Sir,
I am trying to model my design for software defined radio as FM receiver but somehow I am stuck in the final stage, unable to recover signal in the PLL section. I am attaching the model please help me out in completing it.
Here is the link to Simulink Model... **broken link removed**

Hello,
I am trying to make a timer interrupt routine, which executes every 0.25us. The problem I am facing is that, the code length in the routine changes the duration. For example running an instruction at 72MHz, the next time the routine execute is 0.35us. It seems the the timer starts...
Sir Thank you so much for sharing with me your ideas! :)
Your idea is very good, but I need an innovative one.
My group members suggest me to make an industrial standard type Arduino but it still lacks automation, control and application. I am very much interested in Control Systems application...
Dear members,
Now I am a final year student, in Institute of Industrial Electronics Engineering. Our main specialization in this field is automation.
I am a little bit experienced in embedded systems. And I have done various projects on AVR and PIC microcontrollers. We have also studied PLCs in...
FvM,
One last thing I want to ask you that I am able to read write only after I finished my controller programming, It also works when I do not power off just reset the controller, but after powering it off. After applying power again the card is again undetected. During this power off and on, I...
I am now cent % sure that it is not an issue of hardware, but of my software. The software is detecting MMC but I can't simulate an SD card on proteus and the main issue is in the code for SD version.
As I know, there are three different approaches to detect memory cards.
Can you please provide...
Hi FvM,
The problem remains the same.
I think the card I am testing in simulation is an image file of MMC, but the card I am testing in hardware is an SD Card, I have triple checked all of my connection and they are giving outputs as wished.
I am sending you my edited program which is able to...
The Circuit is just meant for hardware...., also I have tried at all of the spi clock prescalars, even increased the no. of retries to detect it.

Hi Dora,
I am able to detect and even write it using proteus...
Hi, everyone,
I have learnt alot about SD card interfacing and i am able to save and extract data from an SD card(in simulation).
After several attempts I am also able to run it in hardware environment, but my issue is just not simple because although it runs on hardware now, it detects SD card...
The problem is resolved now, I am now able to write and read the MMC card.
Do you know any hack for which I can test an SD card on Proteus ISIS, instead of a MMC card?
And do you wan't to give me any suggestion regarding fat16 file system implementation on SD card?
