[ Infineon PSOC 62S4 PIONEER KIT Review]——SPI

• Basic Introduction

By reading the data sheet, I found that the PSOC 62S4 PIONEER KIT has six Serial Communication Blocks (SCBs), all of which can be configured in SPI mode, supporting Motorola SPI, TI Secure Simple Pairing (SSP) and Naional Microwire, operating at up to 25Mhz. When acting as a host, it supports up to four slaves, supports 8-bit or 16-bit data frame size, and supports changing the baud rate during data transmission.

2. Introduction to main APIs

1.SPI initialization cyhal_spi_init()

Among them, the cyhal_spi_mode_t enumeration is

2. SPI event enable cyhal_spi_enable_event()

Among them, the cyhal_spi_event_t structure is

3. SPI Simple Program

Function description: Send data starting from 0. Each time data is sent, the data value increases by 1, the LED flips and prints out the data value.

Program Description:

1.SPI initialization, MOSI pin is P0_2, MISO pin is P0_3, clock pin is P0_4, chip select pin is P0_5, 8-bit data frame, clock polarity and phase are both 0, high bit first, SPI is configured as master

2. Set the SPI clock frequency to 1Mhz

3.SPI sends data

PS:

1. When using a logic analyzer to analyze, it was found that when using cyhal_spi_transfer() and cyhal_spi_transfer_async() to send data, the parsed data was incorrect. I don't know if it was due to the logic analyzer, the wiring, or some other reason.

ADC initialization cyhal_spi_init(), typo, looking forward to better trial
