A10S GPIO under Android (Click Here to Download)

*) GPIO using ADB

1. Boot android (from NAND or SDcard)

2. Connect USB-to-Serial cable on UART1

3. Open terminal at speed 115200

4. When loading is ready in the terminal type "sh" and enter

5. "ls /sys/class/gpio_sw" will give you a list of all accessable GPIOs.

The GPIOs name is according to the chip ports. For example PE3 is LED1.

6. To set PE3 as output:

#echo 1 > /sys/class/gpio_sw/PE3/mul_sel

or as input

#echo 0 > /sys/class/gpio_sw/PE3/mul_sel

7. To turn on LED:

#echo 1 > /sys/class/gpio_sw/PE3/data

and to turn off:

#echo 0 > /sys/class/gpio_sw/PE3/data

8. If GPIO is as input to read state:

#cat /sys/class/gpio_sw/PE3/data

*) GPIO using Android SDK

Basicly you should read and write to the filesys. Make sure that your app is running as root, or else nothing will happen. The demo program toggle LED1 on every button press. All read/write methods are realized in GPIO.java file.

A Single-board computer (SBC) is complete computer on a single circuit board. See brochures

It contains all the features of a fully operational computer including a microprocessor, memory, and input/output. SBC are lighter, more compact in size, and much more power efficient than a multi-board computer such as a desktop Because an SBC is completely self-contained, they make use of a wide range of microprocessors and increased density for the integrated circuits used. They are ideal for industrial applications such as process and automation control, IoT applications, kiosks and training displays, complex robotic systems, and processor-intensive applications.

Here are some specs to look at when comparing various SBC:

CPU/Processor - Whenever you issue a command from an input device such as a gamepad, a mouse, or a keypad you're sending instructions to the CPU whose job is to process those commands. It's considered the brains because it does the figuring whenever you want the computer to do something. A processor's speed is measured in megahertz (MHz) for millions of instructions per second and giga hertz (GHz) for billions of instructions per second. Keep in mind that the actual speed of the computer varies depending on the individual components used and not just the processor!
RAM - Refers to your computer's short term memory. When the computer is turned off it disappears. It performs calculations for your computer and disappears when it's turned off. RAM is measured in megabytes (MB) or gigabytes (GB). It allows your computer to do multitask and run separate processes at the same time. The more RAM you have the less likely your computer is going to be sluggish when you are multi-tasking.
- DRAM (Dynamic Random Access Memory)
- SRAM (Static Random Access Memory)
ROM - This refers to read-only memory that does not disappear when your computer is turned off. It contains instructions that allow your
computer to boot up.
- PROM (Programmable Read-Only Memory)
- EPROM (Erasable Programmable Read-Only Memory)

*DRAM, SRAM are different types of RAM. PROM and EPROM are different types of ROM.

Navigating through the different features of these world of these boards can be intimidating. Use this guide to help identify the solution that is best for you:

Take a look at our catalog of single board computers to decide which one is best for you in your region:
