Whenever you need to process signals, be it audio/image/video or other signals in real-time you need a DSP for that, especially if you're doing on an OS hosted platform where you can use DSP like a peripheral device. BeagleBoard xM is one example where it has a C6700 (I guess?) DSP as a...
If you're using your own SPI routines then you should be good to use dhrmanitech's FAT32 code, download the example and use it.
I used it in the past and got it working on PIC and AVR both. 8051 shouldn't therefore be a big deal. You just need to change some register names and values and...
For all string transmissions if you have const char* input i.e. input like "Hello World" instead of pointer use pointer type cast to resolve the issue, for e.g.
LCD_Out_Cp((unsigned char*)"Hello World!");
I see that your Line 17 is wrong, you need to pass a pointer to LCD_Out_Cp and hence only...
MAC and FMAC instructions are peculiar to DSPs. A DSP has a very high Integer/Floating-Point calculation throughput compared to a normal CPU, so DSP is basically processor specializing at doing calculations on Integers, floats, doubles and vectors of these types i.e. it can perform add/multiply...
You could try capacitor voltage transformer and then use the very popular 7805 series voltage regulator or any other DC-DC voltage regulator.
If you need a high efficiency then DC-DC Buck converter is what you need
I have a lightweight and running code for SD Card r/w using SPI with FAT32 but that's on ATmega. You can modify registers and vavlues in SPI related functions or you could provide your own SPI read/write byte function to the code...
A little elaboration is required, what is it that's required at-least the frequencies that you need to carry out that task.
horace1 suggested the right thing to do which is helpful most of the times. Use any CCP interrupt to get that done. You could use 3 different timers with different...
