The ESP32 has been a go-to microcontroller platform for a while now, thanks to its versatile capabilities, integrated Wi-Fi and Bluetooth connectivity, and low power consumption. It’s ideal for a wide ...

GPIO交换矩阵是外设输入和输出信号和pad之间的全交换矩阵。 它可以实现任意的信号映射，使得任何一个外设输入或输出信号都可以连接到任何一个GPIO pad上。 这样可以避免硬件设计时的限制，提高IO的利用率。 下图是ESP32中IO_MUX和GPIO交换矩阵的示意图： ...

We’re always interested in the latest from the world’s semiconductor industry here at Hackaday, but you might be forgiven for noticing something a little familiar about today’s offering from Espressif ...
