In this link I see a few GPIO's are pin'ed out on the breakout board.
Then I went to here
https://github.com/espressif/ESP8266_MP ... ster.h#L39
To find that GPIO2 can also function as a UART1_TXD backup.
I used FUNC_SELECT on that pin to assign GPIO2 to be FUNC_UART1_TXD_BK and BAM, I can now use it as UART1 to send Debug Data.
#define PERIPHS_IO_MUX_GPIO2_U (PERIPHS_IO_MUX + 0x38)
#define FUNC_GPIO2 0
#define FUNC_I2SO_WS 1
#define FUNC_U1TXD_BK 2
#define FUNC_UART1_TXD_BK 2
#define FUNC_U0TXD_BK 4
#define FUNC_UART0_TXD_BK 4
The UART1RXPin I do not have on the Wemos has it requires GPIO 11/08/06 and none are available on this board. But for just sending debug data. Perfect.
Now with UART_SWAP swaping the pins for RX/TX to RTS and CTS, I need to find a function to send UART data from those to make the message appear in the "SCREEN" command console. Haven't tested it to see if it would work but fingers crossed
