Pseudocode. Transaction Data and Master/Slave Length Mismatches ¶ Normally, the data that needs to be transferred to or from a Device is read or written to a chunk of memory indicated by the rx_buffer and tx_buffer members of the spi_transaction_t structure. If the microcontroller features a built-in hardware SPI, then the display module can be interfaced as a SPI slave device. Creating an easy to implement realization of SPI slave would definitely help the BeagleBone community members to write applications based on SPI much more easily. The SPI bus can support a variety of transfer speeds but the bus is limited by the system´s clock. These drivers are included in the design files with this design example. This file contains a design example using the SPI driver and hardware device with a serial EEPROM device. We do however have a SPIMessageQ module and a WiFi driver that utilize the same SPI driver.
