Miniscope-Wire-Free-DAQ

Wire-free DAQ is compatible with all previous generations of wired open-source UCLA Miniscopes, with a microSD card mounted on it for local data storage. Once the wire-free DAQ is powered on, an on-board SAME70 microcontroller (MCU) (ATSAME70N21A, Microchip) reads configuration data from the microSD card and then implements that configuration in the Miniscopes using the I2C protocol. Configuration parameters include excitation LED intensity, focus of the EWL, and frame rate, gain, and resolution window of the CMOS image sensor. The wire-free DAQ can be mounted directly onto the MiniLFOV’s housing or be worn as a backpack. A single 4 cm long thin coaxial cable connected the Miniscopes and wire-free DAQ carrying power and data.The wire-free DAQ uses an infrared (IR) remote control receiver to receive digital commands, encoded into a 38 KHz IR carrier frequency, from an IR transmitter to start and stop wire-free recording remotely. This implementation of IR communication allows for one-way, arbitrary, wireless data transfer to the wire-free DAQ and Miniscopes. Recording starts when the wire-free DAQ receives the IR start code sent from an off-the-shelf IR remote control (KIT-14677, SparkFun) or custom IR remote control transmitter. To use it make sure you have uploaded the newest Wire-free-DAQ Firmware.
