Yes, the temperature won't change in milliseconds. But continuous monitoring is required for understanding the trend of failures. The temperatures at busbar and cable joints needs to be monitored. On Friday, February 17, 2017 at 10:11:36 AM UTC+5:30, john3909 wrote: > > Again, switchgear is

Re: [beagleboard] why is pinmux-helper needed?

The pinmux helper driver is required because modifying the pinmux settings must be done in the kernel. The helper exports sysfs entries that can be modified by standard user-mode code. Also, the pinmux helper provides a way to support multiple pinmux options, vs. a typical device tree where pins

[beagleboard] Connect two beaglebone wirelessly

Hello everybody. I'm an engineering student and for my final thesis I will work with the beaglebone black. The project is aimed to allow two beaglebone black to communicate wirelessly in real-time. The data that has to be transmitted will come from an ethernet cable, using Powerlink

Re: [beagleboard] Real time application development for BBB

So that tells me you need to stream the temperature measurements, which is what the AM335x ADC IIO driver does. Currently the driver is sampling at 800 ksps, but you can modify the sampling rate in the ADC overlay. Regards, John > On Mar 2, 2017, at 2:51 AM, avni gupta
