The 6th pin is RTS, the power wire is +5V and the signal levels are 3. That means you need at least 4 pins - clock, data in, tft cs. If your HMI project was developed via 0. Using the Hardware Serial Ports The Teensy boards have 1 to 8 hardware serial ports, which may be used to connect to serial devices, like GPS receivers, XBee & ESP Wifi modules, Modbus controllers, serial interface displays and many other serial devices. But when we go deeper we understand that Arduino is not industry ready development board and its 8-bit CPU with a ridiculously slow clock and maybe not suitable for higher-level projects. 4 Compile and Upload the code Print Hello World in Serial terminal Code [crayon-5f5016c6a6849446708765/] Print data in the Serial from user input Code [crayon-5f5016c6a6854978450331/] Analog Read.
