Hi,

I'm trying to get my project to work and one of the problems is that data I write to a control register is not showing up on the pins the register is connected to (called DataOut in the project). While trying to figure it out, I noticed that my AddressBus and DataBus pin components don't show the pin assignments for each of their pins, even though all the pins are locked. They show the assignment for one of the pins, though.

I've attached the project. Can anyone advise me as to what I've done wrong? This is my first PSoC project, so it may very well be a N00B mistake. (There's debugging stuff in this project, like hard-coded writes to DataOut_Control and an OR gate forcing the DataBus' OutputEnable high. They're just part of my efforts to get this thing working.)

Thank you,

  Bob

I went through your project. The DataBus pins which are read by the StatusRegister (DataIn) need to be configured as Strong Drive. I have modified the project to use one of the pins of the ControlRegister (DataOut) to blink an LED to demonstrate that writing to the ControlRegister works correctly,

Please find the modified project attached.

I didn't quite understand the pin assignment problem you were facing. You can manually assign whatever pins you like by clicking the dropdown. Please elaborate on the issue.

Regards,

Dheeraj
