The microcontroller used on the Ami18 is the Microchip PIC18F25K20, which has 32768 bytes of flash memory, 1536 bytes of RAM, and operates at 64MHz, which equates to 16 MIPS (Million Instructions per Second). The PIC micro has 25 universal Input / Outputs. 

There are nine 10-bit ADC (Analogue to Digital Converter) inputs, and two 10-bit PWM (Pulse Width Modulation) outputs, as well as two comparators, a USART (Universal Synchronous Asynchronous Receiver Transmitter), SPI (Serial Peripheral Interface), I2C (Inter-Integrated Circuit), and four timers, each with various internal operations attached to them.

Each of the microcontroller’s I/O lines are brought out for use with external devices such as LEDs, Servos, Potentiometers, LCDs etc. See also our selection of expansion boards Ami18 LCD Shield, Ami18 Proto Shield, Ami18 Graphic Shield and Ami18 I/O Shield. 

Programming

Easy operation, simply connect the USB port of the Ami18 to a computer or connect a power supply / battery to get started. The Ami18 presents itself as a standard serial port on the PC. The Ami18 can be programmed directly from the USB port, so there is no need for a special programmer. The board can also be programmed directly from the In Circuit Serial Programming (ICSP™) adapter compatible with Microchip PICkit™ 2 or PICkit™ 3  programmers.

Software

The board can be programmed with any PIC® language like C18, Swordfish, PICbasic and the free Proton Amicus18 software. The PIC18F25K20 on the board is supplied pre-burned with a boot loader program that allows user to upload new code without the use of an external hardware programmer.
