Scroll PHAT HD i2c adress


#1

Hi there,

I would like to run several Scroll Phat HD(SPHD) on one raspi. Sadly the i2c adress is be pre-coded on the SPHD and in your lib.

def __init__(self, i2c, address=0x74, gamma_table=None).

Is there a way to change the i2c adress on the board or order boards with different adresses?

Regards,

Kai

Unfortunately not. You would have to set up multiple i2c busses and wire the Scroll pHAT HD boards accordingly.

Use the dtoverlay:

dtoverlay=i2c-gpio,i2c_gpio_sda=<data_pin>,i2c_gpio_scl=<clock_pin>,i2c_gpio_delay_us=4
