    Telit GM862 problem [URGENT]

    There is neither source code nor schematic. The thing is simple: I connect only power supply, then I power on the modem and TxD pin is high only for a second, instead of being constantly high. Can somebody help out? What can be a solution?

    Serial communication with PIC16F84

    I'm using 16f84, and I need to program it, so when it receives some data, for example 8bits (with UART standard) it checks if received data matches to other data previously stored in eeprom, and if it is a match case it will go to one label, and if it isn't that it will go to other label. It...

    [SOLVED] Main difference between ATMEL uc and PIC uc.

    Well, I personally use PIC, but you should know that with both PIC and ATMEL you can do a lot of things. Also be aware that when you're using PIC it divides frequency with 4! For example if you put 4Mhz crystal then ATMEL will work on 4Mhz and PIC on 1Mhz. I can assure you that if you choose PIC...
