Newer versions of AsProgrammer (post-2021) have added support for FT232H and Arduino (via a provided sketch). Key Features

While ASProgrammer is excellent for its intended purpose, it does have limitations. The software focuses primarily on , and it intentionally does not support programming microcontrollers (such as AVR or PIC devices) directly. For those tasks, dedicated tools like AVRDUDE, the manufacturer’s programming software, or more comprehensive universal programmers are required.
