    Problem with using ADSP-219x SPI

    I have to communicate two analog Devices DSP, everything works fine when I send messages only from master to slave. But when I set the bit EMISO (bit 5 of SPICTL) for sends data from slave to master the system stop work and I receive only wrong data in both sides. Please if you have some advice...

    Mesuare current without a shunt resistor

    shunt resistor pic Hi friends I'm using a PIC16F873 to generate a PWM that drive a NMOS transistor that drive a motor DC. But now i need read the current that flow throw the motor and i don't want to use a shunt resistor. Coul you tell another cheap sugestion? Thanks guys Jundiaí

    How to program a serial interface for PIC with PC ?

    How can i do it? I have a PIC comunicating with the PC by the Hyper Terminal, but now i need create a interface to the users and i don't know how. I know how to program a few in delphi, c++ and labview, but i have never programed a serial interface. Which language i must utilize? How can i do...
