Our team enjoyed Embedded World 2012. We visited and talked to Raisonance and ST Microelectronics about assistive technology and microcontrollers. STM32F4 and IMU (gyro, accelerometer, magnetic compass, pressure and temperature sensor) extension boards for the EvoPrimer and STM32F4 Discovery kit was presented. It is great for us, we can use DSP instructions in advanced algorithms in embedded application.
