Conclusion – Arduino INPUT_PULLUP recap In this tutorial you’ve seen how to properly use pull up and pull down resistors for your Arduino sensors, and when to use the INPUT_PULLUP option for the pinMode function. To recap, you have 3 choices, depending on the default state you want ...
You can control the mode of any pin using the pinMode() function. For example: pinMode(PIN_D6,OUTPUT); The first parameter is the pin number to configure and the second parameter must be either INPUT or OUTPUT. Often pinMode() is used in the setup() section to configure all the dig...

Arduino library for fasterdigitalWrite()using direct port manipulation and macro for ease in pin assignmentsfor constant pin numbers. It also provides fasterpinMode()anddigitalRead()functions as well as it adds adigitalToggleFast()function.
hi Bodmer, My pins are defined in custom config this way: #define ST7789_DRIVER // Full configuration option, define additional parameters below for this display #define TFT_WIDTH 240 // ST7789 240 x 240 and 240 x 320 #define TFT_HEIGHT ...
