For those wondering the same thing I was... can I update my firmware... from the site...
Can I upgrade the Run-DMD firmware myself?
Yes, if you have a PICKIT3 tool you can update the dsPIC33EP-type MCU on the Run-DMD.
Run-DMD boards RevA/B/F2/F3 has a “ICSP” connector that you can connect the PICKIT3 to. If you have another Run-DMD board revision you need to remove the MCU and place it in a separate dsPIC33 ICSP socket for upgrading, this socket is available in the run-dmd.com shop.
The firmware hex-files are available for download at run-dmd.com, please note the board revision and MCU type since they use different firmware hex-files!
If you have questions regarding how to use PICKIT3, please refer to the microchip.com website.
