Bridgetek EVE Series - Touch Enabled Graphical User Interfaces

BRT-Marketing

Bridgetek’s products include the EVE family of display controllers which make it easy to add attractive and fully featured touch-enabled graphical user interfaces to existing and new product designs.

To improve the user experience and functionality, EVE devices can be used to upgrade the user interface of a wide range of devices including industrial machines (industrial controllers, machine tools, elevators) and household appliances, and in consumer electronics devices and many more applications.

The flexibility of EVE series is that it can be driven by any low-cost MCU over SPI. This allows existing equipment / products to be easily upgraded by adding colour graphics and touch with minimal impact to the existing design.

Another advantage of the EVE series is the EVE Toolchain programming tools, which significantly facilitate and speed up the process of designing with displays, especially in the field of extensive graphical user interfaces.

Our family of MCUs are optimized for high-speed interface bridging tasks to a wide range of protocols including USB Host, USB Device, SD Host, Ethernet, SPI, I2C, DAC, ADC, PWM, CAN and Camera Interface, these are available on the Bridgetek.

We have a downloadable Free Toolchain with a wide range of examples and easy prototyping by using development modules.

    They do not provide displays. You can use any display you want as long as it has compatible interface: parallel RGB. Some other interfaces are possible with converters. For example their eval boards frequently have onboard converter for LVDS. Touch controllers have usualy I2C interface. Their chips contains blob for handling communication with some chips which highly simplify their usage. If you select display with unsupported touch controller you can try find patch on their forum, then you will upload blob of binary code and then you can get touches using the same simple interface. If you do not find patch enywhere, you need to handle communication with chip yourself.

    I wrote review of their eval board and chip few years ago: /products/roadtest/rv/roadtest_reviews/1498/bridgetek_embedded_v_2. SInce that time they extended offer by automotive variants of chips and added new chips with some new capabilities as well as cheaper chips with some reductions for reducing cost.

    BuyDisplay (nice name - straight to the point!) have round displays. I've not purchased round displays from BuyDisplay, but have purchased rectangular LCD screens (with and without touch) from them in the past. They seem reliable, and some of their displays are available for a long term.

    There's lots of source code around for many of the controllers they use (e.g. RA8875 chip is easy to drive), so there's tons of community support around (and nowadays sometimes community support is better than what firms offer themselves).

    For our product, we are testing ESP32C3 LCD kit. I am looking for something similar like that actually. Preferably with touch controller, the one I have mentioned doesn't come with touch interface.

    What sizes are you considering?

    This one is 1.28 inch with capacitive touch, and it seems very low cost. There's a larger 2.1 inch display with capacitive touch too, the price seems reasonable considering it's high resolution. Both of these have in-built well-known controller chips that would easily interface with ESP32 (or any microcontroller with SPI).

    Just to throw some ideas out in case they are interesting: another option (if the screen is too small for decent user experience with touch), if the design has space around the display, or below the display, then touch sensors would work well.  Then the user has lots of space for pressing (without the hassle of needing a panel with button holes cut out), and the edges of the circular display can indicate what those buttons will do (if the buttons need to support soft-features).

    Thank you very much! The 1.28" display looks nice and crisp. We prefer capacitive touch displays, preferably driven by ESP32. I think I'll give it a try. Alternative option is buying the STM32 dk board with touch display that was in roadtest few months ago. ESP32 makes it easier to update the entire UI design remotely using Wifi.
