Hi, I'm more of a hardware guy so I'm not sure if I'm using the correct terms.... I have a hardware system build around a microcontroller. The mC is programmed in C, no OS. The system accepts commands from interrupted serial port and does "things"... Some of the things it does are fast, relative to the rate at witch the command are coming (the task can be executed between 2 comma

Hello All, I am looking for a concept for abstracting of a hardware. It is desired that the concept should be convenient, clear, consistent, logical and pretty universal. My goal is developing more or less universal HAL and application framework for automotive, control and instrumental. It should not be tied to a particular OS, CPU or board. Can you recommend a good reading on tha...

Hello, I'm looking for JPEG image processors (encoders). I found only 2, ADV202 from Analog Devices and PM-36 from Zoran. I would appreciate if anyone could point me to similar devices. It doesn't need to be very fast. I intend to capture one frame of NTSC video with Philips' SAA7111, and then do the conversion to JPEG in hardware, with a dedicated IC. I only need a few frames per second...

For a demo project we want to use a webserver interface to some simple hardware. The initial demo will be 3 devices and after that a very small annular volume. For that reason we don't want to invest too much in hardware/software development and are searching for an off the shelf product. I thought I would find that in a minute, but so far I have been unsuccessfull. What we would like: - M...

Hi - Can anybody tell me for what, if anything, does GCC use the single-precision hardware floating point units on some Cortex-M4 parts? At all? Single-precision float only? Presumably not double? The PIC32MZ EF series parts have hardware double precision; presumably GCC uses this for double? Thanks! Best Regards, Dave

Hello, Someone here with Zigbee experience could provide me some suggestions on what hardware (modules) to choose? I'm looking for something tiny and easy to use. Im thinking on the TI CC2530ZNP Mini Kit once I found many zigbee modules that are based on the CC2530 chip. The Zigbee Processor (ZNP) seems interesting. However I don't know if it is really out-of-the-box or easy to use. And not...

I have some hardware that has a PIC18F6680 pic cpu. This is older hardware that is non programmable that we are starting to replace with a reprogrammable version. The newer version is the basically the same, but has a maxium max3233e rs232 chip, and a mini headphone jack that we connect to a laptop to program with vendor software via a laptop w/serial port. What would be the easiest way to re...

Hi, I'm exploring tradeoffs in implementation of some computationally expensive routines. The easy (coding) solution is to just use doubles everywhere and *assume* the noise floor is sufficiently far down that the ulp's don't impact the results in any meaningful way. But, that requires either hardware support (FPU) or a library implementation or some "trickery" on my part. Hardware...
