Hi,Does anybody know where I can find necessary parts to start working onHC12? I'm looking for HC12 itself, its programmer and anything which isnecessary to implement a project using M68HC12.Thanks,
Anyone have Ethernet running on Mot HC12? Comments on both commercial andfreeware and appreciated.Thanks,David Evennou

Hi!I am trying to implement a software real-time clock on the HC12 usingthe timer module. I am pretty much unable to do it at this point andwas hoping that someone could point me in the right direction --perhaps even coded examples that could serve as a way to betterunderstand it. I need to keep track of a 24 hour day, no need for anyactual dates. I can code using either assembler or...

Hi all,I am planning to develop an embedded application with theFreescale (Motorola) MC9S12DP256 microcontroller.I aleready have a good 10 year knowledge of HC11/HC12C/assembly programming, and electronics design,what I need now is a good development kit,including compiler and Backgroud Debug Mode.Question # 1So what kit should I buy to start with ?I saw IAR Embedded Workbenc...

Hi all,I'll develop an embedded system based on FreeScaleHC12, mainly using MC9S12NE64 and MC9S12DP256.In short, MC9S12NE64 - based will be a card collectinganalog sensor's data, an ADC, an Ethernet port, whilethe MC9S12DP256 - based will be a more versatile oneto develop prototype for some other future projects.I am currently looking for a development kit :SofTec inDart-HCS12...

HI,I am implementing an ALP program to implement a real time clock to displayhour,minute,second using features available in a timer unit. Digits have todisplayed on one of the GPIO ports of HC12 micro-controller. I do know how to proceed on this in C language but am a newbie inmicro-controllers and assembly programming - was hoping that someone couldpoint me in the right direction -- p...

When I connect a target board to an HC12 EVB and use Metrowerks v2.0freeware IDE, I can assemble, link, go to the debugger and downloadinto RAM. When I set my default.prm file for the linker to point toflash, the download fails with the message:Elf-LoaderError while writing to 8000..80B4Looking at the communications between the debugger and the EVB board,I see that when I load RA...

Ok, flamewar time I guess.I am looking to explore new microcontrollers because the ones I haveunder my belt are coming up short for what I need. I have a lot ofexperience with the 16 series of PICs from Microchip, I have playedwith basic Stamps (I, II, SX), some experience with Motorola's HC11,HC12 and HC16 series. Currently I use Atmel's AVR (Atmega128) at work. But in trying to b...

Hello from Milan ,Italy,i'm programming a 9s12 uC in C language,with occasional assembly inserts;the question is:a function myfunc() is runnin,and an external events calls an interruptservice routine,is it possible,once the interrupt did its job,to avoid tocontinue with my func()from the point where it was interruptd,and going back to main() instead?Itis not important if i have t...

Hello,I have limited experience with microcontrollers, all with freescale HC12and HCS12 systems. I have dealt with 0-5V sensors through ADC before, too.I currently have a project where I might have to use a 4-20mA sensor. Howwould I go about electrically interfacing a 4-20mA sensor to a genericmicrocontroller? How would you power it and read it? Is there an ICavailable?Any suggest...

Hello, I had a few real basic question about microcontrollers. I'vebeen learning the motorola HC12 at school, but whenever I pick upmagazines or any kind of hobby related embedded type of readingmaterial, the microcontrollers I see most often mentioned are the PICand the STAMP and now something by Parallax called the Propeller chip.Here's what I'm wondering: Are the HCS12 more powerf...

Hello.I'm writing a program for an NE64 board, which reads a series of dataover the SCI1 port, and then transmits them over the Ethernet port.Pretty much it's done and works, but due to the amount of datacollected on every reading, I have to send out 10-15 packets everytime.My problem is that, when the function for UDP transmission isexecuted, some of the data received on the serial ...

Hello,I am relatively new to the 68HC12 (about 5 months) and I'm using it inaproject that I've been working on. I know that the 68HC12 has anexternaladdressing scheme that will allow one to reach 1MBytes worth of data.Myquestion is this:What types of external memories are available? I have found an I2C1MbitEEPROM and some SPI flash memories, but nothing near 1MBytes that I...

Hi all,I'm currently using a HC912 EVB board to transmit the data convertedfrom ADC to SCI and then transmit to the PC, hoping PC will get thedata and display. But it seems nothing is received on PC, although theD-bug 12 is shown in Hyperterminal, while the program is executed,only thing I can see is User breakpoint encountered, and none of thedata is received. I tried MS kermit al...

Hi,I am new the website but I've taken a microprocessor class before and usedthe HC12 board so I know the basics of embedded design. For my seniorproject we are suppose to design a pill dispenser that receives scheduleinformation from a website and dispenses the specific pill accordingly tothe time of the schedule. Now I guess my question would be what kind ofmicro-controller would I need...
