ZoomIO RISC-V

ControlFreak
Sub microsecond BitBang scripting

Some applications like custom protocol simulation, precise measurement, and glitching need precision control with resolution of nanoseconds. ZoomIO provides a simple and quick way to do this - all compiled to native RISCV binary.

The on-device compiler targets the second core of the Main RP2350 or one of the cores synthesized in the FPGA. Total control with minimum effort - the most bit for the bang!

Optional cooperative multitasking is supported in ZoomIO letting you do up to 8 tasks in parallel.

The ZoomIO simulator is a tool provided for FREE-WILi 2 to test and simulate your ZoomIO scripts.
