWM, with the mark to space ratio changing, but seen as it is a

I'm part of the Data Acquisition subgroup of Project Phoenix, a group working on an open source blood pressure monitor. I'm trying to figure out what surface-mount microcontrollers we could use. I need to figure out what our options are before I decide what programmer to get.
