Embedded systems interact in complex and strange ways with the system's peripherals. We're not downloading drivers from some vendor's web site, or relying on a vast infrastructure of OS support. Design a simple
At the top of the host stack are the MATLAB scripts that perform application specific data collection and control. The scripttest.m, show in Code Listing 1, is a simple example of how to use the MATLAB MEX interface to open, set parameters, and collect data from the MAX35103E...
Can I use communications ports to connect to embedded systems or microcontrollers? Yes, communications ports are commonly used to connect to embedded systems or microcontrollers for programming, debugging, and data transfer purposes. Many development boards and microcontroller platforms provide Communications...
your bytes leave the application layer on Host A and travel through the transport and network layers on Host A; then they go down to the physical medium, across the medium, and up again through the various lower levels to the application layer on Host B in much the same way. If...
acceleration in addition to granular firewalls managed by the device management and security control (DMSC) subsystem. Additionally, the dual Cortex-R5F MCU subsystem is available for general purpose use as two individual cores, or the cores can be used in lockstep for functional safety ...

In traditional init systems, service daemons are expected to start themselves from scripts. A script runs a daemon program, which detaches itself from the script and runs autonomously. To find the PID of a service daemon, you need to use ps or some other mechanism specific to the service....
I would use MMAP for data buffers instead of simple registers addressing. For addressing, in kernel space you have to: // old fashion sdev->regs = ioremap(mem_res->start, resource_size(mem_res)); // new API sdev->regs = devm_ioremap_resource(&pdev->dev, res); which gives you...
You're now about ready to build the platform. But first, since you'll need to use the Kernel Tracker in the next section of this article, Part 3: Debugging the Platform, you'll need to enable the Profiling kernel. To enable the Profiling kernel and event tracking ...
