The intent of PICKitPlus is to facilitate the programming of any 8-bit PIC microcontroller using the PICkit™ 2 and PICkit™ 3 (ICSP) In-Circuit Debuggers/Programmers. The software extends the life of the existing PICkit2 and PICkit3 hardware devices by allowing them to work with the newer 8-bit PIC microcontrollers. The capabilities include:
The STK600 allows in-system programming from the PC via USB, leaving the RS-232 port available for the target microcontroller. A 4 pin header on the STK600 labeled 'RS-232 spare' can connect any TTL level USART port on the chip to an onboard MAX232 chip to translate the signals to RS-232 levels.
The RL78 family is an accumulator-based register-bank CISC instruction set architecture (ISA). [2] Although it has eight 8-bit registers or four 16-bit register pairs, essentially all arithmetic operations are performed on a single accumulator (the A register or AX register pair).
Dragon12-P Freescale HCS12/9S12 microcontroller project development board utilizing an HD44780-based LC display. Character LCDs use a 16-contact interface, commonly using pins or card edge connections on 0.1 inch (2.54 mm) centers. Those without backlights may have only 14 pins, omitting the two pins powering the light.
The Atmel AVR instruction set is the machine language for the Atmel AVR, a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996. The AVR was one of the first microcontroller families to use on-chip flash memory for program storage.
ELAN Microelectronics Corp. make a series of PICmicro-like microcontrollers with a 13-bit instruction word. [4] The instructions are mostly compatible with the mid-range 14-bit instruction set, but limited to a 6-bit register address (16 special-purpose registers and 48 bytes of RAM) and a 10-bit (1024 word) program space.
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
However, for newer microcontrollers, specifically PIC18F6XJXX/8XJXX microcontrollers families from Microchip Technology, entering into ICSP modes is a bit different. [3] Entering ICSP Program/Verify mode requires the following three steps: Voltage is briefly applied to the MCLR (master clear) pin. A 32-bit key sequence is presented on PGD.
