For working with the board there were used a special distributive Armbian "Jessie". As builds of OpenSCADA there have used the packages repository, mostly for the generic architecture ARMHF, for which performs regular building of OpenSCADA by the OpenSCADA automatic builder into the cross-compiling environment.
The board provides more low level buses (3xUART, 2xSPI, 2xI2C), despite its small size, and restricted GPIO in 16 pins which mostly used by the buses. The buses are standard but GPIO is a specific one for which we need to implement special support into the presented module DAQ.GPIO making it more unified one. Then following tasks about the board are planed:
- (+) implement GPIO support on OpenSCADA;
- (+) connect a device to the I2C bus;
- connect a device to the Serial bus;
- try to adapt 1Wire (DS9097) to the Serial buses and directly throw the GPIO;
