Posted: Thu Mar 29, 2012 1:45 pm Post subject: Alerts
I am trying modify some of the alerts so that I can use them for other purposes in the FPGA. It seems straight forward, but I have only been able to get Alert 1- software driven alert to work.
I tried modifying the DAC trigger alert by setting the Alert(25) to a 1hz counter instead of the dac_alert signals. Then I set Alert_Data(25) to a value like 0xBA55. When I run the Wave example project and I enable the trigger alert check box I would expect to see a printout with 0xBA55 in it every 1s but I dont. I verified with a logic analyzer that the 1hz signal is correct, and when I do the same thing with Alert(1) everything works.
Is there something with the alerts that I am missing? _________________ JS

There are two aspects to adding a custom alert: Firmware and software. So, even though you may have modified the firmware properly to generate a custom alert, it sounds like you have not handled the software requirements.
