    [SOLVED] [Verilog] Data is not transferred from one register to another

    Hi, I have instantiated a stopwatch module into this multiplexer module. The stopwatch is working as it is supposed to and is producing the expected output. This is also picked up by the instantiated registers, but if I want to use this data further down the module, it does not work. For...

    Testbench giving unknown (x) on output

    Hi, so i want to make a simple code to make an LED blink. here is the code I have module led_glow( input clock, output led ); reg [5:0]count; always @ (posedge clock) begin count <= count+1; end wire [3:0]PWM_in; assign PWM_in = count[5]?count[4:1] : ~count[4:1]; reg...

    Making sense of this image to array code

    I want to convert an image to a character array, I was able to find this code: void main() { fstream image; image.open("C:\\pic.bmp", std::ios_base::binary); //open pic in binary mode image.seekg (0, ios::end); //count from end of file to beginning int n = image.tellg(); //store current...

    Go to start after interrupt?

    I understand that when an interrupt occurs the micro controller returns to where it left from.. but my interrupt consists of a stop switch, i.e. after the iterrupt I want it to stop everything.. my code consists of running a motor in a while(1) loop.. after the hardware interrupt is pressed it...

    Ideas for connecting to analog input of PIC

    Hello, I have written the code for it and now I want to actually make it work. Its used to test or check resistance, and i am using a pic with analog input.. I was just wondering how to make that possible? I know that I can drive a constant, known current through the resistor and then how do...

    verilog for simple timer?

    Can anyone here give me the verilog code for a simple timer which generates a continous stream of interrupt pulses at intervals determined by a parameter abd each pulse should last 4 clock cycles. I got most of it done but it lasting for 4 clock cycles i dont know how to do. Thanks
