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:

I2C EEPROM pinout

SCL	1-	O	-20	3.3V
SDA	2-		-19
5V	3-		-18
5V	4-		-17	3.3V
5V	5-		-16	5V
5V	6-		-15	LED(5V)
GND	7-		-14	USB D+
5V	8-		-13	USB D-
3.3V	9-		-12	5V
Oscillator	10-		-11	Oscillator

GND	1-	O	-8	3.3V
GND	2-		-7	GND
GND	3-		-6	SCL
GND	4-		-5	SDA

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:

$ sigrok-cli -i rding_temper_i2c_usb_led_sensor_5s.sr -P i2c:sda=0:scl=1
i2c: "START" 
i2c: "ADDRESS READ" "0x4f"

i2c: "ACK"

i2c: "ACK" 
i2c: "STOP"
