WebSep 2, 2024 · For STM32 Blue Pill with Arduino Core, digital pins are named based on its port and pin number, such as PB1, PA10. There is no A10, I assumed that you mean PA10 (which was marked on the Blue Pill PCB as "A10" (for Port A Pin 10) due to limit space on the PCB. To use it as a digital pin, simply use PA10 to address it, that is:

The DDR register, determines whether the pin is an INPUT or OUTPUT. The PORT register controls whether the pin is HIGH or LOW, and the PIN register reads the state of INPUT pins set to input with pinMode ().
WebMar 9, 2024 · A wire is connected from a pin on the Arduino, to an LED via a resistor (to protect the LED from high current), and finally to the ground pin (GND). ... - this function … Arduino (Atmega) pins default to inputs, so they don't need to be explicitly declared as inputs with pinMode() when you're using them as inputs. Pins configured this way are said to be in a high-impedance state. Input pins make extremely small demands on the circuit that they are sampling, equivalent to a series … See more Often it is useful to steer an input pin to a known state if no input is present. This can be done by adding a pullup resistor (to +5V), or a pulldown resistor (resistor … See more There are 20K pullup resistors built into the Atmega chip that can be accessed from software. These built-in pullup resistors are accessed by setting the … See more Pins configured as OUTPUT with pinMode() are said to be in a low-impedance state. This means that they can provide a substantial amount of current to other … See more
WebIf you're building a printed circuit board to connect to the Arduino, do the same thing - collect all of the PCB grounds together and wire that to one Arduino Ground pin. If you're using a manufactured shield, you may have to get creative about collecting your grounds. A tiny breadboard is one way.
