Does the board already have pull-up resistors on the i2c lines, or do I need to add them? Thanks!

R robsoles Well-known member Jan 17, 2016 #2 The I2C library uses the internal pull-ups in Teensy's processor - effectively plug and play.
R robsoles Well-known member Jan 17, 2016 #4 sorry, had a squiz at the circuit and just did not look at those (glaringly obvious) 2k2 resistors clear as crystal on the schematic - that I2C library enables the pullups on the I2C pins on the MCU tho doesn't it?
