TinyBASIC for Raspberry Pi
TinyBASIC is a simple BASIC interpreter which allow beginners to easily get into programming
Installing
You need to install libsdl-gfx1.2-4 package before install TinyBASIC.
You need to install libsdl-gfx1.2-4 package before install TinyBASIC.
- SSH to Raspberry Pi and execute command below:
| sudo apt-get install libsdl-gfx1.2-4 |
- Download TinyBASIC deb file and save it to any location of computer
- Transfer the downloaded deb file from computer to /tmp folder of Raspberry Pi using WinSCP
- Execute command below to start install TinyBasic
| sudo dpkg -i /tmp/tinybasic_2.1-1_armhf.deb |

Changing the Tiny Arduino clock between 1MHz and 8MHz
This article shows how to make a simplest & cheapest Arduino. The clock speed is running at 1MHz even though you select 8MHz internal clock. This is because the Div8 fuses bit of the new ATtiny85 is enabled by default, therefore 8MHz divided by 8 is 1MHz. In order to resolve this problem, we nee to disable the Div8 fuse bit using a AVR programmer.
Here I provide a method to switch the Tiny Arduino clock speed between 1MHz and 8Mhz by using a Arduino Duemilanove as an ISP programmer.

Simplest and Cheapest Arduino
Here we use a ATTiny85 (can be ATTiny45, ATTiny44) to make an Arduino just for US3.00, so we name it as Tiny Arduino.
Tiny Arduino have only eight pins as shown in figure above, Pin4 is ground (Gnd), Pin8 is 5V (Vcc), Pin1 is Reset, Pin2 and Pin3 originally used to connecting the Crystal. In order to utilize all the IO, the internal oscillator (RC Oscillator) is used to replace the external clock which require a crystal. Therefore the Tiny Arduino is now come with five IO. Below shows the Arduino IO functions.
- There are five IO, each IO can be Input or Output
- Among the five IO, two of the IO can perform as PWM
- Among the five IO, three of the IO can perform as Analog Input
I2C may require to extend the features of Tiny Arduino.

最简单又最便宜的Arduino
这里我们打造一个US3.00的Arduino，只是使用一个ATTiny85(ATTiny45，ATTiny44都可以)，所以称它为Tiny Arduino。
Tiny Arduino只有八个接脚（Pin)，Pin4为接地(Gnd)，Pin8为5V(Vcc)，Pin1为复位(Reset)，Pin2和Pin3原本用来连接Crystal，为了要尽量用完全部IO，所以使用了内部振荡(RC Oscillator)，因此Tiny Arduino共有五个IO。以下是Tiny Arduino的功能。
- 五个IO，各个IO可以设成输入(Input)或者输出(Output)
- 其中两个IO可以设成PWM
- 其中三个IO可以设成Analog输入
如果功能不足够，可以通过I2C对外扩展
