Hi there, Dennis.Haven't heard from you for a while!Most PIClisters spend their time at the PIClist mailing list maintained at MIT. You can head over to for instructions on how to join that list.An awful lot of people also spend time at . This is a great question and answer site but they don't allow idle chit-chat. Thus:

Hi,I am working on a project using a PIC 16F1827, using it's internal oscillator running at 8MHz. Ican download firmware into the micro and verify that the code has successfully been programmed.However the code does not appear to be running. I have verified this by writing code to toggle apin and have viewed this pin on an oscilloscope. I have pasted my code below. Could someoneenlighten m...

I am attempting to establish serial communications with UART1 or 2=20on a PIC24HJ64GP502. MPLAB IDE v8.76 and c30 v3.30.=20I am using a MAX232 and serial-USB converter to a Win-7=20PC running hyperterm (9600-N-8-1). If I pull the PIC and jumper=20pins 21 and 22 together I get a proper echo on the PC, so theconnectivity is good too/from the PIC.Current program does nothing but try t...

This group has been way too quite for too long. I thought I'd liven things up a bit by asking aquestion. I would like to use the on chip A/D converter in a Pic 16F887 and I have someMicrochip MCP1541 4.096 voltage reference devices. I need to be able to measure voltages up toaround 18 volts. If I use a voltage divider that divides the input voltage by 5, I could measureup to 20.46 volts. So fa...

I have been trying to write to a 24LC1025 EEPROM which uses an I2C interface without success.The software I2C routines that I am using are the same ones that I have successfully used with aDallas 1307 clock chip and were downloaded from the Dallas website back a few years ago. Usingmy Pickit2 programmer I wrote some data into the 24LC1025 chip and using these routines I amable to read the data...

Hi allI have a question regarding the speed of microcontrollers. As I knowthat RISC mcus such as PIC need only 1 clock for each instruction whileCISC need several clock (8051 need 12T). That's why PIC is usuallyfaster than 8051 (for the same clock frequency).I noticed that there're many 8051 core microcontrollers (STC 8051 , siliconlab

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 iscommunicating with the PIC my code works fine. As soon as I disconnect the PIC kit 3 from myboard, 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 fewercomponents 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 Tonetelephone....
