Product review: EasyPIC v7 development board

EasyPIC1

MikroElektronika, a Belgrade, Serbia-based company is well-known for producing quality software and hardware development tools for a wide range of microcontroller families, including PIC, AVR, and ARM processors. Their mikroC Pro for PIC has always been my favorite PIC compiler, and has been extensively used in my PIC tutorials and projects published on this website, for its ease of use and rich set of built-in library routines. Today, I am reviewing MikroElektronika’s EasyPIC v7, which is the latest PIC development board in their line of EasyPIC series. I would like to thank to Newark USA for providing the EasyPIC v7 board for completing this review.

Unpacking EasyPIC v7

EasyPIC v7 comes in a colorful and protective cardboard box that can also serve as a good storage for the development board for later use. The thing I liked most about it is that the box also contains color-printed schematics and illustrative user’s manual of EasyPIC v7 along with a DVD for installing the required drivers and programming applications. The DVD also contains demo versions of mikroElektronika’s compilers as well as plenty of code examples. The EasyPIC v7 board is packed inside an anti-static bag and an USB cable is also included in the package to connect the board to the PC.

Main Features Highlight

EasyPIC v7, like its predecessors, is designed for rapid prototyping and development with Microchip’s 8-bit microcontrollers. It supports over 350 PIC microcontrollers, including PIC10F, PIC12F, PIC16F, and PIC18F series, and contains 8 DIP sockets to accommodate 8-, 14-, 18-, 20-, 28-, and 40-pin count PIC MCUs. The printed circuit board of EasyPIC v7 is extra thick (~3mm) and of high quality with clearly labeled components and pin functions. The board comes with the PIC18F45K22 microcontroller plugged in by default. Here I have summarized the main features of the EasyPIC v7 development board.

Power supply

EasyPIC v7 has a 5.0V switching power supply on board along with a 3.3V regulated output. A jumper selection is provided to select between 3.3V and 5.0V power supply for operation. Thus, it can be used to develop applications for both 3.3V and 5.0V series PIC MCUs. The board can be powered through a DC barrel jack, screw terminal block, or directly through an USB cable.

On-board programmer

The EasyPIC v7 board contains mikroProg, which is an USB programmer and in-circuit debugger for 8-bit PIC MCUs, and currently support over 350 PIC MCUs. In-circuit debugging is supported by all of mikroElektronika’s compilers for PIC. The availability of on-board programmer and its integration with the compiler makes the prototyping much easier and faster. EasyPIC v7 is also equipped with an RJ-12 connector, which is compatible with Microchip’s ICD2 and ICD3 external programmers.

I/O port organization

Unlike many other development boards, where the availability of user LEDs and tact switches are either limited or fixed to some I/O ports, the EasyPIC v7 board offers full flexibility to developers by assigning an output LED and an input tact switch for each I/O pin. MikroElektronika’s theme for EasyPIC v7 is “Connectivity“, which is justified by the presence of three IDC10 male header connectors (two on right and one on left side of the board) and one single row soldering pads for each MCU port, thus enhancing the accessibility of each I/O pin. Tri-state DIP switches are also present to enable a 4.7K pull-up (VCC), pull-down (Gnd), or floating state on any desired PORT pin. Further, the port LEDs can be enabled or disabled through DIP switches on the board.

mikroBUS socket

The EasyPIC v7 “Connectivity” is further enhanced by the presence of two mikroBUS sockets on board. Each mikroBUS socket consists of two 1×8 female headers, which provide access to important peripheral pins of the PIC MCU, including SPI, UART, I2C, ADC, etc., as well as the power supply pins. It allows a simple Plug-and-Play solution for connecting mikroElektronika’s several dozens of accessory boards (called Click Boards) to EasyPIC v7. Click boards are available for adding GPS, WiFi, MP3 decoding, Bluetooth, CAN, IrDA, GSM, Ethernet, and tons of other capabilities to the EasyPIC v7 board.

