Which allow for higher speed baud rates, even when other libraries create interrupt On Teensy 3.2, 3.5, 3.6, Serial1 and Serial2 have 8 byte transmit and receive FIFOs,

Serial connection confusion is so common thatĭon't feel bad if you get it mixed up. The serial signals on the Rx and Tx pins are 'TTL level'. But when using XBAR, Teensy transmits when the pin is logic highĪnd pauses transmission while the pin is low. Meaning Teensy is allowed to transmit data when CTS is low, and must pause when CTS Pins, so care should be used to avoid conflicts if using alt pins. XBAR alternate pins each override use of one of the primary Each serial port can make only oneĬonnection to the XBAR for flexible pin routing, so on each port you can assign an XBAR pin toĮither CTS or RX, but not both. XBAR pins may be used with attachCts() or setRX().

USB and Serial1 (pins 0 & 1) are not shared on Teensy. Is use of code designed for Arduino Uno withĪccesses the USB only. The most common issue with serial ports on Teensy Modbus controllers, serial interface displays and many other serial devices. The Teensy boards have 1 to 8 hardware serial ports, which may be used toĬonnect to serial devices, like GPS receivers, XBee & ESP Wifi modules,
