RDing TEMPer

The RDing TEMPer is a USB-based temperature logger.

See RDing TEMPer/Info for more details (such as lsusb -vvv output) about the device.

Hardware

I2C, USB, LED

I2C/USB closeup

Main chip: Tenx TMU3101MS (datasheet)
- The markings were removed, but we're relatively sure it's this chip, due to lsusb and pin/feature matching (see below).
Temperature sensor: Fairchild FM75 (datasheet), I2C slave address 0x4f
I2C EEPROM: Unknown, yet (markings were removed), I2C slave address 0x50
Oscillator: 6MHz

Chip pinouts:

See these example sigrok captures for the I2C, USB, and LED traffic going on while the device is queried from the PC (see also screenshots on the right-hand side).

Example usage:

i2c: "ADDRESS READ" "0x4f"

i2c: "ACK" 
i2c: "STOP"
