Component macro

filesd::initialise()

Don't step out on real hardware running.
Work flow
1.-Initialise screen
2 - initialise sd module
3- print: finish line code

Hello,

Please can you attach your project file.

Are you using an AVR based micro by any chance? The hardware spi can lock up on these if the ss pin is left floating or allowed to go low. It will need to be set to an output or tied to VCC with a pull up. If you can use it as your CS pin then that should solve the problem. Its a feature of AVR hardware.

Of course if you're not using an AVR then it's something else.

Do you have an Sd card in the card holder? It won't initialise with out it present

With no card present you should get a return of 255 but it shouldn't cause a lockup in the init macro.

Spi cs/ss is working well and correctly conected

Initialise sd macro can't step out to continue the flow.
In the example:
1.- an output begins with 0
2.-then the component macro "sd initialise"
3.-and at the end output change to 1 to turn on a led
The led don't turn on, the initialise sd macro can't step out.

If disable sd initialise macro Led turns on so looks like sd macro initialise can't step out to work with sd module

Hello,

Please change the CS pin of the SD component to pin D10 / PORTB.2, this should solve the problem.

Please see my first post for an explaination.

---> The CS pin of the SD component to pin D10 / PORTB.2 DON´T FIX THE PROBLEM
--> DEFAULT CLK PIN SETTINGS (CHANNEL 1) PORTB.5 DONT WORKS

THE PROBLEM WAS SOLVED IF:
CHANGE CLK PIN PORTB.5 ----> PORTB.0
