The above screenshot shows pretty-much exactly what you should see when you successfully Flash the Debug configuration of our blank PlatformIO Project to your ESP32 Development Board. Starting the Debugger

tbreak tells the Debugger that whenever we place a Breakpoint in our code, we want execution to halt and the IDE to interrupt so that we can debug our code. This informs PlatformIO that we are using the ESP-PROG debugger function, and defines the conditions under which we want the Debugger to halt execution. You can write comprehensive, real-world programs for your ESP32 microcontrollers, configure them for Debugging, Flash them every time you need to directly to your ESP32 Development Board, and step through them as much as necessary to diagnose problems. This screenshot shows the Debug view of Visual Studio Code, denoted by the “Play” icon with the little insect on it.Due to the stylish nature of the ESP Fishing Jumper, you can pair it with a pair of jeans and a t-shirt for a spring day or wear it with a large coat and other winter clothing for the perfect amount of warmth in the height of the cooler weather. With five different comfortable threads used within the jumper to create the design, you can be sure you’re getting the best of the best when it comes to the quality of the material as well as the overall shape and cut. Now, every time execution Halts, the value of those Variables ( presuming they are visible to the execution scope at which the program halts) will be immediately visible for you. success_moderated": "Your comment was posted successfully. We will publish it in a little while, as our blog is moderated.", The highlighted item is the current Build Configuration, followed by (in braces) the name of the Project.

So, now that we can Debug a Program on an ESP32 Development Board, let’s make something simple so we can interrogate a few Variables/Members on the Debugger. It is strongly recommended that you don’t plug or unplug any wires without first disconnecting the power from your ESP-PROG board. Now, the above ini file defines two identical configurations, but with two different names ( Release and Debug respectively)

Remember: If you previously connected the Programmer Interface to a 5v input pin, and set it to 5v mode, you don’t need to connect Pin 1 or 3/5/7/9. There has certainly been a resurgence in the popularity of angling knitwear since ESP began bringing us semi-regular Terry Hearn videos, though these jumpers have never gone out of fashion entirely. First came the very popular green version and now, However, now we need to know how to Flash the Program ( built with whichever Build Configuration we have selected) to our ESP32.

Note that upload_speed for most ESP32 Development Boards supports a nice high Baud rate of 921000. If you have issues with this, lower the value to 115200, which is slower but more compatible. What Port Numbers Do I Need? If in doubt about which COM port to use, we can quite easily determine which Port is the one we need. However, when you connect the Debugger interface of the ESP-PROG, along with its own 3.3v power and GND pins, everything will work perfectly. If you’ve ever written code for an MCU before, there’s a 99.99% chance that you have resorted to the use of “debug messages” to interrogate the values of important variables/members within your program. Serial.println("This is an annoying debug message!")If you have a group of related variables to monitor, this is arguably the most efficient way to do so. Once you have identified the correct Port Number, place the name as shown in the Available Ports list ( screenshot above) in both the monitor_port and upload_port settings in your platformio.ini file.

The above screenshot shows the contents of the default platformio.ini file, created each time you make a New Project. Now, in the above modified ini file, we define a common section ( which is not itself a Build Configuration) and share the properties of that section with both Build Configurations. Pins 3, 5, 7, and 9 are all Ground pins. You can choose whichever one of them you wish, but we only need to connect one of them.All we need to do to build and Flash the Debuggable version of our Program is switch our Build Configuration to our Debug Config.
