SPI 사기 전에는 일단 이걸로 테스트 해봐야겠군..

minicom이나 리눅스용 putty로 쇼를 해도 안되서
결국에는 arduino 설치하고 시리얼 터미널로 테스트하니 응답한다
Both NL & CR로 해주어야 응답한다. (망할!)

For Arduino, must type the AT command like this Serial1.print("AT+GMR\r\n"); Not like this: Serial1.println("AT+GMR"); So the hardwareSerialMonitor sketch will not work now. v0.9.5.2 ai-thinker-0.9.5.2-9600.bin The default baud rate is 9600 ai-thinker-0.9.5.2.bin The default baud rate is 115200 AT+GMR AT version:0.21.0.0 SDK version:0.9.5 v0.9.5 beta ai-thinker-0.9.5.bin AT+GMR 00200.9.5(b1) compiled @ Dec 25 2014 21:40:28 AI-THINKER Dec4 |

알리에서도 124,124원 하는 고가의 키보드
일단 usb 선이 잘린놈이라 고쳐야 하는데, 고치는 김에 겸사겸사 트랙볼 키보드(세진)도 같이 손을 봐야겠다.
특이하게도 키보드 높이가 2단계로 조절이 가능할 것으로 보이고, 하단에 말아서 대충 넣을 곳도 보인다.

esp32는 arduino ide를이용해서 하는데
대충 esp32 설치하고 나서 예시를 찾아보는데 기본 예시에서는 freertos가 없는 것 같다.
esp-idf(IoT Development Framework)을 나중에 설치해봐야 할 것 같은데..?
