Noritake Itron has introduced a range of Ismart TFT modules to enable users to develop applications in a few days with limited experience of TFTs or programming.

The modules can run as a host or support serial interfaces with 8-bit CPU hosts where communication traffic needs to be a minimum.

This is achieved using an object-oriented programming language.

The 4.3in version has 24-bit colour with 100 pages of display RAM, 128MByte on-board flash and 4G+ SDHC card slot, giving it many of the attributes associated with a PC-based TFT system but at 30 per cent of the cost.

Users can interface via RS232, RS485, SPI, I2C, Async and USB with a 1MHz CAN bus expander available.

The 24 user I/O can support a 144 ‘dual-press’ key matrix without the need for diodes.

The module also features a piezo sounder drive, two PWM and two analogue channels, plus AC97 stereo audio bus, a real-time clock with date, an analogue touch panel and integrated debugger and command trace.

The itrontft.com website provides ASCII and world fonts, button and background images, as well as application downloads that can be modified with just a text and image editor.
