Riverdi TFT display with FT801 controller

 

riverdi

If you are looking for a touchscreen LCD display for your next project you should take a look at Riverdi LCD solutions. Their aim is to produce innovative, high quality LCD solutions at affordable prices. They were kind enough to send us a sample of a FTDI FT801 controller LCD display along with their Arduino TFT shield to test out. This LCD display has a build in video engine that accelerates performance over standard TFT displays when used with low power MCUs.

EA DOGS displays – small by size, big by features

obr1742_1

Minimum power consumption, very good legibility and a lot of versions – these are the EA DOG displays.

When we speak about “versions” – in case of EADOG from company Electronic Assembly it means a lot of “glass” types (STM, FSTN, transflective,…) and what is unique – many s display + backlight combinations. Right thanks to this unique possibility to make your own combination display + backlight according to your needs make the EADOG series so versatile. We can find here extraordinarily thin and compact graphic and character displays:

  • 1×8 – 2×16 – 3×16 for +5V or +3.3V power supply
  • 4×10/2×10 – 4×20 for +3.3V
  • Graphic 102×32 .. 240×128 for +3.3V

Character displays are with the SPI interface, some are also with I2C, and 4/8 bit. Simple 3,3V or 5V power supply further simplifies their usage.
In the EADOG family can be found „S“, „M“, „L“ and „XL“ series (EADOGS, EADOGM,…). The smallest one – EADOGS is suitable even for miniature applications, where a place is precious, but still a display is desirable or necessary there. On stock we keep three graphic versions 102*64 px with 33,6*23,4 mm active area. The newest member in the family of these small displays is the EA DOGS104-A character display (4×10 with a small font or 2×10 with a big font), while the character height may be changed by software. EA DOGS104-A is in standard equipped with 3 character sets (EN, EU, cyrilic).

The easiest way how to start development is to use the EA 9780-3USB development board.

The Atmel SAM L22

20150819015938_AtmelSAML22

by Martin Cooke @ elektormagazine.com:

Atmel has recently announced the addition of the SAM L22 series to its family of secure, ARM® Cortex® M0+-based MCUs. These new devices offer a built-in, ultra-low power capacitive touch interface with a segment LCD controller that can deliver up to 320 segments. Typical applications for these controllers would include low-power devices such as thermostats, electric/gas/water meters, home control, medical and access systems.

Their inbuilt features make them suited to IoT applications and the SAM L22 series includes security capabilities to deliver 256-bit AES, cyclic redundancy check (CRC), true random number generator, Flash protection and tamper detection to ensure information is securely stored, delivered and accessible. The devices use Atmel’s proprietary picoPower® technologies for low power consumption and smart low-power peripherals that work independently of the CPU in sleep modes.

Shadowandy’s Arduino-based Dust Sensor project:

Put together a dust sensor using Arduino Mega 2560, Shinyei PPD42NS dust sensor and LCD shield.

The codes and wiring instructions for Arduino Mega 2560 and Shinyei PPD42NS is as follow. However, I did include Serial output so you can view the sampling results using Arduino IDE’s Serial Monitor (9600 bauds).

Programmable 8-character LCD module and digital voltmeter

volmeter

A programmable 8-character LCD module and digital voltmeter project from Tuxgraphics:

Our 3 digit LED digital voltmeter module has been quite successful over the years. This new LCD module is basically an advanced version with a lot more capabilities. You can power it with the same voltage source that your signal is derived from. You can load your own code into this module but it has even some nice features for people who just need a voltmeter module and don’t want to play with C-code.
