Firmware for the VSD Mk2
This download package includes the HEX and ELF files for the new Variable Speed Drive for Induction Motors.
They contain the same code. It just depends on which version of the ST Micro software you use whether you have the option to flash the chip from a HEX or ELF file.
A separate source code package is available below. WARNING: do not modify/recompile the source code unless you have experience working with mains-powered/high-voltage DC systems and have enough experience to properly debug and test your changes.
