STM34F4 LIS3DSH Accelerometer Code

You're still doing this with the F4? Do you ever call SPI1.setup(...)? I didn't see that in the code you posted above - I guess it's possible that the default pins for SPI have changed for some reason.

Maybe you could try software SPI just to narrow it down:

var spi = new SPI();
spi.setup({miso: yourpin, mosi:yourpin, sck:yourpin});
...
var d = spi.send(...);
