I have 4 of the LP5569's on a PCB interfaced to an FT232HL in I2C to USB configuration. I have this connected to my laptop. I would like to download programming to the LP5569 but am not sure what tools I need to allow me to accomplish this. I saw on the application notes something referring to LASM.exe to create hex files. It also mentions a GUI. But I do not see this software anywhere on the website. Do I also need some sort of code compiler? I do not have the evaluation PCB.
