  1. Hello. I'm new to Verilog and I was assigned to code a servo controller in Verilog. The system clock runs at 50MHz. The period of the servo is 20ms, the minimum pulse width is 0.6ms (at 0 degrees), at 1.5ms for 90 degrees, and 2.4ms for 180 degrees. When the user presses one of the buttons on the FPGA and the button corresponds to increment, the servo has to move 5 degrees clockwise. If the user presses the button corresponding to decrement, the servo has to move 5 degrees counterclockwise. Please help me. I looked online for resources but I don't seem to understand them. Thank you so much in advance!
  2. Hello all, Can anyone help me in Basys 3 project? I am trying to interface Analog Sensor to Basys3 XADC pin. I am trying to use the sample code given wiki basys3. Priority: 1) Where do we change in given code for any specific XADC pin. I could not find any 'pin' definition in behavior code. Why there are some IP code files there? It is not UART though. 2) How to generate PWM for Servo motor?
  3. Good day, I am looking into implementing a design, using MPLAB X IDE, capable of driving the Servo Motors on a Cerebot 32MX4 PIC using the S1,S2,S3 pins found on the board. I am currently using the RDK Basic reference design as a base for my own design that will be capable of both driving the motors and using the servo motors attached. Since this board is on its last legs and has been replaced by the new Chipkit board it is quite a bit harder to find proper documentation on the servo side of things. I have found references to a design called Cerebot32MX4_Servo_rd.zip and determined that this file was at one point hosted on the digilent servers. Unfortunately, I have not been able to track down a copy of it. It would be a great help if anyone could either provide me with a copy of said reference design or possibly some example code that can help with driving the servo motors. As far as I can tell the servo motors are driven via the bits 0-7 on PortB.

    Nexys 3/ PWM

    hello all, I am doing small class project. I would really appreciate if any one can help me with this. we are using SDK and we are trying to control servo which require PWM signal. I don't know how to generate PWM signal to control servo. I know it require two timers to do it. Thanks!!!
