Serial LCD Plus Contact Reference Design


Interfaces with contact controls and shows, engineered for rigorous environments, present effectivity and adaptableness.


Serial LCDs with contact capabilities have revolutionised how we work together with expertise, providing an intuitive and versatile interface very important for numerous functions. Their compact and built-in design saves beneficial area and simplifies the event course of, making them a cornerstone in each hobbyist and industrial electronics. These shows present an economical answer for interactive methods, permitting for dynamic consumer interfaces and quick suggestions that enhances the consumer expertise. With the power to customize and adapt to numerous wants, serial LCD touchscreens have grow to be indispensable in advancing accessible and user-friendly digital units.

Renesas’s Serial LCD + Contact reference design presents a consumer interface harking back to a microwave oven on a QVGA LCD module, seamlessly linked to an RX Household MCU by way of SPI. This design incorporates capacitive contact buttons and a slider composed of clear electrodes. These parts are designed to glow white in opposition to the black enclosure when backlit by LEDs, offering a stark, visually interesting distinction. 

Builders aiming to customize their initiatives with specific show capabilities and functionalities can select between two specialised variations of this design. The RX671 variant can show 16-bit color, making it an ideal match for methods needing Actual-Time Working Methods (RTOS) or cloud connectivity help. Then again, the RX140 mannequin affords a extra simple 4-bit grayscale show, concentrating on initiatives prioritising low energy consumption and cost-effectiveness. These choices permit builders to pick probably the most acceptable answer for his or her software wants.

The Graphical Consumer Interface (GUI) answer that utilises the Serial Peripheral Interface (SPI) affords a cost-effective different, particularly well-suited for functions with low-resolution shows. This streamlined method permits LCDs to be managed successfully utilizing merely 4 pins designated for the SPI interface. Builders can entry pattern applications that allow the analysis of each an exterior LCD module and the performance of contact sensors on a singular chip. Moreover, RX MCU customers can profit from a complimentary and light-weight GUI library supplied by a associate, enhancing the event expertise with out incurring further prices.

Renesas have examined this reference design. It comes with a Invoice of Materials BOM, schematics, and so forth. You’ll find further knowledge in regards to the reference design on the corporate’s web site. To learn extra about this reference design, click on right here.
