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.

NOT RECOMMENDED FOR NEW DESIGNS

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.

Designer

Enables user to write 4DGL code to program the display module.
4DGL syntax is similar to C: no need to learn a new language.
4DGL is optimized for GOLDELOX, PICASO, PIXXI and DIABLO Controllers.

Visi

Aptly named, a visual programming experience as you develop the display.
Enables drag and drop of objects in a WYSIWYG editor.
Software generates 4DGL code for the graphics.

Visi-Genie

An advanced environment; no 4DGL coding Required.
Everything is automated.
Drag and drop objects on the display.
Code written automatically.

Serial

ransforms the module into a serial slave.
Control the module from any host microcontroller with a serial port.
All serial protocols and documentation are provided.

WORKSHOP4 PRO

Make complex widget design, simple.

Smart Widgets Editor is a powerful utility which enables the generation of Smart Widgets.

Users can create complex widgets with up to six layers, including the layer for the base image. The order of the layers can be arranged as desired.
Each layer can contain one or more images arranged in sequence that can be manipulated in a variety of ways. Image manipulation options include horizontal motion, vertical motion, and angular motion. Additionally, the transparency of a layer can be set.
Two or more layers can be linked to produce synchronized movements of images. This enables the generation of complex widgets with multiple moving parts. Clockwork feature is also supported. This enables users to quickly generate clock widgets.
Each layer can have a numeric part which can display numbers in various fonts and formats. Alternatively, the numeric part can be a fixed sequence of text.
The output frames can be utilized using any of the supported Workshop4 environments.

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:

Dropdown Menu
Side Menu
‘Carousel Slider’
List Box

Dock Menu
Quarter-Rotary Menu
Fading Slide-To-Unlock Button
Spectrum With Transparency
And Many Others
