Hi, thought this might be interesting for those that are using ARM in MCU related applications. They are continuing to upgrade their cores and making it more difficult to not use ARM :-) Saw it here while browsing. http://mcu-related.com/ An Schwob

Any time I ask a really specific question here it always seems to go by the wayside. But what the heck -- it's Friday, it's late, and my @#$% processor won't go to sleep!!! Anyone have any mileage with the ST Arm Cortex parts and sleep mode? I've got a STM32F303 that doesn't really need it that goes to sleep beautifully, and I've got an STM32F051 in an application where low power is...

Hi guys I am trying to interface the enc28j60 ethernet controller with one of the Atmel cortex microcontroller and my development environment is IAR embedded workbench. what I am trying is that I am trying to get the ip address assigned to my controller with the dhcp module. Actually the whole network is laid down as follows: I have one D-Link router of series 600M and through this ...

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

Hi So, I have been using a ST Cortex M0 STM32, NXP LPC, PIC32 and also a Renesas RX63. Just for fun. They look interesting as a potential candidate All processors has a bit to set it up in protected mode, so the flash with proprietary IP cannot be read out But, say my competitor wants to dig into my code Is there really such a thing as a safe micro controller which memory is protecte...

I have bought few Blue Pills on Aliexpress. I expected to receive boards with some of known clones. But what I get does not look like any clone that I have heard of: - Cortex M4 with no FPU - 32k RAM - 128k flash - set of devices like STM32F103C8T6 Chip seems to be resonable compatible, but I noticed notable difference in I2C peripherial: bit 14 in OAR1 (own address register 1) se...

Hello All, the Infineon ARM Cortex derivatives (XMC4000 CM4, XMC1000 CM0) look very interesting. Advanced peripherals, good value for the money. Is anybody actually working with them and wants to tell something about what to observe? TIA, Oliver -- Oliver Betz, Munich despammed.com is broken, use Reply-To:

I believe that this group could be interested in the Embedded C Programming Course on YouTube, which I just started to teach (my New Year's resolution for 2013). The playlist for this course is available at: http://www.youtube.com/playlist?list=PLPW8O6W-1chwyTzI3BHwBLbGQoPFxPAPM. The course is intended for beginners and is structured as a series of short, focused, hands-on less

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...

both free samples and 49$ starterkit available, my should be airborn right now somewhere between Paris and my place. The CPLD is small, 190MC, but it still much more then the 16MC availabel in ADI's ADuCs or ST's uPSD devices. PSoC 5, Cortex based devices will probably only be available next year Antti

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 know it's a very specific question, so I don't have many hopes to find a solution here, but I already tried everything and I don't know how to solve the issue I have that is very annoying. I have three PCBs: PCB1 that mounts LPC54101 (M4), PCB2 that mounts LPC54606 (M4), PCB3 that mounts LPC54618 (M4). All these MCUs are from NXP. After I receive the first prototype for each board, I...

Looks like ARM has not moved to double-precision yet with M7. ST announced M7 parts that look really impressive except for this issue, and claims to have preview parts available. Wonder why still single precision?? Hmmm...

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.
