1.Question:What are the differences between 8-bit and 16 bit interface operations?
Answer:The difference between 8-bit and 16 bit interface operations is that when sending data (565 data mode), 8-bit needs to send data twice, while 16 bit only needs to send data once.The code is as follows:
1.Question:What is the difference between 3-wire SPI and 4-wire SPI?
Answer:The 4-wire SPI has more RS signals than the 3-wire SPI, which are used to identify instructions or parameters / data. The 4-wire SPI data is 8 bits, the 3-wire SPI data is 9 bits, and the start bit is used to act as the “RS” signal. The start bit = 0, which sends instructions. The start bit is 1, which sends parameters / data。The timing is as follows:
3w SPI Transfer data:
4w SPI Transfer data:
