![]() Hello All, here are some details (hope it can help). Hello, I have the same chip as you ti046b1 chip (Serial I2C F-RAM) (Dell laser printer with almost dead toner cartridge) I tried to read it with my raspberry Pi 3, so I connected SDA SCL VDD GND as shown in pictures, but when I run the command "i2cdetect -y 1" on my Raspberry it shows no device connected to I2C interface (empty) like that: $ i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: - 10: - 20: - 30: - 40: - 50: - 60: - 70: - do you have any idea to solve that ? - I tried by inverting SDA SLC connections - I tried by pulling-up to 3.3V SDA and SCL with 10k resistors (as stated ) could you please help me to solve that ? And to anticipate your first question : I checked all the connections for this wiring