Seven segment LED and LCD Displays

The EasyPIC v7 development board provides a secured connecting socket and necessary interface support for the HD44780-based 16×2 character LCD as well as the KS108 (or compatible) driven 128×64 pixel graphical LCD. The display contrast for both LCDs is adjustable through dedicated potentiometers. Underneath the GLCD is a touch panel controller circuit that supports a 4-wire resistive touch panel glass for the GLCD. Additionally, the EasyPIC v7 also contains four seven segment LED displays that are arranged to be driven through multiplexing technique.

Summary

EasyPIC v7 is one of the best PIC development boards I have ever come across for its high quality build, abundant I/O resources, highly flexible and configurable design, and support of a wide range of 8-bit PIC MCUs. The on board USB 2.0 mikroProg tool allows faster programming and real-time debugging of over 350 PIC microcontrollers. The presence of Microchip’s ICD2/3 compatible RJ-12 connector on board also allows users to use a third party programmer/debugger along with the Microchip’s MPLAB development tool. Tons of mikroElektronika’s accessory boards available in mikroBUS form factor further expands the capabilities of EasyPIC v7 beyond limits. The schematics manual and user’s guide included in the package explain very well all the on-board features and how to use them. EasyPIC v7 is a must have development board for both starters and experienced developers, and for all PIC lovers, in general.

  • A few things your readers should be aware of.

    The update rate for both the C-Compiler and MikroProg for PIC is getting slower and slower. The last interval between updates for the C-Compiler was over 14months, for MikroProg for PIC its 6 months and counting. There are also PIC’s that are out almost 2 years now that aren’t supported by their programmer.

    Now you may be saying who cares if they are updated, as long as they work. Well if you want to use newer PIC’s with their Compiler and programmer then you care. Newer PIC’s are typically cheaper and more feature rich for example.

    I think their boards are also overpriced and you can do much better usually directly from the microcontroller’s manufacture. The sole benefit to their tool chain is ease of use for noobs. Once you start to get more advanced the limitations of being essentially locked into their tool chain will be a nuisance.

    There are now all sorts of free/inexpensive tool-chains and low cost development boards particularly for ARM. I recommend you go to EEVBLOG forum and read numerous threads in which list of ARM specific tools are in abundance.

  • If I were to design a ‘PIC playground’, this is what it would look like. The board has just about everything you need to develop projects quickly, and it is easy to expand its capabilities, just in case you need more. As another commenter mentioned, it comes packed with plenty of informative examples, also MikroE has a website where developers from around the world share code and example projects and such. It was easy to set it up and get projects running right out of the box. In my opinion, this a perfect development board for hobbyists like me, and I can see how professionals could get a lot of benefit from it as as well. I would recommend the EasyPIC to anyone who enjoys working with PIC’s.

  • I recently purchased an EasyPic V7 fusion with both dspic and pic32, this is a realy powerfull developpement board. I have used it for testing some examples on the DVD such as mp3 player and ethernet control the touch TFT. Since while i’m looking for someone who is interessted to work together on some projects.

    Having : VisualTFT and microC Pro for pic32 and dspic

  • hello,

    this is a very nice board, i will still here to discover the price, especially for academic field,

    but, i didn’t saw an HDMI port , just USB and UART and others type ?

    thank you

  • Somehow a review does not do EasyPIC7 justice.

    You have to own one to appreciate how good it is.

    I am lucky enough to own one (along with many, many other mikroElektronika products) and I love it.

  • I’ve been using this development board for the last couple of years and really enjoy it. One of the nicest features was that the DVD provided sample code showing exactly how to use each feature on the board, so new users could get up to speed with it quickly. The well commented code also included several very valuable tip & techniques I was able to incorporate in my own projects. The on-board programmer works directly with their C Compiler adding many real-time testing tools. With their recent sales the price on this unit has become low enough that I would highly recommend it for any new embedded programmer as a way quickly learn the ins and outs of peripheral interfacing.
