#ACME-0010 SP AIR

##Configurazione Kernel

Nella directory di compilazione del Kernel Linux digitare:

<pre class="terminal">
wget https://www.acmesystems.it/www/SP-AIR/acme-spair_defconfig 
mv acme-spair_defconfig arch/arm/configs
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- acme-spair_defconfig
make -j8 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- zImage
scp arch/arm/boot/zImage root@192.168.1.10:/boot
make modules -j8 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
make modules_install INSTALL_MOD_PATH=./modules ARCH=arm
</pre>

* Defconfig da usare per compilare il Kernel [acme-spair_defconfig](./acme-spair_defconfig)

##Compilazione Device Tree

Nella directory di compilazione del Kernel Linux digitare:

<pre class="terminal">
wget https://www.acmesystems.it/www/SP-AIR/acme-spair.dts 
mv acme-spair.dts arch/arm/boot/dts
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- acme-spair.dtb
scp arch/arm/boot/dts/acme-spair.dtb root@192.168.1.10:/boot/at91-sama5d3_acqua.dtb

</pre>

* Sorgente device tree [acme-spair.dts](./acme-spair.dts)
* Compilato device tree da mettere nella prima partizione della microSD e rinominare in <b>at91-sama5d3_acqua.dtb</b> [acme-spair.dtb](./acme-spair.dtb)

##Uso delle linee GPIO


|             | Pin Acqua      | Pin MCU     | Kernel ID        | Active state | Reset state |
|-------------|-------|------|---------|-|-|
| LED1        | J2-33 | PB8  | GPIO 40 | 1 = Led ON | Input - Led ON |
| LED2        | J2-37 | PB12 | GPIO 44 | 1 = Led ON | Input - Led ON |
| SWITCH1     | J2-16 | PB3  | GPIO 35 | 0 = Pulsante premuto | Input - Unpressed |
| WIFI POWER  | J1-39 | PA24 | GPIO 24 | 1 = WiFi ON  | Input  - WiFi OFF |
| MODEM POWER | J2-19 | PB10 | GPIO 42 | 1 = Modem ON | Input - Modem OFF |

##Set dei vari dispositivi

<pre class="terminal">
#Modem ON
echo 42 > /sys/class/gpio/export
echo out > /sys/class/gpio/pioB10/direction
echo 1 > /sys/class/gpio/pioB10/value
 
#Modem OFF
echo 0 > /sys/class/gpio/pioB10/value

#WiFi ON
echo 24 > /sys/class/gpio/export
echo out > /sys/class/gpio/pioA24/direction
echo 1 > /sys/class/gpio/pioA24/value

#WiFi OFF
echo 0 > /sys/class/gpio/pioA24/value

#Led On (first)
echo 40 > /sys/class/gpio/export
echo out > /sys/class/gpio/pioB8/direction
echo 1 > /sys/class/gpio/pioB8/value

#Led OFF
echo 0 > /sys/class/gpio/pioB8/value

#Led ON (second)
echo 44 > /sys/class/gpio/export
echo out > /sys/class/gpio/pioB12/direction
echo 1 > /sys/class/gpio/pioB12/value

#Led OFF
echo 0 > /sys/class/gpio/pioB12/value
 
#Rear panel switch
echo 35 > /sys/class/gpio/export
echo in > /sys/class/gpio/pioB3/direction
cat /sys/class/gpio/pioB3/value

</pre>

##Modem /dev/ttyUSB0,1,2,3

Per la gestione del modem i flag da abilitare nel kernel sono:

<pre class="minicom">
CONFIG_PPP
CONFIG_PPP_FILTER ß
CONFIG_PPP_ASYNC
CONFIG_USB_SERIAL
CONFIG_USB_SERIAL_GENERIC
CONFIG_USB_SERIAL_OPTION
</pre>

In questo modo vendono aperte quattro seriali:

<pre class="minicom">
/dev/ttyUSB0
/dev/ttyUSB1
/dev/ttyUSB2
/dev/ttyUSB3
</pre>

Per il PPP segui questo articolo @article='ppp'

## Yarm

La Yarm è collegata sulla porta <b>/dev/ttyS1</b>

## Porte seriali

Assegnazione delle porte seriale.
