Development Board, it is first necessary to have a 1. Plug In Module PIM installed on the male headers U1. A. A PIM is always required, as the microcontroller U1. PIM area is part of the PICkit On Board programmerdebugger circuit, and is therefore not intended for running application related code. A list of available 1. PIMs which are compatible with the Explorer 1. Explorer 1. 6 Development Board can be found at http www. To begin development and programming the PIM microcontroller and using the hardware of the Explorer 1. Development board, it is recommended to obtain the MPLAB Integrated Development Environment IDE and a suitable C compiler supporting your desired target PIM microcontroller. MPLAB X IDE and MPLAB C compilers can be found at http www. Microchip provides a wide variety of free example firmware projects and libraries, which are compatible with the Explorer 1. Development Board. Some initial out of box demo projects are available from http www. Explorer. 16. 32. These demos exercise and demonstrate the basic functionality of the Explorer 1. Development Board and the microcontroller e. ADC data to the LCD module. Details on the usage of the example projects can be found in the documentation accompanying the projects. Application and microcontroller peripheral interface code can be generated using the MPLAB Code Configurator MCC http www. Additional reference projectslibraries compatible with the Explorer 1. Development Board can be found in the Microchip Libraries for Applications MLA and Harmony packages http www. Harmony. Tips for Reading the Schematics. The net names of signals connecting to the PIM microcontroller headers U1. A follow a naming convention where each net except power and ground is prefixed with Pxx where xx is a number 1 1. The Pxx number corresponds with the U1. A male PIM header pin number associated with the net. Nets that are also connected to one or more dedicated hardware features on the Explorer 1. Development Board have net names with underscores and suffixes denoting their associated features. For example, the net P2. TEMP is the electrical signal attached to the U1. A male PIM header pin 2. TC1. 04. 7A temperature sensor U4 on the Explorer 1. Development Board. Similarly, the net P9. S5LED1. 0 represents the signal attached to U1. A male PIM header pin 9. S5, as well as LED D1. Explorer 1. 63. 2 Development Board. It is important to note that the U1. A male PIM header pin numbers usually do NOT correspond 1 1 with the pin numbers of the microcontroller mounted on the PIM PCB. For example, the PIC2. FJ2. 56. GA7. 05 PIM MA2. TQFP 4. 8 microcontroller, which does not have enough total IO pins to connect to and control all 1. PIM pins independently especially in a 1 1 fashion. Therefore, the PIM PCB maps microcontroller pins to PIM header pins on a functional basis ex PIM pin 2. P2. 1TEMP is connected to an AD input channel pin RA1AN1 on the microcontroller, which is TQFP 4. We recommend you refer to both the PIM schematics as well as the Explorer 1. Development Board schematics when tracing signals between the microcontroller IO pins and the connected hardware. In addition to the above conventions, the signal names for dedicated signals connecting to the mikro. BUS interfaces end in A or B. For example, the net P1. SCKA connects to U1. PIC microcontroller Wikipedia. PIC microcontrollers in DIP and QFN packages. PDIP PIC2. 4 microcontroller next to a metric ruler. PIC usually pronounced as pick is a family of microcontrollers made by Microchip Technology, derived from the PIC1. General Instruments Microelectronics Division. The name PIC initially referred to Peripheral Interface Controller. The first parts of the family were available in 1. Early models of PIC had read only memory ROM or field programmable EPROM for program storage, some with provision for erasing memory. All current models use flash memory for program storage, and newer models allow the PIC to reprogram itself. Program memory and data memory are separated. Data memory is 8 bit, 1. San Andreas Multiplayer Hacking Programs more. Program instructions vary in bit count by family of PIC, and may be 1. The instruction set also varies by model, with more powerful chips adding instructions for digital signal processing functions. The hardware capabilities of PIC devices range from 6 pin SMD, 8 pin DIP chips up to 1. SMD chips, with discrete IO pins, ADC and DAC modules, and communications ports such as UART, I2. C, CAN, and even USB. Low power and high speed variations exist for many types. The manufacturer supplies computer software for development known as MPLAB X, assemblers and CC compilers, and programmerdebugger hardware under the MPLAB and PICKit series. Third party and some open source tools are also available. Some parts have in circuit programming capability low cost development programmers are available as well as high production programmers. PIC devices are popular with both industrial developers and hobbyists due to their low cost, wide availability, large user base, extensive collection of application notes, availability of low cost or free development tools, serial programming, and re programmable Flash memory capability. Historyedit. Various older EPROM PIC microcontrollers. The original PIC was intended to be used with General Instruments new CP1. CPU. Whilst most people considered the CP1. CPU, it had poor IO performance, and the 8 bit PIC was developed in 1. IO tasks from the CPU. The PIC used simple microcode stored in ROM to perform its tasks, and although the term RISC was not used at the time, it shares some common features with RISC designs. In 1. 