4D SYSTEMS PICadillo-35T Display Module 4.4. The Power Supplies 4. Powering the PICadillo-35T 4.1. USB Power The PICadillo-35T is able to be powered numerous ways, however the most common will be using the USB Mini jack, which is also used to program the display module. The PICadillo-35T runs off a 5.0V DC supply, and draws approximately 250mA using an average arrangement of features at any given time.
4D SYSTEMS PICadillo-35T Display Module 5.2. Programming with Microchip Dev Tools 5. Programming the PICadillo-35T 5.1. Programming with UECIDE UECIDE is the perfect programming environment for programming the PICadillo-35T using a standard USB Mini cable. UECIDE features the PICadillo-35T is its list of plugins which are available for download, so after a very simple setup, the IDE is ready to use with the PICadillo-35T. Please refer to the www.uecide.org website for further information.
4D SYSTEMS PICadillo-35T Display Module 6. GPIO on the PICadillo-35T 6.2. Serial Ports 6.1. GPIO Voltage Levels The PICadillo-35T makes available 4 Serial UART ports of the PIC32 for the User. The PICadillo-35T features a Microchip PIC32 microcontroller, which itself runs off 3.3V. Typically the Arduino range of development boards was 5.0V and therefore shields used 5.0V IO. The concern with development platforms that run 3.
4D SYSTEMS PICadillo-35T Display Module 6.3. SPI The PICadillo-35T features an on board microSD card connector, which communicates to the PIC32 via the SPI Bus. Please note that a microSD card which supports SPI is a requirement. microSD Card: The on board microSD connector uses the SPI2 port which is (SS2, SDI2, SDO2, SCK2) on the PIC32 microcontroller, RG9, RG7, RG8, RG6.
4D SYSTEMS PICadillo-35T Display Module 6.6. External Interrupts There are 5 External Interrupts available on the PICadillo-35T. Please take note that some are located on pins used for other functions, so decisions need to be made as to which is utilised for your application.
4D SYSTEMS PICadillo-35T Display Module 7. Additional Features 7.3. Touch Screen Interface 7.1. On Board Audio Amplifier The PICadillo-35T has a 4 wire touch screen interface. The following pins (2 Analog, 2 Digital) are used to interface to the 4 wire touch: The PICadillo-35T features an on-board amplifier, capable of driving up to 1W and up to a 4ohm speaker, or the small speaker found on board the module itself.
4D SYSTEMS PICadillo-35T Display Module Note: The Displays used are the highest rated ‘Grade A’ Displays, which allow for 0-4 defective pixels. A defective pixel could be solid Black (Dead), White, Red, Green or Blue. 8.2. Display Precautions • Avoid having to display the same image/object on the screen for lengthy periods of time. This will cause a burn-in which is a common problem with all types of display technologies. Blank the screen after a while or dim it very low by adjusting the contrast.
4D SYSTEMS PICadillo-35T Display Module Provided with the TFT Library, are a range of demo applications specifically written for the PICadillo35T, which demonstrate some of the features of the display module. A repository of Fonts is also available from Majenko Technologies, available for download from here: https://github.com/TFTFonts Other libraries, such as BMPFile, and Widgets are also available from Majenko Technologies TFTLibraries Github repository, which are compatible with the PICadillo-35T 9.3.
