Re: i2cdetect doesn't catch ANY address (no device detection)

I would be tempted to buy blanks from Alibaba to be honest :lol: That link seems to be a Lexmark chip and not a Dell - they may be the same but I'm not putting any money on it. (Hate Dell printers) You could try altering the clock speed on the I2C bus as some chips support: 100 KHz 200 KHz 400 KHz ...

Re: i2cdetect doesn't catch ANY address (no device detection)

When you say ' I tried by inverting SDA SLC connections' do you mean swapping them or using a level inverter? Some of these chips use a 10-bit addressing scheme not an 8-bit one (for security) so you may need an external reader :twisted: the "inverting" that I did is a simple swapping :) Thank you ...

i2cdetect doesn't catch ANY address (no device detection)

Hello, I have 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 interfac...
