SPI master half duplex EEPROM example
This code demonstrates how to use the SPI master half duplex mode to read/write a AT93C46D
EEPROM (8-bit mode). There is also an Kconfig option EXAMPLE_USE_SPI1_PINS
allowing use the
SPI1 (bus with code Flash connected on official modules).
Connections
For different chip and host used, the connections may be different. Here show a example diagram of hardware connection, you can freely change the GPIO defined in start of main/spi_eeprom_main.c
and change the hardware relatively.
