&par Example Description

This example shows how to use M0CP peripheral to complete CORDIC vector operation.
Press KEY1 to start test. If operation is done,USART1 peripheral will print information.

z = arctan(y/x)
note:result [-16384, 16384] <-> [atan2(-PI/2), atan2(PI/2)]

When the program start address is changed, the macro definition M0CP_FLASH_ADDR may also be synchronously changed to the start address + 0xBC.

The USART1 is configured as follows:
    - TX:PA9, RX:PA10
    - BaudRate = 115200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled

&par Hardware Description
  - Close J2 and J3
  - Close J6 and J8
