[Paparazzi-devel] SPI with 16bit on LPC2148(YAPA)

[Mauro Garcia Acero]

Dear all,

 

The spi.h from mcu_periph is referred to transactions of 8bits words. For example:

extern uint8_t* spi_buffer_input;

 

The same for spi_arch.h from ../lpc21/mcu_periph/, but I have read that the LPC2148 can deal with 8 to 16 bits per transfer.

 

As long as I see in other modules, read registers from SPI devices are made as follows:

 

  spi_buffer_input = (uint8_t*) ....;

  spi_buffer_output = (uint8_t*) ....;

  SpiSetCPHA();

  SpiStart();

 

I don't thing that spliting every command into 2 bytes and sending them independently would work.

 

Any ideas?

 

Best regards,
Mauro.
