This is a follow on to my previous two posts Power managment on Beaglebone AM335x platform part 1 and Power management on Beaglebone part 2-Battery for the community IoT BSP at BeagleBone BSP. The first two parts I discussed the background of battery support and some of the hardware modifications that are needed for the BeagleBone Black platform. I also talked about the AM335x’s on chip analog to digital converter (A/D or ADC) and how it can be used to measure voltage signals like battery voltage. We developed an A/D converter driver and test program and integrated it into the BSP. The next step in the process is to pull it altogether by developing a battery driver. The battery driver will, of course, be dependent on the A/D driver so we must make sure the A/C driver is loaded first. We can do this by modifying the drivers “Order” setting. For example here are the ADC registry setting: IF BSP_AM33X_ADC [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\ADC1]     "Prefix"="AD ...

It has been well documented in the news group the Windows Embedded Developer Update (WEDU) tool is pretty much broken in Windows Embedded Compact 7.  Many times it will show this message stating there are no updates needed when in fact there are newer updates available.     You can still relaunch the installer from the Windows Control Panel installed programs or use the WindowsEmbeddedCompact7.exe install launcher to kick off a re-install/update. This seems to work and initially it will find what level install you have existing and what is available as indicated with the slider at the top of the screen, It will then ask you to accept some eula’s:   It will try to download the component and update packages from the internet. You also have the option to create an offline layout. All fine and good so far but then comes the gotcha. It will stall asking for a SharedSource component.   You can try clicking the “Allow downloading for all files.” but it will not work and it ...
