Can anyone explain how the voltage output of a single pixel from this sensor is converted to an RGB value?

Thanks for your help.

Thanks. A factory reset took care of the LED issue.

What does it mean when the blue LED on the pyboard comes on and stays on following power cycle? I can turn it off using: blue = pyb.LED( 4 ) blue.off() but on successive power cycle the blue light comes on and stays on. I loaned my pyboard to a friend and since I got it back it has been in this state.

Thanks Turbinenreiter, I did not see this in the literature.

I created a pyboard driver for the ADS9850 DDS module. This $10 board will generate up to around 40 MHz sin wave output. If you are interested in the driver let me know (I don't have a github site yet).

I believe I now have the pyboard working with the BME280 sensor. The data seems to be slightly off compared to measurements. If you are interested to review the code and add it to your bitbucket site I will post it.

Great job! I am interested to use the same sensor with the pyboard. Will the driver require much change to work with the pyboard? If so, would you be willing to suggest the appropriate changes? Also, The original Adafruit driver sets the I2C address as: # BME280 default address. BME280_I2CADDR = 0x7...

this board -> ADS9850 DDS module

If anyone is interested, the following code works fine with the AD9850 DSP module. import pyb # Define GPIO pins DATA = pyb.Pin('Y1', pyb.Pin.OUT_PP) W_CLK = pyb.Pin('Y2', pyb.Pin.OUT_PP) FQ_UD = pyb.Pin('Y3', pyb.Pin.OUT_PP) RESET = pyb.Pin('Y4', pyb.Pin.OUT_PP) def SetPinLow(pin): pin.low() return...

Thanks. I'll try it out against the hardware tomorrow. Once working I'll submit the driver to the community.
