DuetWifi 2 and LIS3DH wiring

nuroo

This post got me up and running on a railcore. Had to change some pins in config setup to use daughter board spi. Im getting data thru the plugin as well. Looking forward to rrf 3.4

Just a quick info:
The picture of the adafruit LIS3DH on https://duet3d.dozuki.com/Wiki/Accelerometers is misleading because the V3.3 from the duet is connected to 3Vo (Output) instead of the VIN (Input) pin. Maybe it is better to remove it.

@mule Thanks. Do you mean this one? https://d17kynu4zpq5hy.cloudfront.net/igi/duet3d/Y1YiEWyeIEP5qi4Q
I see what you mean. I'll try and get @dc42 to take another picture. For now I'll put a note on the page.

@mule From @dc42:

connecting +3.3V from Duet to 3V0 is correct. In practice, connecting it to Vcc works too.
Connecting to Vcc would be necessary if we were using 5V supply

So I'll leave as is.

For me it did not work to connect +3.3V from duet to the output of the adafruit board. Maybe there are different boards with different layouts being sold by adafruit?

Glad my diagram helped!

I never got it working on the Duet2 WiFi, but have recently upgraded to a 3 Mini 5+ and trying again...

HI , I also have a duet wifi2 and just got my self an LIS3DH to try out, I was wondering if it was possible to use other pins then the temp board pins as it is in use already .
I do not use a screen or so .

thanks in advance for the help

@mrt no, you need to use hardware SPI pins. You can however use an accelerometer and 1 temp daughterboard. Just use the CS2 and CS3 pins
