PanTiltHat with Raspberry Pi Zero W


#1

Hi,
I am trying to use PanTilthat with Raspberry Pi Zero W. Latest Raspbian build.

The library installed ok but when I try any of the examples I get an error message saying “Failed to Write Byte”.

When I run i2cdetect -y 1 I get nothing. When I run i2cdetect -y 0 I do see results:
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: – -- – -- – -- – -- – -- – -- –
10: – -- – -- – -- – -- – -- – -- 1c – -- –
20: – -- – -- – -- – -- – -- – -- – -- – --
30: – -- – -- – -- – -- – -- – -- – -- – --
40: – -- – 43 – -- – -- – -- – -- – -- – --
50: – -- – -- – -- – -- – -- – -- – -- – --
60: – -- – -- – -- – -- – -- – -- – -- – --
70: – -- – -- – -- – --

Any suggestions?

The only i2c device on the Pan Tilt HAT is the PIC, at 0x15- so I reckon you’re seeing the result of random noise being interpreted as i2c signals there, unless you have other devices connected?

What sort of GPIO header are you using on your Pi Zero W, and is it fit securely?
