|
|
|
* Allocate a DMA channel. This function gives the caller mutually

* exclusive access to the DMA channel specified by the 'chan' argument.
|
|
|
|
* DMA channels are shared on the STM32: Devices sharing the same DMA

* stm32_dma.h.
|
|
|
|
*
|
|
|
|
* If the DMA channel is not available, then stm32_dmachannel() will wait

|
|
|
|
* stm32_dmafree(). WARNING: If you have two devices sharing a DMA

|
|
|
* The external functions, stm32_spi1/2/3select and stm32_spi1/2/3status must be

|

|
* include/nuttx/spi.h). All other methods (including up_spiinitialize())
|

|
|
* are provided by common STM32 logic. To use this common SPI logic on your

|
* board:
|
2009-09-25 14:17:18 +00:00
|
|
|
*
|
|
|
|
* 1. Provide logic in stm32_boardinitialize() to configure SPI chip select
|
|
|
|
* pins.
|
2009-10-15 23:16:14 +00:00
|
|
|
* 2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() functions in your
|
2009-09-25 14:17:18 +00:00
|
|
|
* board-specific logic. These functions will perform chip selection and
|
|
|
|
* status operations using GPIOs in the way your board is configured.
|
|
|
|
* 3. Add a calls to up_spiinitialize() in your low level application
|
|
|
|
* initialization logic
|
|
|
|
* 4. The handle returned by up_spiinitialize() may then be used to bind the
|
|
|
|
* SPI driver to higher level logic (e.g., calling
|
|
|
|
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
|
|
|
* the SPI MMC/SD driver).
