// Supports serial port baud rate setting at different frequencies.
|
|
// Added support for printf
|
|
// Serial port receive command features have been added.
|
|
// Fixed printf first character missing bug
|
|
//V1.4 amended description
|

// 1, modify the initialize serial IO bug
|
|
// 2, modify the USART_RX_STA makes serial port maximum bytes received 2 of 14
|
|
// 3, USART_REC_LEN, defines the serial port the maximum allowable number of bytes received (not more than 2 of 14)
|
|
// 4, the modified EN_USART1_RX method
