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...
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...

but it was necessary because my hardware is a module with an ESP32 wrover integrated into a sim800L, then the main communication pins are already in use. I tested pins 0 and 14 in a simple serial communication with an arduino to see if they will be able to work, it had no problem....
