duncan999007 posted a topic in GeneralI'm using the FRC Gamepad Tool to load the TI-supplied firmware for a USD HID joystick with a KMA210 magnetic angle sensor. I have a voltage divider taking the KMA210's 5V max output to 3.3V, and when plugging in the MSP and checking the windows game controllers, an axis does respond when I turn a magnet near the sensor, but the reading is all over the place. Bouncing back and forth by 40% of the whole angle range. I've tried using an external 5V supply, tried changing the sampling on the ADC, the Vref, the clock multiplier, the wires, the input pin, just about everything. Does anyone have any advice?
Anyone experimenting with this or have any thoughts on how this could be done in Energia? I'd like to do something like this with my MAP pressure sensor thing, where the user could drag and drop (or software on the computer could save) 'tuning' files to the device and that the unit would use for mapping its pressure sensor to the DAC. If possible, I'd also like to extend this to applying firmware updates in a similar fashion.
lawrence_jeff posted a topic in GeneralFor those of you attempting to build USB devices I put together some Launchpad examples as well as a lab type walkthrough of how to create custom devices (mainly HID) Included 1) Examples ported to the Launchpad - Mouse, Keyboard, Composite 2) Updated HID header file with additional device and usage types 3) A new device type called usbdhidcustom - This allows you to make new devices with minimal code changes 4) A complete document in lab type format where you build a volume control device, a gamepad and a keyboard + mouse 5) Completed projects to go with the labs StellarisWare.zip
