Please help, 2 different SPI libraries not getting along with one another....

[themindfactory]

I had to use 2 different SPI libraries because the SD class needs SPIClass and my WS2812 controller needed another so it could support the continuos sending of data with no breaks, it did this by ways of DMA, DMA was not required by me, but this is how it did it....

If I could make SPI Class send a continuous stream of bits over SPI then I could use one, but I can not, have tried.... there is always a time gap from one transmission to the next.

I have attached 2 files that support the DMA continous stream....

I would get error messages that said spiwp pin not defined... which is very odd, then it would crash and reset, it would give this message when it was executing this... E (7793) spi: spicommon_bus_initialize_io(146): spiwp pin required.

mySPI.begin(MOSI_PIN, MISO_PIN, SCLK_PIN, 12 * nLEDS);
mySPI.addDevice(SPI_MODE, SPI_CLOCK, CS_PIN, &spiDevice);

it would happen during the .addDevice phase....

I am using the new 1.0.0 version with Arduino 1.8.5
