1. 当固件执行到启用 WIFI 的时候,CHIP_EN 脚电压快速下降。怀疑是这个原因导致的重启。CHIP_EN已经使用了RC延迟电路。 2. 怀疑是供电部分的问题。但是改为使用外部电源供电,问题依旧。 3. 查看 CHIP 的VDD, VDD3P3_CPU,VDD3P3_RTC 等脚上的电压。重启时基本稳定,只有10ns级别的正弦波动。 发现以下几个解...
2.2 复位 ESP32-C3 系列芯片的复位可使用 CHIP_EN 管脚。当 CHIP_EN 为低电平时复位。 2.3 外部晶振 ESP32-C3 系列芯片固件仅支持 40 MHz 晶振。 2.4 天线 其实天线部分是一个核心部分,需要认真对待,但是这个测试板我目的是为了把ESP32-C3当成替代STM32的一种方案,所以天线部分并没有针对性的去计算,预留了...

Re: ESP32-C3 needs external flash chip? by ESP_LJH » Thu Feb 23, 2023 6:30 am Please check if power supply is not less than 500 mA. Add RC not only R at CHIP_EN, add a pull-up at GPIO2, add a series inductor 24 nH at XTAL_P, use ESP32-C3F chip and add 1 uF at...
