DP32 & any built in SD example produces compiler error

Using a Chipkit DP32 board, when I compile any built in SD examples, they all produce a compiler error. Tested on both MPIDE 2130626 and the latest MPIDE 20131118.

I then included the mapPps function, but it made no difference.

The SD library is pure evil.

Everything in it is, rather stupidly, hard coded, and it hasn't got anything in there for the DP32.

I have a modified version of the library that uses proper SPI interfacing and the real DSPI device than I have bundled with the chipKIT core of UECIDE. It should work with any hardware SPI device, or any other pins through internal emulated software SPI (using shiftIn / shiftOut).

I'll attach it to this post, but I can't guarantee it'll work in MPIDE - note, you have to modify any sketches to include the DSPI.h library.

Thank you very much majenko, I'll will give it a try. Thanks.

Same issue, trying to set up HW config instead of the default sw spi for a fubarino.

See that you set mega_soft_spi to 0.

Where are you setting the mosi,miso, CD and clk pins ( fubarino has clk on 24, mosi on 25, miso on 26 and CD on 27)

Straight SPI works for me on the DP32 defined as follows:

#define chipBUS_an 11 #define chipBUS_rst 12 #define chipBUS_cs 9 #define chipBUS_sck 7 #define chipBUS_miso 10 #define chipBUS_mosi 18 #define chipBUS_pwm 13 #define chipBUS_rx 6 #define chipBUS_tx 4 #define chipBUS_scl 2 #define chipBUS_sda 3 // #include <LCD5110_Basic.h>

LCD5110 GLCD ( chipBUS_sck, chipBUS_mosi, chipBUS_an, chipBUS_rst, chipBUS_cs );

That is to drive a display but should work fine for any other SPI device.
