This article illustrates an easy way to sync ESP32 NTP and DS3231 RTC time so that ESP32 can use the RTC chip seamlessly in an application.
We troubleshoot a situation where the ESP32 cannot save JSON file to an SD card. The program in question is based on the ESP-IDF.
You might come across this error “C99 designator outside aggregate initializer” when you are compiling projects based on C code, but the compiler is expecting C++ code. For example, we…
Getting started with Arduino and ESP32 is much simpler these days, given that Espressif now supports it. Back in the day when ESP32 was a new chip in the market,…
The ESP-IDF contains functions for enabling Base64 encoding and decoding on ESP32. The encoding and decoding functions are actually built into the ESP32 ROM. The functions are accessible by using…
