Hi guys,
i even get frusttrated with this Edison stuff here on my desk and the usage of these I2C Port Expanders...
Port Expanders are no problem in general and I used them much times before on other MCU Projects, but if there is no Information on how the drivers are implemented you end up searching the web instead of being productive.
I even read the Emutex Labs Summary on that GPIO, PWM and ADC usage - much thanks from my side for this work - but it does not work so far.
Looking at Example 3 setting up PWM on IO6 : I have NO gpio214 and even NO gpio254 or gpio222 in my /sys/class/gpio path ?!
I updated my Edison yesterday with the image from intel (edison-image-rel1-maint-rel1-ww42-14.zip) and I can not say if these devices have been there before.
But actually I am not able to get the examples run and even the Arduino IDE Examples for the Peripherals do not work, except the LED Blinky.
So we have to go into detail debugging the I2C Data between Port Expanders and Edison to get it run, or we have to wait for intel doing the job on documentation ?
Happy Beta-testing, isn't it ?
Kind regards,
Marcus
