Hello, ... it will be open, Kevin Ross' compatible pod. It is done since July, but the time is problem (of all of us, I think ;). I will tell you. Bye, MP...
... I was under the impression all you need to do is download the two .zips from Freescale and modify a target board or EVB to add BDM output cable and...
Hi, I've a problem with processor security against reading the content of FLASH/EEPROM by unauthorised persons. I've read the documentations and application...
Dariusz, You didn't mention what mask-set of the MC9S12DG128 you are using. For security, I would advise against using the earlier mask sets - 0L85D or 1L85D....

... Hmm, strange... The BDM programmer can be flashed to act like a D-Bug12 pod, but somehow I've been under the impression that it isn't so easy to make your...
The 9S12 family has two separate mechanisms: 1) Protection - prevent accidental changes of content FLASH or EEPROM. and 2) Security - security feature...
Hi, Unfortunately, we have got the 0L85D mask-set. probably a 10k chips. Sit and cry :-( Ok,"Un-secure" It's some solution on today. But, When I'll un-secure...
It would be hard if you had no development setup already. The thing you would be missing in order to make a POD with D-Bug12 from scratch is a way to load a...
Hi all, I finally decided to come here and ask a question that I have been fighting for a while, how to perform a SINAD calculation on a block of already taken...
Hi all, Iam working with cpu12 to make a digital thermometer interfacing it with MAX7221. I have done the code connecting the sensor LM34 it was not giving a...
Mark, I think in your specific case it would be a good idea to use FFT (Fast Fourier Transform), rather than FIR or IIR. In FIR and IIR you perform the math...

Doron, Thanks for the idea! I have a bit of experience with FFTs, but mostly on the PC-side and floating point. I will need to dig up some info on the integer...
... Radix-2 FFT needs about twice as many adds/subs as muls. However, there is a version that needs less muls and adds/subs as well. It is called Winograd FFT,...

Ok, a simple implementation of the Winograd FFT for 504 points must be a closely guarded secret or something. I am not having ANY luck finding something...
Mark, The 180 degree shift you're doing is a good idea. It's called a comb filter. Since you know the phase of the received signal, you can multiply the input...

Since he knows the frequency of his tone, and he knows his sample rate, he can delay his sampled signal by exactly 180 degrees (not 90) and subtract to exactly...
A comb filter could eliminate the S component but the D component too and he is trying to measure Noise + Distortion to get SINAD. Multipliying a signal by a...
Yeah, you hit on the problem, I was removing the distortion as well as the tone, giving me bad results since those additional bandstop filters in a comb lowers...
... Jordi, Oh, doggone it. You're right. I had RF phase noise measurements on the brain; there's a technique one can use for that similar to what I...
