sdio_slave_recv_register_buf() function
Register buffer used for receiving. All buffers should be registered before used, and then can be used (again) in the driver by the handle returned.
Syntax
Implemented in ![]()
sdio_slave.c:759
Return value
The buffer handle if success, otherwise NULL.
Notes
The driver will use and only use the amount of space specified in the `recv_buffer_size` member set in the `sdio_slave_config_t`. All buffers should be larger than that. The buffer is used by the DMA, so it should be DMA capable and 32-bit aligned.
