STMicroelectronics, has gone further to help product designers prove their own ideas quickly and independently, by adding a rich range of features such as touchscreen, built-in audio and an extension connector to its series of self-contained handheld platforms for embedded design. This gadget was designed by Raisonance.
The latest STM32 Primer2 (User Manual Primer2) is about the size of a cellphone, and comes with a 128x160-pixel color touchscreen, a joystick/push button, extension connector and pre-loaded sample applications. There is also a built-in USB port, a MicroSD card slot, and other features, such as an accelerometer and an infrared transmitter/receiver, that allow users to quickly add numerous extra capabilities and functions to their applications. All of these components are easy to manage through the built-in software framework, the open-source CircleOS.
ST's STM32 Primer for collaborative embedded development allows users to quickly turn a concept into an attractive-looking demonstrator. This is increasingly important for today's product innovators, particularly when seeking independent funding. A range of existing applications and an online community (http://stm32circle.com/) of more than 7000 developers stimulate ideas and creativity. Using the STM32 Primer2, users can present a high-quality prototype, rather than a conventional engineering development board, to create a better first impression with minimal design-start investment.
The first STM32 Primer also called the circle, was introduced in late 2007 and offered a new ergonomic design featuring a 128x128-pixel screen. Over 10,000 units have been shipped. Building on this success, the STM32 Primer2 adds extra benefits such as the larger screen with touch sensing and a Lithium-ion battery with features for extended battery life.
At the same time as providing a turnkey solution ready to run sample applications, STM32 Primers come with the fully integrated Raisonance Ride7 IDE, no need for a USB-JTAG debugger as this is integrated. This allows embedded designers to use the Primer platform for complete development of complex end products programming the customer target application with RLink professional. All necessary design resources are included, including source code for the pre-loaded applications, as well as software libraries for peripherals such as MEMS position sensors, the touchscreen and embedded audio components of the STM32 Primer2. The STM32 Primer2 also has a 20-pin external connector allowing easy connection of external circuit boards.
The STM32 Primer2 enables product developers with diverse skills to access the power of ST's advanced 32-bit STM32 microcontroller, which is available in three families targeting cost-effective, high performance, or USB-based applications. Available devices have Flash memory ranging from 16KB to 512KB, and all models across all families are pin-compatible for maximum flexibility and easier design upgrades to existing products. In addition, STM32 developers can receive support from a dedicated web site (http://stm32circle.com/), which has more than 7000 registered users and provides technical resources, design-sharing opportunities, and discussion forums.
The stm32circle website is hosted and maintained by Raisonance, another indication of the close relationship between ST and Raisonance.
