CANdence C1.0

High fidelity CAN DAQ tool, ensuring your datastream never misses a beat.

Protocols:

• CAN2.0A (stdID), CAN2.0B (extID)

Baudrates:

• 1000k, 800k, 500k, 250k, 125k, 100k, 50k, 20k, 10k.

• Time quanta / sample points:

SD Card Compatibility:

• SDHC / SDXC

• No size limit

Transceiver:

• Screw terminal connection from main board to Adafruit CanPal TJA1051/T3, easily and cheaply replaced.

• Compliant to AEC-Q100, IEC 61000-4-2 ESD, RoHS.

Input Tolerances:

• Common mode (CANH,L) tolerance = +-30V

• Receiver recessive voltage = -4V < Vr < 9V

• Receiver dominant voltage = 0.9V < Vd < 9V

• ESD protection = +-8kV at CANH/L

Bus Connection:

• No termination present (high impedance node - 30kR differential resistance (CANH/L))

• Transmit pin disconnected - no ability to drive the bus (ack, error frames etc.)

Timestamp:

• Equal to baudrate - eg. 1000kbps → 1us resolution

• u16 timer - rollover automatically parsed in conversion software

Data Recovery:

• Given improper termination, data can be recovered (with a max of 8192 frames lost at the end). Provided software facilitates this.

Output format:

• Proprietary binary string, consisting of [8by header][8by data], no padding. Compact format, ideal for large dataset analysis - AI/ML.

• Open source conversion software to .asc and .csv
