Additional Information [Hide]

The PICAXE system is a powerful, low cost microcontroller programming system designed to simplify educational and hobbyist use of microcontrollers. PICAXE chips can be programmed in a graphical 'flow-chart' environment or in easy to understand BASIC.

PICAXE-20X2 microcontroller chip. Enhanced 20 pin microcontroller with individual pin control, 64MHz option and additional features including i2c/spi bus support.

  • Pins: 20
  • Memory (lines): 1000
  • I/O Pins: 17
  • Outputs/Inputs: 1-17 (Configurable)
  • ADC (L=low): 0-8
  • Data Memory: 128 +i2c+128 Scratch
  • Based on the PIC PIC18F14K22

Memory (lines) = Approximate number of lines of program code the chip can hold.
Data Memory = Bytes of EEPROM memory on board. "128 (-Prog)" means 128 Bytes less the space needed for your program. 256+I2C means 256 Bytes + any external EEPROM space you add via the I2C interface).
Polled Interrupt = A process that automatically checks a pin in between each command to see if something has happened (very useful!)
