I am looking for a tool for regression testing a suite of equipment we are building. The current concept is that you create an input file (text/csv) to the tool specifying inputs to the system under test. The tool then captures the outputs from the system and records the inputs and outputs to an output file. The output is in the same ...
I'm designing a user interface for a large touchscreen device running Linux. What would be the best toolkit/developer kit/SDK to use? The only requirement is that its able to run on a semi-low performace device, and that there is a Linux version. Nice-to-haves would be build in support for effects/animations and a modern look-and-feel...
I'm working on an embedded Linux project that interfaces an ARM9 to a hardware video encoder chip, and writes the video out to SD card or USB stick. The software architecture involves a kernel driver that reads data into a pool of buffers, and a userland app that writes the data to a file on the mounted removable device. I am finding th...
In the vxWorks RTOS, there is a shell that allows you to issue command to your embedded system. The documentation refers to kernel shell, host shell and target shell. What is the difference between the three? ...
We have two tasks (T1 and T2) in our vxWorks embedded system that have the same priority (110). How does the regular vxWorks scheduler deal with this if both tasks are ready to run? Which task executes first? ...
I'm looking for an off-the-shelf 8-bit processor module or even an entire hardware platform you used in a design. You used this product and essentially put your software on it. If you could mention the processor type and vendor it would be great. A small summary of the platform characteristics would also be great (e.g. 2 serial port, 1 1...
It does not need to be a full fledged OS, but at least have multitasking capabilities (i.e. a scheduler). Please mention what processor architecture it works on. This is a survey, so exact capabilities are not really important. Think of this as being a place to look at for possibilities when your next 8-bit embedded project comes up......
Hi, I'm looking to learn about embedded programming (in C mainly, but I hope to brush up on my ASM as well) and I was wondering what the best platform would be. I have some experience in using Atmel AVR's and programming them with the stk500 and found that to be relatively easy. I especially like AVR Studio and the debugger that lets y...
In an embedded application, we have a table describing the various address ranges that are valid on out target board. This table is used to setup the MMU. The RAM address range is marked as cacheable, but other regions are marked at not cacheable. Why is that? ...
Is there a way to control the Fujitsu Softune debugger with an other application(e.g. Eclipse)? I think about sending the command mentioned in the documentation of Softune and parse the output, but also other approaches are welcome. ...
We are starting a new project based a microchip PIC18F252. What is the best 'c' compiler to use? ...
I've been working on an embedded C/C++ project recently using the shell in Tornado 2 as a way of debugging what's going on in our kit. The only problem with this approach is that it's a complicated system and as a result, has a fair bit of output. Tornado 'helpfully' scrolls the window every time some new information arrives which means ...
I have an existing codebase targeting a Windows environment and with an eye to the future, would like to make this as cross platform as possible. I've had some sucess with standard Linux distributions by using cross platform libraries but would like to extend this to Realtime and or embedded operating systems. Would it be possible to po...
Excluding the Micro Framework Emulator ;) ...
For someone wanting to learn the rudiments of embedded programming, what are some simple projects they could tackle? We're talking about someone that does know the basics of electronic circuitry (resistors, capacitors, digital ICs, etc...) and can do basic soldering. An electronics hobbyist that is looking to get into embedded programmi...
I've been involved in embedded operating systems of one flavor or another, and have generally had to work with whatever the legacy system had. Now I have the chance to start from scratch on a new embedded project. The primary constraints on the system are: It needs a web-based interface. Inputs are required to be processed in real-ti...
Has anyone had success automating testing directly on embedded hardware? Specifically, I am thinking of automating a battery of unit tests for hardware layer modules. We need to have greater confidence in our hardware layer code. A lot of our projects use interrupt driven timers, ADCs, serial io, serial SPI devices (flash memory) etc.. ...
On a small embedded system project we have some code which we would like to run in a thread so we are electing to build in top of an embedded RTOS (eCos). Previously, we have used a cyclic executive in main() that drove tasks each implemented as a state machine. For some tasks we encountered problems where the task would need to be bro...
We have a vxWorks design which requires one task to process both high and low priority messages sent over two message queues. The messages for a given priority have to be processed in FIFO order. For example, process all the high priority messages in the order they were received, then process the low priority messages. If there is no...
After reading the Test-and-Set Wikipedia entry, I am still left with the question "What would a Test-and-Set be used for?" I realize that you can use it to implement Mutex (as described in wikipedia), but what other uses does it have? ...
