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

• Basic Introduction

By reading the data sheet, it is found that the PSOC 62S4 PIONEER KIT has six Serial Communication Blocks (SCBs), five of which can be configured in UART mode. It is a full-featured UART with an operating rate of up to 8Mbps; it supports automotive single-wire interface (LIN), infrared interface (IrDA) and smart card (ISO7816) protocols, which are small variations of the basic UART protocol; in addition, it also supports 9-bit multiprocessor mode, allowing addressing of peripherals connected through common RX and TX lines; it supports common UART functions such as parity error, interrupt detection, frame error, etc.; the 256-byte FIFO allows greater CPU service delay.

• Main API Introduction

1. UART initialization cycyhal_uart_init()

in:

(1) cts is the input signal of the transmitter. When activated, it indicates that the slave is ready for the master to transmit data. rts is the output signal of the receiver. When activated, it indicates that the receiver is ready to receive data. If you need to use these two features, you need to call cyhal_uart_enable_flow_control() function to enable them.

(2) The cyhal_uart_cfg_t structure is

2. Debug print UART initialization cy_retarget_io_init()

Among them, the parameters of cy_retarget_io_init_fc() are as follows

3. UART event enable cyhal_uart_enable_event()

Among them, the cyhal_uart_event_t enumeration is

3. UART Simple Program

Function description: After power on, it prints Hello World!!! and the LED starts flashing. Press the Enter key and the LED stops flashing. Press it again and the LED continues flashing.

Code description:

1. Initialize the printing UART, set the transmit pin to P3_1 (CYBSP_DEBUG_UART_TX), the receive pin to P3_0 (CYBSP_DEBUG_UART_RX), and set the baud rate to 115200 (CY_RETARGET_IO_BAUDRATE)

2. When UART receives '\r', it stops or starts LED flashing according to the current LED flashing status and prints relevant information

Can MDK be used as a development tool? Or do I need other tools?

According to the official documentation, you can use

But it needs different configuration, you can see the official document below

I use the official modustoolbox-eclipse

Thank you very much. I haven't come into contact with it yet. Is it easy to get started?

I have just come into contact with this product. I have only come into contact with 51 microcontrollers and STM32, N32, GD32 before.

It's easy to learn. It's basically packaged. You just need to call the HAL library. But there's not much information. It's mostly in English.
