Now, my goal with configuring my hardware to use GPIO6 (LP_I2C_SDA) and GPIO7 (LP_I2C_SCL) was that if I needed low-power / sleep capabilities, then I could do so without hardware changes, but if I ...

I have a ESP32 S3 WROOM 2 devkit 1C acting as Master and want to have the ESP32 WROOM32 to act as Slave. I have them connected with jumpers and attached the necessarry pull up resistors. I just wanted ...

I had one of those why-didn’t-I-think-of-it moments this week, reading this article about multiplexing I2C on the ESP32 microcontroller. The idea is so good, and so simple, that it’s almost silly that ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and WiFi — are all ...
