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
- Main chip: Unknown, yet (markings were removed)
- Temperature sensor: Fairchild FM75 (datasheet), I2C slave address 0x4f
- I2C EEPROM: Unknown, yet (markings were removed), I2C slave address 0x50
- Oscillator: 6MHz
Main chip pinout:
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| SCL | SDA | 5V/high | 5V/high | 5V/high | 5V/high | GND | 5V/high | 3.3V | Oscillator | Oscillator | 5V/high | USB D- | USB D+ | LED (5V) | 5V | 3.3V | 3.3V |
I2C EEPROM pinout:
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|
| GND | GND | GND | GND | SDA | SCL | GND | 3.3V |
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 -a i2c:sda=0:scl=1 i2c: "START" i2c: "ADDRESS READ" "0x4f" i2c: "ACK" i2c: "DATA READ" "0x1d" i2c: "ACK" i2c: "DATA READ" "0x80" i2c: "ACK" i2c: "STOP"
$ sigrok-cli -i rding_temper_i2c_usb_led_sensor_5s.sr -a usb:dm=3:dp=4:signalling=low-speed usb: "SYNC INVALID!" "001001001100100" usb: "SYNC INVALID!"
