Microchip has good product selection tools like this one: http://www.microchip.com/maps/microcontroller.aspx (note the plus signs on the right side of each section) > I don't know what all the features PICs have, but for my first > project I would like to have it connected to a serial port on > one of my Soekris' where it can grab info (i.e. the current > time, or NTP/GPS info) and output that on a little LED display. Depending on the type of LED display you have in mind, you want to have PWM capabilities (multiplexing) and high current source/sink, as well as an (E)U(S)ART for the serial communication. A four digit LED display can be easily controlled by a PIC16F1503 (price about 0.8 USD, 14 pins) and the required documents are available on the Microchip site: http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en553475 You can do the UART part in software for low data rates or simply take the PIC16F1508/9 which already includes an EUSART (price about 1.3 USD, 20 pins) One programmer for many PIC chips (8 bit to 32 bit) is the PICkit2 which can be bought for less than 30 USD (via usb, works fine on Linux and MacOS as well) HTH, Herbert > _______________________________________________ > time-nuts mailing list -- time-nuts@febo.com > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
