    How to check a L298/L297 circuit ?

    l298 l297 hi, i'm designing the same schematic, I read in the datasheet that the CONTROL pin of the L297 should be connected to VCC if we need to activate A,B,C,D outputs and GND for /INH1 and /INH2, does this mean that : if we have an unipolar stepper motor----> connect CONTROL to GND...

    import a netlist from ISIS into Eagle ?

    understanding an isis netlist Hi everyone, I have made a circuit using ISIS 7.1 and now I would like to design the Circuit PCB with Eagle Cadsoft (I have the 4.01 version), I found in ISIS that it is possible to compile the netlist in different formats (Multiwire,spice,tango,SDF,...), so...

    PORTb interruption (CCS compiler)

    portb ccs hi Saeed_pk, My PIC is a 16F876, if you don't mind, what's the difference between them ? now only one interruption comes from RB6 and is generated by a push-button, (just to test the code) but then I'll have to manage at least 3 other interruptions inputs in the other pins. I...

    Difference between PIC 18F4525 and 18F452

    18f4525 Hi everybody, I compiled a very simple C code ( written for the PIC 18F452) and I simulated it with MPLAB SIM in a PIC18F4525 , strangely, i found complete diffenerent outputs: 0x40 (0b01000000) insted of 0x5A (0b01011010) . 0x20 (0b00100000) insted of 0x3A (0b00111010) . did the...
