1 Replies and 33 Views DM3730 ADC on Battery  33  1 Started by  David Simmons When USB is connected, I am able to set the CARKIT_ANA_CTRL register such that the analog pins 3-6 are connected to the ADC, and can read good values on ADCIN3 as expected.  However, when USB is not connected, and I am running off battery power only, I cannot manipulate the CARKIT_ANA_CTRL register.  That register always reads 0x20, and I can&39;t change it.

4 Replies and 174 Views DM3730 Torpedo with MT9J003 image sensor  174  4 Started by  Ryan Crowell We are interested in using the On Semiconductor MT9J003 image sensor with the DM3730 Torpeo SOM, and would like to gauge how much work this is going to be.  I believe the MT9P031 sensor is fully supported "out of the box", and the MT9J003 and MT9P031 sensors are similar to each other, though there are significant differences in the control register addressing.   I have seen references to Linux drivers for the MT9J003, though I&39;m not sure if there are any "offic...

4 Replies and 334 Views Accessing SPI on DM37xx dev board - Linux  334  4 Started by  Pratik Saripalli I am new to the platform and I am a little overwhelmed by the documents and I am having trouble getting my spi sensor to work. I&39;m running Linux 12.04 on the Torpedo with BSP 2.4-4. have been using spi-test as a base to try to understand and connect to my sensor. Initially i could not get spi-test to run the Acitivity board on SPI3 so I changed the dev to "spidev1.1" so that is would work on SPI1 and connect the SPI_CS1 for the chip select. I am then trying to modify the code...

1 Replies and 379 Views Channel 11 WiFi not working  379  1 Started by  Joshua Pagnotta We tried to update our hostapd config (we use the wireless performance base config for the BSP) to run on different wifi channels but noticed when trying channel 11 it does not work (we never see an SSID broadcast). It&39;s not readily apparent why this channel does not work as there are no errors indicating an issue, it just doesn&39;t create a WiFi network that we can see. Does channel 11 work with on the Torpedo SOM with the wifi performance BSP config

The other data lines and SCL,SDA line will be conencted to the  DM3730 Torpedo Kit. Can we go ahead with this approach 2)...
