How to modify DFU file to change frequency of STEVAL-IM009V1 waveforms

Hello,

I am using the STEVAL-IME009V1, and I would like to modify the factory settings ''STSW-IME009_May_2014.dfu'' file to output the demo waveforms at 60kHz instead of 5MHz.

Using the Dfu file manager, I extracted the DFU file to a hex file, but I cannot find where the frequency for the programmable waveforms is specified. Any help would be greatly appreciated.

Thank you.

Hello, Charles,

As already answered thru internal mail tread, normally, when certain customers want to customize the .dfu, theyâ€™ve to provide us the patterns (new HV sequence states timing) in order to rebuild the IME009V1 programs stored flash memory on board. This meas to request a. dfu custom on demand to our lab. Once we generated the new .dfu, customer can do the .dfu file upload procedure thru a GUI via USB.
