For example, on the Arduino Uno, you could only have SPI on pins 10, 11, 12, and 13. The SPI, I2C, UART, PWM, and DAC are no longer associated with specific pins. The pins of the ESP32 are much more modular than those of the Arduino: You can “ attach “ a UART, I2C, SPI, and PWM peripheral on the pins you want. So, in reality, there are fewer possible interfaces for each device. The ESP32 already uses some peripherals in its essential operation. They are much more numerous than on a classic Arduino Uno board. To interact with the modules, sensors or electronic circuits, the ESP32, like any microcontroller, has a multitude of peripherals. You can use them, but you must be careful when setting a logic state (3.3V or 0V) with an external pull-up or pull-down resistor. The strapping pins are the GPIO0, GPIO2, GPIO12 (MTDI) and GPIO15 (MTDO). Depending on the voltage available on these pins, the ESP32 will start either in BOOT mode or in FLASH mode. They are used to put the ESP32 in BOOT mode (to run the program written in the flash memory) or in FLASH mode (to upload the program to the flash memory). Some pins have a unique function when starting the ESP32. They also do not have internal pull-up and pull-down resistors ( pinMode(36, INPUT_PULLUP) or pinMode(36, INPUT_PULLDOWN) cannot be used). Pins GPIO36 (VP), GPIO39 (VN), GPIO34, and GPIO35 can only be used as input. Fortunately, there are other UART interfaces available. They can be useful for programming the board without a USB but with an external programmer instead. If you use them, you will not be able to upload programs to the board or use the serial monitor via the USB port. The GPIO1 (TX0) and GPIO3 (RX0) pins are used to communicate with the computer in UART via USB. Here's an example of how Arduino structures their "1.5 library format" library repositories:Īs you can see, the library is in the root of the repository.For this reason, these pins are not available on uPesy ESP32 boards. So to proceed you just have to restructure the repository folder structure in your clone, commit the changes, then push them. If you don't care about backwards compatibility with Arduino IDE 1.0.x you can use the "1.5 library format" which allows you to put the library source files in a subfolder named src: ![]() Note that this doesn't necessarily mean the source files for your library must be in the root of the repository. Allow you to submit your library for inclusion in the Arduino Library Manager index, which also requires this folder structure.ZIP Library., which requires the library to be in the root of the. Allow people to download the repository from GitHub using the Clone or download > Download ZIP button on the repository home page and then install the library via Sketch > Include Library > Add.Not only will this will solve your issue with using the repository with the Arduino IDE, it will provide a couple additional benefits: You need to put the library in the root of the repository. Is there a suggestion on how to do this from those out there, who develop Arduino libs? On the other side, if I choose to permanently move the Foo_lib folder up a level after cloning, now my README files are left in the previous folder and Git freaks out that bunch of files are deleted and the whole thing is a mess. (Not that this is hard but it kills me TBH :) However, I end up with the following folder structure My Documents > Arduino > libraries > +GitHub_Repository_Name+ >Foo_libĪnd now, since my Foo_lib isn't directly under the libraries folder, Arduino IDE wouldn't recognize it.įor the 3rd party libs I have always did the download and copying the lib to the libraries folder manually, but, this is an ongoing work on the library I am developing myself, so I don't want to make changes, then copy the changes to the tracked folder. I point the GitHub software to My Documents > Arduino > libraries >.After doing so and trying to download/clone back the tracked project to my PC I do, one of the thousand ways, like the following, If I want to track this folder using GitHub, I need to give it a repository name. My Documents > Arduino > libraries > Foo_lib ![]() In the Arduino side, my library files should reside in the following structure, dictated by Arduino, so the Arduino IDE could recognize it. I know Git and I know (a bit of) Arduino and it seems how Arduino structures his library files make it quite hard to track the changes using GitHub without copying files around all the time. I am wondering how to use Github for developing an Arduino library so the library would be recognizable by the Arduino Library straight after the. ![]()
