# SatCam
# SatCam - SSTV encoder for OV2640
SatCam in an SSTV encoder with OV2640 camera. It is based on STM32F446RET6 microcontroller. Supported SSTV modes are Robot36, Robot72, MP73 and MP115. SatCam was originally developed as a part of PSAT2 satellite project and later redesigned as a stand-alone module.

SatCam can be commanded from e.g. an APRS link, the UART works at 9600 8N1. It looks for 'SATCAMERA:' keyword, followed by a command. End of line is <CR>, <LF> or '{'. Empty lines and messages without proper keyword are ignored. All commands including the keyword are case insensitive. Example: 'SatCamera:sstv.live.73'<CR>.

Another way of using SatCam is to setup its initial configuration with UART and then use its input signals only.
