Add BananaPi-BIT Development Board Support #1810
Conversation

Why not include the ADC pins (A0-A19) or the touch pins (T0-T9)? |
|
ADC pin is included in P0-P19.Such as P1 is IO32(ADC1_CH4) P2 is IO33(ADC1_CH5) and so on |
|
@yelvlab so if I want to do an Chuck. |
|
The A## is a specific designation, that means ADCX_CHANNEL_Y. Making up labels just causes portability problems. |
|
@stickbreaker Because our board uses a special shape and connector design, we changed the pin name to a unified Px, and because the intended use of the board is the primary user, we will unify the pin names. Avoid the same IO with multiple names, causing users to worry. |

@lbernstone I know it ,but the user of our board definition is relatively primitive. We are considering avoiding the user's doubts (the same IO multiple definitions A0 and P0), and unifying the pin name definition, then the Analog function or the Digital function of each pin will have The document is written.Later, we will also release a less customized development board, continuing the ESP32 Ax or Dx definition method and Arduino UNO appearance, but we are not ready yet, you can preview it first, the following is github https://github.com/yelvlab/BPI-UNO32 |

This define is used to convert from A[n] to gpio pin. Since you are choosing not to define analog input pins should you change both NUM_ANALOG_INPUTS and analogInputtoDigitalPin() to reflect this choice?
#define NUM_ANALOG_INPUTS 0
#define analogInputToDigitalPin(p) -1Chuck.

I think the definition here can be retained, because we not only have to consider the primary users, but also the people with certain Arduino and ESP32 programming development foundations, they can not use our prepared P(n) in their own code , from the line definition A (n) such a pin, and, our board does not give up the ADC function.

Done! Where can I get one of those boards? I collect all kinds of ESP based things (not TTGOs and similar though). Your board seems to follow the MicroBIT thing :) don't have such yet |

Hi ,@me-no-dev You can find it on AliExpress.AliExpress Banana pi bit |
|
thanks @yelvlab will get one :) |
