Hi Amraldo,
Thanks for your kind reply. I already referred to the documentation when I was trying to port it, there were things that were not included in the documentation, like how to port in my specific compiler. I was bounded to using that compiler because all the rest of my code (low level...
Hi, has anybody worked with the MTK chipset for mobile phones? (chinese manufacturer)
I have heared this chipset is illegal in some countries but don´t know why. Is that true?
Where can I download software toolchain to design software for this chipset? Thx
Hi Amraldo,
I tried to integrate a FAT filesystem but it was too complicated, there were too many problems (I had to port it to PIC18, there was not enough information, then my compiler -CCS- couldn´t compile the libraries, etc...)
Now I am reading the FAT filesystem by myself and I am...
Hi,
I am implementing a system to read files on a FAT16 formatted SD card through a PIC18. However I am stuck because I cannot find the Root Directory. I apply the formulae for calculating the start of the Root Directory, as follows:
Root directory first sector = 0x00 + Number of reserved...
Hi all,
I need a good serial port monitor that can show me the contents of a file in ASCII, like the one shown in the link below
https://www.tavi.co.uk/phobos/fat.html
Does anybody know where I can download such tool?
At the moment I am using the serial port monitor included in the...
The Microchip library looks good, is it for free?
What compiler is it for? Have you worked with it before?
Added after 1 hours 16 minutes:
I have downloaded the files and it looks quite interesting, however I don´t know where to start, how to integrate it with my application and my low level...
Hi,
I am porting the EFSL FAT filesystem to PIC18, apparently it´s done for AVR and ARM but not for PIC, or at least I haven´t been able to find the way to compile it for PIC.
Has anybody done this before? Any help or code would be welcome. I have low level routines for interfacing with an...
Hi Davenjose,
I am trying to implement a FAT filesystem on PIC18 as well, but I´m struggling with it.
Do you have code examples for PIC18 and FAT? How do you compile everything together? What library are u using?
Thanks and best regards
Thanks for the links. I have been looking at them and looking at the selection tables for LPC2000 as well as AT91.
These are the requisites for the application:
- SD/MMC interface support (could be implemented through bit-banging SPI if it was easier or cheaper)
- USB interface. Ideally we...
Spiralbrain, what board are you using? that seems interesting.
What do you guys think about this development board to start with?
**broken link removed**
What would you recommend, AT91SAM7S256 processor or LPC2132?
Hi, I am new to ARM development, I would like to do an example project programming an RTOS into an ARM processor.
Where do I start? I would like to use Linux on ARM if possible, but other open source RTOS would be fine too.
I want to know how it´s done, what tools are used, where to download...
Hi I am interfacing a PIC to an MMC through bit-banging SPI, I think all the signals are correct on my interface according to what I see on the oscilloscope, but the MMC never sends any response back on the MOSI line...
I send the Reset command according to this timing diagram but don´t get any...
I am building an MP3 player with MMC/SD card interface to a PIC18F4550 through SPI, but I cannot get any response from the card, here are the details, anyone can help me?
- When I read from the card, the MISO line is all the time high or "1". I expect to receive an R1 command or "0x01" but I...
