Absolute Software has been providing programming services since August 2000.
We are a fresh, innovative company who can provide professional quality solutions to your programming service needs.
We can provide the simplest of resource support, or we can provide complete multi-processor solutions - no programming services job is too big or too small.
There are many programmers for PIC microcontrollers, ranging from the simple designs which rely on In Circuit Serial Programming (ICSP) that allows direct download of code from a host computer to the more complex types of intelligent programmers that can verify the device at several supply voltages.
These programming hardware use a programmed PIC themselves to send the programming commands to the target PIC being programmed. The intelligent type of programmer is needed to program earlier PIC models which do not support in-circuit programming.
Microchip programmers include the following types...
PICStart Plus: RS232 serial
Promate II: RS232 serial
MPLAB PM3: RS232 serial and USB
ICD2: RS232 serial and USB
PICKit 1: USB
PICKit 2: USB
8 and 16 bit microcontroller are associated with different families where an "F" in the name of the product indicates the PIC uses flash and can be erased electronically. "C" in the name indicates that it can only be erased by exposing the die to ultraviolet light (these pics must have glass windows). The following demonstrates this...
8-bit Microcontrollers:
* PIC10 * PIC12 * PIC14 * PIC16 * PIC17 * PIC18
16-bit Microcontrollers:
* PIC24
16-bit Digital Signal Controllers:
* dsPIC30 * dsPIC33F
