Example Description This example describes how to communicate with AmebaZ gspi interface. How to build: 1. copy src\main.c to project\realtek_amebaz_va0_example\src This example source code(mian.c) contain both GSPI slave code and SPI master code, you can use "CONFIG_GPSI_SLAVE" to choose which dirver to run. "#define CONFIG_GPSI_SLAVE 1" for GSPI Slave "#define CONFIG_GPSI_SLAVE 0" for SPI master Requirement Components: 2 AmebaZ Board AmebaZ (A): Assign as SPI master SPI0_MOSI : PA_23 SPI0_MISO : PA_22 SPI0_SCLK : PA_18 GPIO_CS : PA_28 GPIO_INT : PA_27 AmebaZ (B): Assign as GSPI slave GSPI_MOSI : PA_20 GSPI_MISO : PA_22 GSPI_CLK : PA_21 GSPI_CS : PA_19 GSPI_INT : PA_23 Setup:connect A and B as given A: B: SPI0_SCLK --- GSPI_CLK GPIO_CS --- GSPI_CS SPI0_MOSI --- GSPI_MOSI SPI0_MISO --- GSPI_MISO GPIO_INT --- GSPI_INT V3.3 --- V3.3 GND --- GND Behavior: A send 2048 bytes to B about every 500ms and B will send whatever received back to A. Every time if A Checks Rx Datas are the same as Tx Datas,then it logs "Succeed" ,else it logs "Failed" and finished.
