Amazing 3.5″ Display Module powered by a PIC32
The Picadillo-35T is a 3.5″ 320×480 resolution (Half VGA) Embedded Display Module with Resistive Touch, featuring the Microchip PIC32MX795F512L 32bit microcontroller and Arduino / chipKIT style headers for easy attachment of shields, and compatible with UECIDE, MPIDE and MPLAB X Programming IDEs, making this a brilliant display solution with open source software.
The Picadillo-35T was designed with complete system control in mind. It features a 3.5″ display along with a ton of GPIO, making it a perfect candidate for system control which demands a GUI or user interface.
The PIC32MX795F512L is a powerful 32bit microcontroller from Microchip, which has 512Kb of Flash and 128Kb of SRAM, runs at 80Mhz and is capable of 105 DMIPS. It features a PMP graphics port which is used to connect the on board 3.5″ display, allowing for fast graphics fully controlled by the Users code. The same PIC32 is found on the popular chipKIT Max32 Development Board.
The Picadillo-35T has been designed to be programmed using the UECIDE IDE, which is based on the Arduino IDE however with various enhancements and improvements. It can also be used with MPIDE, or even using Microchip MPLAB X. Using UECIDE or MPIDE, the display module can essentially be treated as if it was a chipKIT MAX32 and programmed using the familiar programming language found on the Arduino/chipKIT.
UECIDE can be used to program Arduino boards as well as chipKIT boards, and is compatible with many existing Arduino and chipKIT libraries, allowing easy migration from existing boards!
The Picadillo-35T features an on board FTDI USB to TTL converter for programming and powering the display, along with an ICSP connection for using programmers such as the PICKIT3.
It also features an on board microSD connector, on board audio amplifier and speaker, RTC oscillator, and headers in the layout of the popular chipKIT Uno32.
If you can program the Arduino or the chipKIT range of products, or you want to get started, this product is for you. It features the best of the microcontroller platforms, coupled with a 3.5″ Display, Audio, microSD card and the familiar programming language.
The Picadillo-35T does NOT use the Workshop4 IDE. It uses UECIDE as the Primary IDE.

WORKSHOP4 IDE
Workshop4 is a comprehensive software IDE for Microsoft Windows that provides an integrated software development platform for all of the 4D family of processors and modules. The IDE combines the Editor, Compiler, Linker and Downloader to develop complete 4DGL application code.
All user application code is developed within the Workshop4 IDE.
DEVELOPMENT ENVIRONMENTS THAT SUITS ANY APPLICATION & USER LEVEL
Workshop4 includes four development environments for the user to choose based on application requirements or even user skill level.


WORKSHOP4 PRO
Make complex widget design, simple.
Smart Widgets Editor is a powerful utility which enables the generation of Smart Widgets.
GENIE MAGIC
Genie Magic is an extension to ViSi-Genie, which is available in Workshop4 PRO. Genie Magic allows the User to add 4DGL code to various points in the ViSi-Genie backend code, which allows Users to take full advantage of the power of 4DGL, while retaining the speed and convenience of ViSi-Genie and its defined communication protocol.
Genie Magic allows you to enter 4DGL code in the form of Events, Code and Objects, along with various touch related additions too, giving you to the power to achieve advanced GUI’s in ViSi-Genie without having to write the full code yourself.
Genie Magic is fully supported by the genieArduino and geniePi libraries, making communication with an Arduino or Raspberry Pi host even more powerful.
When using Genie Magic in combination with the Smart Widget Editor, it is possible to use the Smart Widgets Editor tool and Smart Widgets to create other graphical user interface elements such as:
