&par Example Description
This example provides a small application in which system sends and receives data by polling
though using SPI firmware library. All received information will be displayed by serial assistant.
To use this example, you need to load it on two APM32 boards (let's call them Board A and Board B)
then connect these two boards through SPI lines and must A and B to GND.
When compare buffer is no difference,The LED2 is on.
The phenomenon of data interaction process can be displayed using serial assistant.
Master Slave
CLK PA5 PA5
NSS PA4 PA4
MISO PA6 PA6
MOSI PA7 PA7
&par Hardware Description
using USART2(TX:PA2、RX:PA3) to Master.
- USART2 configured as follow:
- BaudRate = 115200
- Word Length = USART_WordLength_8b
- Stop Bit = USART_StopBits_1
- Parity = USART_Parity_No
- Hardware flow control disabled (RTS and CTS signals)
- Receive and transmit enabled
