Kieran, Is this also true of the 68hc11f1, 68hc11k0, 68hc812a4? We have become frantic here after seeing the 'not recommended for new design' message on all...

Salvador, Is svc_malloc declared with a function prototype before you use it? The problems you describe could be caused by a type mismatch caused by an...

Steve, Thanks for the answer. Yes I have correct prototypes for everything. it is very weird what I saw. I remember that sometime ago I was getting an error...
Hi all, I've been working with the 9S12E128 MCU and have found an interesting problem when using metrowerks code warrior. On my program execution, an illegal...
Just recently I ran into a similar problem in the same part of start12.c code. The problem appeared when I started tinkering with compiler optimization...
Yes that also works ... there is an optimize for size setting in the same code area ... depending on what you have selected drops in different copy down code. ...
My employer is using M68HC705B16 which was obsolete 10 years ago. It was only a few months ago that we had a hard time buying this because it's no longer...
Actually this has been fixed in the start12.c contained in the HCS12X V4.0 release (which does not target HC12/HCS12 directly, but the start12.c it contains...
Hi All Each port has a register for enabling a pull up or down device. I was just wondering if that is just two internal resistors? Enabling one or the...

Hello, I can't get the SCI1 on my E128 EVBU working. I can't read characters or send characters using it. I have set the reciever enable and transmit enable...
Abliviax, If you have the board's schematic, you can save a lot of time by reading it, even if you have no other documentation on the board. I wouldn't work...

Hi everybody. I designed a board with a MC9S12A256C that's running at 10MHz of internal bus (xtal=3.579Mhz) and i write in flash a lot. The thing is that the...
Are you sure you did not secure the device.. What do you mean by "i write in flash a lot"? ... [Non-text portions of this message have been removed]...

You can look at the help as it was suggested already, I also suggest you use type definitions for different data sizes that represent the exact number of bits...
According to some people from Freescale we talked to yesterday, that NOT RECOMMENDED FOR NEW DESIGN notice got put on a lot of parts across several MCU...

The benefit I mostly get is this: I am now developing common code for both x86 (Pentium) and HCS12. The source files therefore have the same U8, U16, U32 etc,...
I just recalled another advantage as soon as I went back to work, here it goes: I normaly do all my automated unit testing on the PC regardless of what the...
I am trying to build small "services" that are loaded in pages of a DP256 device. The services are actually tasks in a multitasking environment. While I am...
Thanks for the reply, Sal. Good explanation.. I can see an advantage for 'multiple platforms'. My experience has been that not much source can be used between...
Changing code is not as painfull as it seems. In my begining years, I used to use different names for these variables, like byte, word, dword, etc. Then when I...
By the way, I also planned for big/little endian since I obvioulsy am working in both worlds. In this case is simple, I isolate those processor dependencies in...
Hi everybody I've bought a miniDragon board from Wytek and been trying to run the IIC block. But I'm lost in the Motorola documents. All I would like to have...
Hi, When you say you write to the flash often, can you calcuate how often you did write to the flash? Has it exceeded the max number of permissible write...
Hi all, I want to programm a delay function in c, which can delay the hc12 xx seconds: void delay (int seconds) { ...; } Are there ready tested delay...
Hi, do you really want to program a delay with a simple loop, which the processor "stops"? If you program a loop like you wrote below, you can't make anything...
