got a question. is it possible to call serialswap before initiating neopixelbus using the DMA method, and to still have serial receive available on GPIO13?

UART1 can only transmit.
Serial1 uses UART1, TX pin is GPIO2. UART1 can not be used to receive data because normally it's RX pin is occupied for flash chip connection. To use Serial1, call Serial1.begin(baudrate).
I was wrong. Serial.swap changes pines not uarts

that is correct
