Example Description
This example describes how to get data from pl7223 by SPI conneciton
The SPI Interface provides a "Serial Peripheral Interface" Master.
Hardware connection:
Connect SPI0_MOSI (PC_2) to PL7223 MOSI
Connect SPI0_MISO (PC_3) to PL7223 MISO
Connect SPI0_SCLK (PC_1) to PL7223 SCLK
Connect GPIOB_5 (PB_5) to PL7223 CS
Connect GPIOB_4 (PB_4) to PL7223 RESET
Connect GROUND together
Connect to LOG UART with configuration 38400 8bits, 1 stopbit, no parity
After boot up, the ameba will reset pl7223 into MCU mode and get data from pl7223.
After Gatherin and calculating, program will show information to UART.
