I would like to know if I can control (change) the I2C addresses that the HAT is using. If I understood it correctly, 0x2c: CAP1166 and 0x54: SN3218 are the I2C addresses for the display and capacitive buttons.
I’m asking because I want to use it stacked on top of another board that can be specifically addressed over I2C as well, namely the Adafruit DC Stepper motor HAT (https://pinout.xyz/pinout/dc_stepper_motor_hat). That board is also designed to be stacked easily. I see that only the BCM2 (SDA) and BCM3 (SCL) pins are shared between the two boards and I’d very much like to use them together (https://pinout.xyz/pinout/display_o_tron_hat).
Right now, although I presume that they are having different I2C addreses by default, the Pimoroni Display-o-Tron HAT does not power on if it’s stacked on top of the other one. This might be due to power requirements (?) or to some conflicting I2C addreses. Any guidance would be greatly appreciated, even though I understand it’s not designed to worked stacked on top of other HATs.
Thank you! :)
