Serial API

Serial API allows an external application or device to communicate with the SimpleBGC controller via UART port. Each controller has several UART ports that can be used to send and receive Serial API commands. Commands may be used to request the actual system state and realtime data, change settings, control gimbal, trigger pin state, execute various actions, get access to internal EEPROM and I2C bus, and so forth. Besecam SimpleBGC32 GUI software uses the same Serial API to communicate with the board, which means that all of its functions may be implemented in third-party applications.
