To modify the source-code made available through the PGA450Q1EVM-S firmware installer, download the Keil C51 Development Tool for all 8051 devices, which includes the uVision IDE required to open and edit the PGA450-Q1 project file. Keil products use a license management system. Without a current license, the product runs as an evaluation or lite edition which has a few limitations.
