Hello, I'm new to NodeMCU 8266 12E V3

Using the arduino interface by installing ch340G drivers, or switching from cable to machine, between mac and windows.
I can not write any blink code.

I already did, grounding between D8 and GND
I already did, I pressed the flash I clicked the rst and kept my finger on the flash and it did not work
I held the flash and put the USB cable and tried and nothing too.
Already, I solved the ESP-12
Already, I solved the ch340g

looks like you are not using the correct port. Does /dev/cu.usbserial-40 disappear if you unplug your nodemcu? Did you try other ports offered?
