Oh I already solved it the other day, sorry for making you waste your time with your answer asmallri hahaha I hope you didn't have anything better to do, because the question I asked was quite long an ...

I know I know, that is why I asked you if I have to change to 400000

The thing is, I have read before that the proper way to do the initialization was by slowing down the baudrate -so exactly the ...

Thank you, so I will set mode 0.

Some questions about what you just said in your last comment.

The mmc_init code will loop clocking for ever, if mmc_go_idle_state returns 1.

I though we expe ...

Thanks for your answers, but besides there may exist a problem with the SD card, I think I'm programming something badly.

It is the first time I work with mmcsd, but as I read, the pic regardless o ...

I tested both codes with a 2Gb and a 8Gb

Hi, yes there are 4 pull up resistors, one in each line.

The first configuration is basically the codes given CCS. That is:

ex_fat.c
fat.c
mmcsd.c

I tested to write/read a file, and it did ...

Hi!

I'm having problems to set properly the configuration of the SPI port to communicate with a SD card. I have read lot's of post in this forum about the topic, and I tried several of the recommen ...

But Ttelmah, that is for another interrupt, that one is to detect if the buttons have been pressed (and which one).

But below that I wrote the UART interruption, and it is as short as possible.

Hi,

Well I was reading several posts, trying the solutions they give and changing my code. But I still can't solve something as easy as triggering the INT_RDA several times.

The program goes in ...

Thank you very much to all of you for your effort and recommendations. I will follow all of them and test them before posting a new version of my code.

But I would like to add something else I foun ...

Hello Gabriel,

I think I just understood why you mean with printing outside of the ISR.

Do you mean, in the if clause, make a call to another method, for example DoPrint(). And in DoPrint() make ...

Hello Gabriel,

Uhm I'm not sure how else can I print the information. I read for the UART the easiest way is using a stream.

And yes, as you said I was planning to add a Bluetooth module here, b ...

Hello,

I'm trying to send and receive data using the UART of my PIC16F877, through the pins RC7 and RC6. To do so I designed a circuit, where the user can press 3 different buttons, generating a di ...
