Got some progress! Python / node can talk with i2c libmraa/upm now!

I see that in the Makefile linkit (fork) packages list are missing if you compare with the original Linkit makefile

[tcpipchip]

I added some kmod files and menuconfig changes

[tcpipchip]

More progress! Gpio maps (pin id number) are incorrect, if you usually use those defined by Seeed Linkit Smart 7688

I2c WORKING, GPIO WORKING...
Where is in the Kernel MAP to GPIOS ?
For example, pin = mraa.Gpio(30) access the gpio where i put a led. But, how i know physically where is this pin ? And where is this 30 specification ?

I do not have a target machine, so I can not pursue it in detail...

Well,
I am satisfied for a while because LIMRAA and LIBUPM works with node-red.

Can you help me with WIFI to MEDIATEK 7688 LINKIT ?

The OSS version driver should be included in OpenWrt.

[tcpipchip]

How do i include those files and where ?

[nxhack]

How did you build the your firmware of MT7688?

[tcpipchip]

[nxhack]

Which OpenWrt version?, repository?
Which linkit-smart-feed repository?

Do you mean that is a configuration error ?

AP-MODE works, CLIENT-MODE fails

[tcpipchip]

hi can you verify if node-node-red-contrib-gpio compiles for you ? Make menuconfig

[tcpipchip]

error on serialport...
