Project Demo MED-SPO2 - AN4327 Freescale

Former Member — Fri, 08 May 2015 04:07:31 GMT

Hello everyone. I have just bought MED-SPO2 kit with TWR-K53N512 TOWER SYSTEM. But I can't find the project and GUI in AN4327 document.

Can you send it to me? I need it.

Thank you very much.!

Wieso funktioniert der Quicklink für die Datei sensorboard/sensor_board_1128.zip nicht?

Why doesn't work the Quicklink for downloading the sensorboard/sensor_board_1128.zip file?

Reverse-engineered sensor.so with source

Former Member — Sat, 13 Sep 2014 07:30:13 GMT

I have reverse engineered the sensor.so so that it can be compiled for V1.0 (and V2.0) Raspberry Pi Boards.

The source is available here: https://github.com/larsch/rpi-mems-sensor

I found that sensor.so is based on the bcm2835 library (bcm2835: C library for Broadcom BCM 2835 as used in Raspberry Pi), and is actually in full GPL violation. The sensor-specific function are quite simple though and mostly consist of the register numbers and bus addresses needed to talk to the chip. This could be implemented from scratch using the datasheet. The chips don't really require a "driver" when done this way, as the program basically talks on the I2C bus directly via the bcm2835 library.

I've kept it so that everything works the same as the original sensor.so and it is fully compatible with the original Python Scripts (get them from http://git.oschina.net/embest/rpi_sensor_board.git). It is working perfectly on my V1.0 board with all three sensors here, but note that the bcm2835 library needs to be compiled specifically for the V1.0 board.

Can this board be used with java?

Hi,

I am currently trying to write a little program in java which would display information from the sensors on the board, but I am struggling with how i would do this in java compared to the python scripts provided which use the sensor.so file to communicate with the board.

Many thanks
