Hi, I'm looking for a cheap dev kit with an ARM Cortex CPU and both a 3-axis gyro and a 3-axis accelerometer. Anyone know of such a board ? I really don't need much else apart from the ability to drive 3 PWM channels as outputs. Project is a stabilised camera platform for use on a boat. Thanks, Boo
ARM Cortex dev kit with 3 axis Gyro + 3 axis accelerometer ?

Apparently there's an Arduino IMU out there, too. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

I use gcc, but commercial tools might suit you better. Clifford Heath

I may get one for me, though. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

This is a) directly supported by openocd and b) can be used later as a general purpose programmer/debugger for your own hardware I have several different ones (F2, F3, F4, F1L), a couple just waiting for a suitable project. -- John Devereux

I've ordered an STM32F3DISCOVERY from Mouser for the princel;y sum of �7.54 exc. It has exactly the facilities I was after. Many thanks, Boo

It looks to me like the F3 has this nice fancy sensor and the F4 just has an accelerometer, or am I looking at the wrong doc about the F4? I had thought of getting an F4 board since it's a more powerful CPU than the F3 while the board costs about the same, but the sensor makes the F3 much more interesting. From http://www.mouser.com/new/stmicroelectronics/stm-f3discovery/ : L3GD20, ST MEMs motion sensor, 3-axis digital output gyroscope LSM303DLHC, ST MEMs system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor Similarly from http://www.mouser.com/new/stmicroelectronics/stm32f4discovery/ : External application power supply: 3V and 5V LIS302DL, ST MEMS motion sensor, 3-axis digital output accelerometer MP45DT02, ST MEMS audio sensor, omnidirectional digital microphone CS43L22, audio DAC with integrated class D speaker driver It looks like the F3 board has the gyroscope and mag sensor, but the F4 has nicer audio stuff.
