When I create full length name "FILENAME.TXT" it resets the chip (pic24) and does not create anything.
Once I remove one symbol and create "FILENAME.TX" or "FILENAMETXT" - it's ok.

Also interested in some tips and tricks in FC.

any updates?

It's on hardware. upd: seems like something is wrong with switching at SetFileIndex. Even when I set wrong index (file1 is 0 and file2 is 1, but i set to 2) it was reading and writting from/to the last opened file. Same confirmed when I've changed the order - opened file2 and then file1. It was read...

same. here's the file2.txt result after the cycle

I am trying to read string from file1 and save it to file2 using SetFileIndex(0) and (1)
But I get read strings from File2 and added to same File2 at the end.

What may be wrong?
Code screenshot included.

any updates? still waiting for the solution

I see that the code is simple, according to the example from microchip. But C is not my "native" language and I have troubles with correct injecting this code into Flowcode project. That's why I am asking for help. If you tell me that it will be done, I can wait for a week, of course.

Benj, check pm

up. still actual. no one can do this? unbelievable

still looking for someone who can create two macros to read and write to program memory of pic24. I need to store 300 bytes of data (settings and so on). So macro must read and write byte by byte or by whole block (so I could read 300 bytes buffer, modify and write back). Can pay some money for the ...

Reviewed the code. but C is not my "native" language, so I will need help anyway.

still looking for someone who can create two macros to write and read from pic24 flash memory. I am ready to pay some money for the work time, if necessary.

your example seems to be for external memory with i2c interface, doesn't it?

still looking for someone to help me with writting to flash. as a result i need two macros read and write from and to flash. data to store: several variables (50-100 bytes of data). maybe someone can offer payable support?

Found documentation about EEPROM emulating in PIC24.

Who can help me to integrate that example into FC project correctly? We can chat over icq or skype.

Understand now. So this way I can modify any sector of opened file? If I have 10 sectors, I can move 5 times to next sector, read and write it, and then move to the end and continue adding new sectors, right?

Thanks, Benj.
So when I do OpenFile it sets the marker to first sector. And how do I continue writting sectors after the last one?
For example, I've wrote 2048 bytes of data (4 sectors), then I do OpenFile to modify 1st sector. Then what should I do to continue writting sectors (5th, 6th...) ?

Hi,

If I continuously write data into file and then need to modify first two bytes of this file and then continue to append the data , how can I do this in FC?

Rudi, finally, did you get the working code?

Are there any way to write my data to flash program memory on PIC24? It does not have EEPROM so I want to use free flash space. Can this be done via FC or should I implement C/ASM code?

Understand, thanks. So for now I better use GetByte and get average value manually accumulating several values, right? Can you advice me some method when I can get sound signal from analog input at 22-44khz frequency? When I use GetByte or RawSampleByte I can't get them so fast with interrupt set to...

Benj, what's the problem with GetAverageByte?
When I use this function the whole chip is freezing.
Simple project is below.

yeah, seems like FC is more friendly to atmel rather than to microchip..

What is the exact chip? Do you have the source of the other firmware? pic24fj64ga002 No I don't have source for other firmware. So you could reduce the 40 to something like 1. (Do not use 0) Yes, during playing with settings I did reduce to 1 and even to 0, it worked but again I could not raise int...
