Writing bit 0 of register 0xB5 to ‘1’ will enable synchronous continuous strobe mode.
‘0’ is default and is asynchronous cont. strobe mode. A delay after the start of
integration, but before the first rising edge of synchronous continuous strobe can be
inserted up to 65535 µsec. This is done by writing the value in microseconds to
register 0xB6. Default is 0x00.
USB Command Descriptions
A detailed description of all Flame commands follows. While all commands are sent to EP1 over
the USB port, the byte sequence is command dependent. The general format is the first byte is
the command value and the additional bytes are command specific values.
