Colleagues, Until now I've only worked with the 12, 16 and 17-series of PICs. There doesn't seem to be a clear and simple explanation on Microchip's website of the dsPIC series, in terms of what they are good for and when you would use them in preference to the other families. I wonder what specific strengths and weaknesses they have. Could anyone elucidate? Thanks, SteveT ----...

I am building a optical tachometer for a gas turbine. I would like to try my hand at PIC programing. I have programed AVRs in the past and feel its time to try microchip's line (mainly because I got some samples from them ;-) I already designed my board layout and intend to use a

Hello, I've got a Pharos GPS-500 USB dongle on hand and I was wondering if it would be possible to hook this up to a PIC of some kind. When I plug it into my PC it is detected as a serial port by windows and the data just streams over as ASCII test. Anyone have a direction they can point me in? I've been looking at Microchip's website, but most of the stuff is on peripheral side devices....

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....

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