ESP32-C3 系列芯片,搭载 RISC-V 32 位单核处理器。不过可以跑多线程,下面就是两个线程。程序中避免有过多的延迟函数😘😘😘 6.1 源码分享 int testdata0 = 10;int testdata1 = 0;void CpuLoop(void *pvParameters){while(1){Serial.println("cpu1 "+String(testdata0));testdata1 ++;if(testdata...
BOOT(IO09)管脚上电前不能下拉,ESP32会进入下载模式。 使用到IO08管脚进行设计,不建议外部直接下拉,因为在下载烧录时,IO08管脚为低电平,不能使用串口进行下载。 IO12(GPIO12)、IO13(GPIO13)在QIO模式下为SPI信号SPIHD和SPIWP复用,为了增加可用GPIO数量,开发板选择采用2线SPI的DIO模式,IO12、IO13并未连接flas...
The Arduino Nano ESP32 (with and without headers) is a Nano form factor board based on the ESP32-S3 (embedded in the NORA-W106-10B from u-blox®). This is the first Arduino board to be based fully on an ESP32,and features Wi-Fi®, Bluetooth® LE, debugging via native USB...
Before you can start working with BLE communication on the ESP32 and Arduino Nano 33 BLE Sense, you need to set up the required software and libraries. Here's how you can do this using both the Arduino IDE and the Arduino Web Editor: ...
