8266那里用来deep sleep唤醒的吧，直接拉en的话rtc内存里的东西就没有了，32在deep sleep的时候能跑的功能更多，读IO或者自己唤醒自己就没必要单独拿一个脚了。

在Component config → ESP System Settings 下面没有找到 Channel for console output额？大佬有截图么？

只有带usb的芯片才能用吧，s2 s3 c3这些

我按照网上的一些代码使用esp32的lna，然后它应该是被adc1采样的吧，但是在启用WiFi之后，单次SENS_SAR_MEAS_START1_REG.SENS_MEAS1_START_SAR = 1之后到SENS_MEAS1_DONE=1的时间变得非常不稳定。 不使用WiFi的情况下，它一秒能吐个7k左右的采样，这和cycle算出来的结果也差不多吻合，但是一旦启动WiFi之后，这个数字就从剧烈波动 2: 17.970428 T: 1917.804077 3: 22.507694 T: 788.185852 0: 23.901028 T: 7240.023926 1: 26.151798 T...

What about improve the functional pin mapping? Many boot strapping pins and other pins that used by on board flash makes it hard for pin arrangement. More confusing, SDIO even overlapped with bootstrapping pins and have different pull-up/down requirements for a 3.3v flash... Also, the exists of thes...

Hi, I'm making something looks like bluetooth headset/speaker but to save battery energy as much as possible. So, in most time it stays quiet and working on BLE. Only when it's playing music, it turn to bluetooth classical. And this process makes sense to me. (I'm not familar with Bluetooth, if it's...

OK... After carefully inspected my breadboard, I found the problem... First, I replaced the LDO to AMS1117-3.3 by some ugly wire... Second, I miss connected RX to RX and TX to TX in the pcb.. after some dirty cut and reconnect it finally works... I'm wondering what I'm thinking at that time... :oops...

I removed the Li-on chip, shorted USB-VCC to LDO and I can feed ESP-32 is a lot more hot(40°C at least I feel). But still having no output in the terminal... Administrator@WIN-F5GR238P6RA MINGW32 ~ $ python -m serial.tools.miniterm --dtr 0 --rts 0 COM4 115200 --- Miniterm on COM4 115200,8,N,1 --- --...

Both RTS/DTR are active low, so to keep them high (ie EN pin high, ESP32 enabled) you will need "miniterm.py --dtr 0 --rts 0 /dev/ttyUSB0 115200" I will try this argument after I get my new LDO. (If you saw the --rts 1 --drt 1 in our docs somewhere, can you please tell me where? Will fix.) It's not...

Thanks a lot. I didn't notice this... I've seen this schematic for ESP8266 in some boards, and when I was drawing them, I read https://github.com/espressif/esptool/wiki/ESP32-Boot-Mode-Selection#automatic-bootloader and it says Make the following connections for esptool.py to automatically enter the...