98. 5, General Instrument sold their microelectronics division and the new owners cancelled almost everything which by this time was mostly out of date. The PIC, however, was upgraded with an internal EPROM to produce a programmable channel controller. In 2. 00. 1, Microchip introduced Flash programmable devices, with full production commencing in 2. Today, a huge variety of PICs are available with various on board peripherals serial communication modules, UARTs, motor control kernels, etc. K words and more a word is one assembly language instruction, varying in length from 8 to 1. PIC micro family. PIC and PICmicro are registered trademarks of Microchip Technology. It is generally thought that PIC stands for Peripheral Interface Controller, although General Instruments original acronym for the initial PIC1. PIC1. 65. 0 devices was Programmable Interface Controller. The acronym was quickly replaced with Programmable Intelligent Computer. The Microchip 1. C8. PIC1. 6x. 84, introduced in 1. Microchip CPU with on chip EEPROM memory. By 2. 01. 3, Microchip was shipping over one billion PIC microcontrollers every year. Device familieseditPIC micro chips are designed with a Harvard architecture, and are offered in various device families. The baseline and mid range families use 8 bit wide data memory, and the high end families use 1. The latest series, PIC3. MZ is a 3. 2 bit MIPS based microcontroller. Instruction words are in sizes of 1. PIC1. 0 and PIC1. PIC1. 6 and 2. 4 bit PIC2. PIC. The binary representations of the machine instructions vary by family and are shown in PIC instruction listings. Within these families, devices may be designated PICnn. Cxxx CMOS or PICnn. Fxxx Flash. C devices are generally classified as Not suitable for new development not actively promoted by Microchip. The program memory of C devices is variously described as OTP, ROM, or EEPROM. As of October 2. 01. OTP product classified as In production is the pic. HV5. 40. C devices with quartz windows for erasure, are in general no longer available. PIC1. 0 and PIC1. These devices feature a 1. They are represented by the PIC1. PIC1. 2 and PIC1. Baseline devices are available in 6 pin to 4. Generally the first 7 to 9 bytes of the register file are special purpose registers, and the remaining bytes are general purpose RAM. You Set Me Angie Miller more. Pointers are implemented using a register pair after writing an address to the FSR file select register, the INDF indirect f register becomes an alias for the addressed register. If banked RAM is implemented, the bank number is selected by the high 3 bits of the FSR. This affects register numbers 1. Because of the very limited register space 5 bits, 4 rarely read registers were not assigned addresses, but written by special instructions OPTION and TRIS. The ROM address space is 5. CALL and GOTO instructions specify the low 9 bits of the new code location additional high order bits are taken from the status register. Note that a CALL instruction only includes 8 bits of address, and may only specify addresses in the first half of each 5. Lookup tables are implemented using a computed GOTO assignment to PCL register into a table of RETLW instructions. This baseline core does not support interrupts all IO must be polled. There are some enhanced baseline variants with interrupt support and a four level call stack. PIC1. 0F3. 2x devices feature a mid range 1. SRAM register file, and an 8 level deep hardware stack. These devices are available in 6 pin SMD and 8 pin DIP packages with two pins unused. One input only and three IO pins are available. A complex set of interrupts are available. Clocks are an internal calibrated high frequency oscillator of 1. MHz with a choice of selectable speeds via software and a 3. Hz low power source. These devices feature a 1. The instruction set differs very little from the baseline devices, but the two additional opcode bits allow 1. There are a few additional miscellaneous instructions, and two additional 8 bit literal instructions, add and subtract. The mid range core is available in the majority of devices labeled PIC1. PIC1. 6. The first 3. RAM. If banked RAM is used, the high 1. F are global, as are a few of the most important special purpose registers, including the STATUS register which holds the RAM bank select bits. The other global registers are FSR and INDF, the low 8 bits of the program counter PCL, the PC high preload register PCLATH, and the master interrupt control register INTCON. The PCLATH register supplies high order instruction address bits when the 8 bits supplied by a write to the PCL register, or the 1. GOTO or CALL instruction, is not sufficient to address the available ROM space. The 1. 7 series never became popular and has been superseded by the PIC1. The 1. 7 series is not recommended for new designs, and availability may be limited to users. Improvements over earlier cores are 1. PIC1. 7 devices were produced in packages from 4.
