VM801P – FT801 Development Platform

The VM801P ‘Plus’ provides a comprehensive, full integrated, ready to use development system, designed to provide engineers with everything necessary to create quality Human Machine Interface (HMI) solutions with display, audio and capacitive touch functionality.

This fully Arduino-compatible module features an FT801 touch controller IC for three in one operation (display, audio and capacitive touch) controlled from an inbuilt ATMEGA328P microcontroller operating at 5V/16MHz. Programming and configuration is easily achieved via the Arduino IDE, using a pre-programmed Arduino-compatible bootloader, accessed from the on-board FT232R USB UART interface IC

The development system offers a hi-quality system with an elegantly designed, precision fit bezel that provides a capacitive multi-touch panel sensor and component board in a rugged, plastic enclosure. Offered in black (-BK) or pearl (-PL) colours, the device provides the engineer a low priced option which can shorten development time while enabling a production finished look for 4.3″ or 5″ colour TFT display solutions.

An abundance of enhanced features are included in the ‘Plus’ module: a backlit LED driver, inbuilt audio amplifier and micro-speaker, Real Time Clock (RTC) with battery backup, on-board 3.3v/5v level shifters, e-Flash IC build option, and a Micro-SD Card socket for application store plus 4GB SD card pre-loaded with 11 interactive application demonstrations and one library of free running apps, showcasing just a few examples of what this innovative device, designed primarily for industrial and commercial purpose, could be used for. The Arduino-compatible display system development platforms run off a standard 5V supply, delivered via a micro-USB or an auxiliary power connector. Furthermore, Micro-MaTch miniature connectors are provided to further extend functionality, and plug in card connectors are available to expand the IO capability to include GPIO, RS232, RS485, RELAY IO, Ethernet and POE, promoting improved connectivity and the ability to transmit over longer distances.

A complete listing of technical documentation is provided below. Due to the size of the documents and Sample Application software environment, Bridgetek recommends that purchasers of a VM801B development system, first acquaint themselves with the VM801B and FT801 datasheets, after which familiarity with EVE’s pseudo language found in the Programming Guide is advised. The remaining documents and Sample Application software have been developed with an orientation toward system and design implementation.

Application Architectures

Bridgetek supports two programming solutions for the VM801P module, the HAL and the Arduino libraries. The architecture of both development systems can be seen within the block diagrams below:

The first diagram portrays a sample application using the HAL structure, which is further detailed in Application Note 246 – VM800CB SampleApp Arduino Introduction. The sample application is designed to easily port to numerous MCUs over SPI by introducing one generic Hardware Abstraction Layer (HAL), which can then be used as a guideline for other platforms.

Alternatively, by utilising the Arduino library as outlined in Application Note 318 – Arduino Library For FT800 Series the engineer benefits from dedicated library support and examples, and can operate over the popular and easy to use Arduino IDE, using a pre-programmed Arduino Bootloader.

There is an FTDI FT232R chip on the VM801P module and the FT232R datasheet is available here.
Please install the VCP and D2XX driver by the setup executable and it is available here.
