I start work on controlling the motor of my robot with HB-25 and the issue come up. I use myRIO (NI hardware with RT and FPGA) to control motor and read encoder back. I use motor in this link https://www.parallax.com/product/570-00080
. I completed the module to send PMW to control the motors and tested. Both of motors run as expected. Then while I start work on encoder, some how motor stop running. Since this is FPGA, I cannot find any reason why the module to control motor stop working. The LED next to power input has green color.
Could you please give me some hint to debug the issue?
