mbed 1768

Postby olzeke51 » Sat Nov 22, 2014 2:22 am

the stock mbed 1768 that you offered referred to a file system/commands.
Since I don't have the official mbed 1768 (I do have the ArchPro1768) what is the
pins and device used in the mbed-Basic that you offered??
Thanks - Gary

per internet info re: mbed LPC1768
SPI interface is used for SDcard i/o , usually
p5 is 'mosi'
p6 is 'miso'
p7 is 'sck'
??p8 is 'cs' - seems to be programmer defined sometimes
'
Is this what your file commands are programmed for??

MY BAD
the 'p' numbers refer to the physical connection to the mbed carrier board. !!
'
it looks like p0_6 is the 'CS' pin.!? Could you verify that this is the pin YOU use for device select??
_7, _8, _9 are the SPI pins.

Thanks, [in advance]

I updated the help file page to list the SD card connections for both mBed, ArchPRO and SuperPRO

http://www.coridium.us/ARMhelp/index.ht ... gFile.html

I think your counting was off, it doesn't help that the image is flipped from the picture in the Pin Info page, I looked at swapping that image, but it doesn't really help all that much. The list does.

I have not verified the file operations of either the mBed or ArchPro yet.
