i have a problem: i only have on uc, an arduino, and have to build a tx unit with some cheap ebay radio modules. does anyone have any suggestions as to a small microcontroller for this unit. it only needs 2 or 3 channels.
4 weeks ago i ordered the dc-ss503 magnetic sensor module with tilt compensation, and i'm now trying to interface it with arduino. so far i have obtained the 4 values from the i2c bus, but i can't understand how to actually get a heading from it. this is the datasheet i found, which i know is the right one: http://gongxue.cn/lixueyuan/UploadFiles_8285/201004/2010042114001679.pdf .
does anyone have any experience with this module and can possibly help me? thanks
