Problem with DSPI Library on certain Boards

In testing my Boards Definition files I get the following error when compiling the Sketch: PmodJstkDspi

DSPI.cpp: In constructor 'DSPI0::DSPI0()': DSPI.cpp:839:21: error: '_SPI2_BASE_ADDRESS0' was not declared in this scope DSPI.cpp:839:21: error: expected ';' before 'anss'

I get the same error if I select ChipKIT DP32 as the Board.

On the Fubarino Mini I get:(after fixing the PIN_LED1 error)

DSPI.cpp:917:1: error: 'DSPI1' does not name a type DSPI.cpp:946:1: error: 'DSPI1' has not been declared DSPI.cpp: In function 'void enableInterruptTransfer()': DSPI.cpp:948:11: error: invalid use of 'this' in non-member function DSPI.cpp:949:32: error: cannot call member function 'void DSPI::enableInterruptTransfer()' without object DSPI.cpp: At global scope: DSPI.cpp:969:1: error: 'DSPI1' has not been declared DSPI.cpp: In function 'void disableInterruptTransfer()': DSPI.cpp:972:33: error: cannot call member function 'void DSPI::disableInterruptTransfer()' without object

The Example compiles Cleanly on an Uno32

Would it be related to PPS mapping? I will try that and see if it resolves it. ON

adding the following results in the same errors as above:

mapPps(11, PPS_OUT_SDO2);
  mapPps( 7, PPS_IN_SDI2);
  mapPps( 8, PPS_IN_SS2);
  pinMode(11, OUTPUT);
  pinMode(7,  INPUT );
  pinMode(8,  INPUT );

Hello Chris,

There are a couple things. One, there is a typo in the Board_Defs.h file for the DP32. The 'anss' should be deleted. What was the first board you were using? Regarding the Fubarino Mini, looks like the Board_Defs.h file defines NUM_DSPI_PORTS as 1, but it has definitions for DSPI1 and DSPI0.

Best Regards,

Thanks Jordan,

Removing "0 anss" from all files worked. Both the DP32 and My own Files now compile clean.

The first Board is not really a Board at all, it is a PIC32MX250F128B on a Breadboard.

I am busy developing a couple of Bootloaders for the MX150 and MX250 device that will allow for rapid prototyping and field upgradability. I am developing a Boards Entry to go with them such that the parts become interchangeable. If you don't need USB but need more I/O, pop out the MX250 and drop in an MX150, your Sketch should run unaltered.

I have been using the DP32 and Fubarino Mini Board Definitions as prototypes as they use the MX250.

Cheers, Chris
