Here is an example of using the second UART on ESP32 C3 Remember to connect the ultrasonic TX to pin4 (ESP32 C3 RX) and the ultrasonic RX to pin5 (ESP32 C3 TX) Code: Select all // ESP32 C3 SERIAL1 (second UART) void setup() { Serial.begin(115200); Serial1.begin(115200,...
Code:Select all #ifdefined(__linux__) || defined(__APPLE__)#else#endif but as this code may be compiled also for windows and maybe BSD I would prefer to have something like "#if defined(__esp32__)" but I didn't found any documentation regarding this. Someone has done something si...
I want to upload my code to esp32 without using any ide. As far as I have understood I am suppose to upload bin files to my esp32 but the question is how? I coded my project in PlatformIO. The bin files that are generated are bootloader.bin, firmware.bin, littlefs.bin and partition...
How do I get access to the error code causing my failure? The send always returns success, and then the failed callback doesn't give any useful information. Seems like that's all the information you get. ESP-NOW works asynchronously, i.e. you enqueue data to be sent via esp_now_...
Have you ever wanted to take a peek inside your code to see why it's behaving the way it is? Traditionally in ESP32 projects, you would have had to add endless print statement to try figure out what was going on, but there is a better way!
This concludes my introduction to VS Code and ESP-IDF. In my opinion, they make for a powerful combination of development tools, and, together, provide a comfortable and simplified development environment for ESP32 applications, regardless of the OS you're using. Using VS Code with ESP-IDF ...
Esp32c3 Version v2.0.11 IDE Name Arduino IDE Operating System Windows Flash frequency 40MHz PSRAM enabled yes Upload speed 115200 Description Because of some issue with deep sleep, GPIO wake up and internal resistors, I found the lines I want to change in ESP32 IDF. ...
