Hey everyone, I've been working on a project that's using a Technologic Systems TS4900 module as its core. For peripherals we've got two USB ports, ethernet, + sound and touchscreen. The board is running Debian jessie with The part I've been toiling away at is the touchscreen, which is a Newhaven NHD-7.0-800480EF-ASXV#-CTP. My first problem was finding a kernel driver and devi

I need a way to externally make it join a network. Externally means some software entity that does not initiate the connection process from within the device. That software entity could be a phone or ...

Hi, I was wondering if someone can explain to me what CPU virtualization means from the perspective of inside of a CPU. I mean, If I have a single core how I virtualized it? What parts and functions of a CPU I have to know (registers, MMU) for achieving this CPU virtualization function? Is there any "general" programming code that does this? Also, I wil try to explain it as much b

The first thing to think of is the firmware upgrade strategy of an electronic device with embedded software. There are a multitude of bootloader out there for different microcontrollers, physical communication links and features. I know it's difficult, but is there a somewhat standard firmware upgrade procedure/strategy/protocol? Some open approach that is followed by different vend...

My team is being asked to find out why a circuit is failing for no obvious reason. The circuit has a piezo buzzer (CEP2242 from CUI, Inc). The buzzer is driven by a MCU driven FET that completes a circuit like this: high side power 3.3V -> buzzer -> FET -> ground (BSS123LT1 FET on the low side). Does anybody have any experience with the possibility of a piezo buzzer generating dama
