^^^^^^^^^^^^^^
|
||||
|
||||
By default, all configurations use UART0 which connects to the USB VCOM
|
||||
on the DEBUG port on the LM4F120 LaunchPad:
|
||||
|
||||
UART0 RX - PA.0
|
||||
UART0 TX - PA.1
|
||||
|
||||
However, if you use an external RS232 driver, then other options are
|
||||
available. UART1 has option pin settings and flow control capabilities
|
||||
that are not available with the other UARTS::
|
||||
|
||||
UART1 RX - PB.0 or PC.4 (Need disambiguation in board.h)
|
||||
UART1 TX - PB.1 or PC.5 (" " " " "" " ")
|
||||
|
||||
UART1_RTS - PF.0 or PC.4
|
||||
UART1_CTS - PF.1 or PC.5
|
||||
|
||||
NOTE: board.h currently selects PB.0, PB.1, PF.0 and PF.1 for UART1, but
|
||||
that can be changed by editting board.h
|
||||
|
||||
UART2-5, 7 are also available, UART2 is not recommended because it shares
|
||||
some pin usage with USB device mode. UART6 is not available because its
|
||||
only RX/TX pin options are dedicated to USB support.
|
||||
|
||||
UART2 RX - PD.6
|
||||
UART2 TX - PD.7 (Also used for USB VBUS detection)
|
||||
|
||||
UART3 RX - PC.6
|
||||
UART3 TX - PC.7
|
||||
|
||||
UART4 RX - PC.4
