Hi, I am hardening up on using Code Red 4 for my new STM32L15xx based project and I wondered if anyone here can tell me from experience whether they have had any issues or problems with this tool set ? From what I've seen so far it seems OK and they've been quitre responsive by email. Price is good so all I need is the gotcha list to make a decision :-) Thanks, Mike

Hello, Could someone point me to something that could help me creating/understanding GUI for embedded systems in general? What's the "easier" (I know "easy" could be relative) to get GUI on an embedded system? The hardware I'm looking for is ARM-based microcontrollers (Cortex M3, ARM7 or ARM9). I think Qt could be a solution right? However I would like to know "lighter" alternatives. T...

Sorrry for the delayed reply.. Using the 3M part. Will have at least 512M. In the interim I happened across this post on Keil's website. http://www.keil.com/forum/13316/ It basically says that because Actel has not implemented 'OS extensions' that no OS will run on this core. I also found that Actel has ported a v3, which does support OS extensions, to their SmartFusion line. --which ...

I have been watching Luminary the last couple of months and I am impressed with how they have brought out a number of chips using the new Cortex M3 ARM core. The chips have some nice features, such as executing at the full 50 MHz from flash and being available in the small 48 pin QFP. They offer up to 64 KB of Flash which is the most in a leaded package this small. On the down side, they...

Is there an SQL implementation that works well on lower end embedded projects? ARM7/Cortex type devices are primary what I am looking at. These chips can barely run a version of uCLinux, so SQLite isn't exactly an options. Was curious what, if any options are available for something like this. I am guessing most implementations will require too much memory to be of use here. ...

I made some projects using some ATM91SAM7 devices (S256 and now obsolete A3) and now I need something speedier/bigger to let this design grow. The best solution is to go with the ATSAM3 family (I already have an ATSAM3U EVK), speedier/better core with the same great peripherals I know. BUT Even if Atmel presented the ATSAM3U more than one year ago it still missing from the distributi...

Hi I am not an embedded expert, so please be patient I have an application with 6 phase PWM and the CC2650 TI processor does not have deadtime support (to avoid cross conduction in a 3 stage halfbridge design) So, I could code this so when the timer PWM compare capture is updated, I check the value that is needed to setup and adjust both the lowside and highside compare values

I'm looking for a Cortex-A class processor that has reasonably quick parallel I/O that might be hooked up to an FPGA. I'm aware of the existing Zynq and Altera SoC FPGAs, but looking for something different. By 'parallel I/O' I mean ideally a memory interface - either bidirectional eg 64-bits or separate 32-bit tx and 32-bit rx. GPIO with data valid signals/strobes is another possibility....

I am having problem jtag an ARM Cortex M3 at more than 1/256 of the system clock (6Mz). If I clock it any faster, the chip reports data overrun error. Is there any solution to speed it up? I can jtag an AVR at full speed, so I don't think it's a jtag problem.

Hi everyone! This is my first post here :) I'm interested in making a platform which has an 32-bit MCU as the central component.

From what I've read on the internet is that NXP has pin- & software-compatible devices in Co...

Hi everyone, Now, I'm quite new in this, so please forgive me if I say silly things. I'm seeing whether or not it is possible (feasible) to implement MLC NAND error correction coding on our current system. We have a cortex-M3 (1MB Flash, 128K RAM) and a small FPGA with no DSP. On the FPGA I only have ~1K LUTs remaining. After searching the internet I found that BCH most commonly men...
