|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

|
|
^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
现在,请前往 :doc:`../../get-started/index` 中的 :ref:`get-started-step-by-step` 章节,查看如何设置开发环境,并尝试将示例项目烧录至您的开发板。

|
|
|
|
.. attention::
|
|
|
|
|
|
|
|
|
|
ESP32-DevKitM-1 搭载的模组为单核 MCU 模组,烧录应用程序前,需要在 :ref:`menuconfig <get-started-configure>` 中使能单核模式 (:ref:`CONFIG_FREERTOS_UNICORE`)。

电源选项
|
|
|
|
|
----------
|
|
|
|
|
|
|
|
|
|
开发板可从以下三种供电方式中任选其一:
|
|
|
|
|
|
|
|
|
|
* Micro USB 供电(默认)
|
|
|
|
|
* 5V / GND 管脚供电
|
|
|
|
|
* 3V3 / GND 管脚供电
|
|
|
|
|
|
|
|
|
|
.. warning::
|
|
|
|
|
|
|
|
|
|
- 上述供电模式 **不可同时连接**,否则可能会损坏开发板和/或电源。
|
|
|
|
|
- 建议选择第一种供电方式:Micro USB 端口供电。
