[Use MTDS with arduino ARM processor]

Hi jpeyron,

Yes in fact it is compiling without error. I try to run one of the script give with the lib (MyDispDemo1) but mydisp.begin(); return all the time false so I am stuck in the first while (line 96).

And the pins are the same between Duo and Uno for this type of shield, so I think that I should good connected.

Thank you

Hi jpeyron,

Thank you for your answer. So I added this code and also in function bool MtdsHalSpiReady()  I copy paste the code for AVR and change the defined with SAM3X8E. Same in function uint8_t MtdsHalPutSpiByte(uint8_t bSnd) .

Now it goes in else if (SAM3X8E), however nothing is declared in the scope. I got this type of error:
 

C:\Program Files (x86)\Arduino\libraries\mtds\MtdsHal.cpp: In function 'void MtdsHalInitSpi(uint32_t, uint32_t)':

C:\Program Files (x86)\Arduino\libraries\mtds\MtdsHal.cpp:339:2: error: 'SPCR' was not declared in this scope

Do you have an idea, how to declared those things ?

Thank you

 

[Use MTDS with arduino ARM processor]

Hi everyone,

I just bought a MTDS (https://reference.digilentinc.com/reference/add-ons/mtdshield/start)

I tried to use on an arduino Duo (arm cortex M3) and I got this error :

C:\Program Files (x86)\Arduino\libraries\mtds\MtdsHal.cpp:326:2: error: #error "No supported processor defined"

 #error "No supported processor defined"

So I have checked MtdsHal.cpp at line 326 and I saw that the SPI is set for PIC or AVR processor.

Is there a solution for arm processor ?

Thanks
