The programmer uses a firmware-only USB driver, no special USB controller is needed. Features Works under multiple platforms. Linux, Mac OS X and Windows are tested. No special controllers or smd components are needed. Programming speed is up to 5kBytes/sec. SCK option to support targets with low clock speed (< 1,5MHz). Planned: serial interface to target (e.g. for debugging). Download Firmware and circuit The following packages include circuit and firmware Drivers On Linux and MacOS X no kernel driver is needed.
