Why can't the e-ink screen be driven on some newer Raspberry Pi systems or the Raspberry Pi zero 2 w?

2024-07-12 15:04:05 The I2C bus rate for this e-ink is fixed at 100kbps. you need to check the /boot/firmware/config.txt file for the following line:dtparam=i2c_arm=on, and then add after this line: i2c_arm_baudrate=100000It has to be ended exactly like this:dtparam=i2c_arm=on,i2c_arm_baudrate=100000
