Hello,
During the development of a signal generator code on a Tmote Mini, I am experiencing some problems with the settings for the DAC, DMA and Timer components. I used the file TestDAC12DMAM.nc as an example to create my own code to output a selection of different frequencies to the DAC output of the Tmote Mini. This works all right for 50Hz (sine_period variable of 100), but when using a higher frequency, such as 100 or 250Hz, the sinus generated and read out by an oscilloscope (hardware device, not the oscilloscope app supplied by moteiv), doesn't seem to be correct. After searching for a period of several days on the internet, I conclude that there is very few information about this particular subject. Is there any information available about the DAC, DMA and the use of TimerExclusive together? The nesdoc documentation is incomplete so not an option. I would really appreciate the fact if someone could supply this information. Thanks in advance! j.kloosterman
