I am so much excited to play with STM32F429I-DISCO board which is having an arm cortex m4 microcontroller with external RAM of 64Mbit. Also the most exciting part of the board is 2.4" QVGA TFT LCD and a gyro. The microcontroller is having 2MB and 256KB internal FLASH and RAM respectively.
I am planning to do many things on this board, like 3gp/mp4 video player (if possible,but not sure), oscilloscope with external high speed ADC, interactive video games, simple voice recognition, 3D rendering and many more. Also you can expect an article on how to develop applications on this board using completely free and open source tools (arm-none-eabi-xxx) in linux environment.
Ordered the board from element14 and eagerly waiting for it. Stay tuned, will be updating with exciting projects on STM32F429I-DISCO.
