According to the datasheet, ESP32 provides three universal asynchronous receivers and transmitter (UART) ports such as U0, U1, and U2. By default, only UART0 and UART2 can be used. To use UART1, we have to redefine the pins. Because default pins of UART1 such as GPIO9 and GPIO10 a...

The ESP32’s BLE functionality enables it to act as a server or a client in Bluetooth communications. It can handle tasks like reading and writing services. It can also encrypt connections and establish the Serial Port Profile (SPP) connections for data transmission in UART-BLE pass-through mo...

With the ESP32 you can decide which pins are UART,I2C, orSPI– you just need to set that on the code. This is possible due to the ESP32 chip’s multiplexing feature that allows to assign multiple functions to the same pin. If you don’t set them on the code, the pins will be ...

On completion of transaction, ESP peripheral pulls Handshake pin low. If completed transaction had a valid TX buffer, then it also pulls Data ready pin low. gpio_hand_shake: handshake拉高,表示esp32端装载了一个接受或者发送buf,然后host端检测handshake是高,就可以发送数据了,esp32在spi传输数据的时候...
Specifically, we will cover the usage of 1x UART, 1x lIC, 1x lIS, 1x SPI, 11x GPIOs (PWM), 9xADC, 1x User LED, 1x Charge LED, 1x Reset button, 1x Boot button, and, for the XIAO ESP32S3 Sense, 1x B2B Connector (with 2 additional GPIOs). By the end of this tutorial...
