Title: How to generate PWM from the BRX
Post by: Kieutrang on August 28, 2019, 10:12:57 PM

After reading the help files etc. I can find no way to establish the parameters for PWM.  I think you have to get to the Heap Item but I'm totally lost.  Which Instruction is used for this purpose??  Not trying to do anything mechanical like axis. Just need a PWM pulse train. Thanks in advance.

If you are using Designer v2.5 or greater, use PWMOUT.  Otherwise you will need to use the heap structures.  See software help topic DMD0408 for more on how to use the structures.

Open BRX help with F1. Select the 'Search' tab on the upper left. Type in the DMDXXXX topic ID and hit Enter. Matching topics will show up in the topic list.
