Function Documentation
◆ print()
| void print | ( | const char * | p | ) |
Send ASCII symbol or symbols through UART
TX mode have to be enabled
◆ UART_enableRX()
| void UART_enableRX | ( | bool | is_enable | ) |
Enable or disable RX of UART
- Parameters
-
is_enable when 1(true) UART RX enable, 0 (false) UART RX disable
- Note
- Some caravel CPU enable and disable UART TX and RX together
◆ UART_enableTX()
| void UART_enableTX | ( | bool | is_enable | ) |
Enable or disable TX of UART
- Parameters
-
is_enable when 1(true) UART TX enable, 0 (false) UART TX disable
- Note
- Some caravel CPU enable and disable UART TX and RX together
◆ UART_popChar()
| void UART_popChar | ( | ) |
Pop the first ASCII symbol of the UART received queue
UART_readChar() function would keeping reading the same symbol unless this function is called
◆ UART_readChar()
| char UART_readChar | ( | ) |
Wait receiving ASCII symbol and return it.
Return the first ASCII symbol of the UART received queue
RX mode have to be enabled
◆ UART_readLine()
| char* UART_readLine | ( | ) |
read full line msg and return it
◆ UART_sendChar()
| void UART_sendChar | ( | char | c | ) |
Send ASCII char through UART
- Parameters
-
c ASCII char to send
TX mode have to be enabled
◆ UART_sendInt()
| void UART_sendInt | ( | int | data | ) |
Send int through UART the int would be sent as 8 hex characters
- Parameters
-
c int to send
TX mode have to be enabled
