Figure 2-1. ESP32 Pin Layout (, Top View) 意味着这是 ESP32 芯片的引脚布局图,采用的是 QFN 6*6 封装,而且是从芯片的顶部(俯视图)观察的布局。 1、This is the basic tutorial and should be used as template for other tutorials.中文(简体)这是基本教程,应用作其他教程的模板。 Build and Flash ...
打开芯片手册,然后找到pin definitions页面,这里主要查看一些特殊功能的引脚,例如adc、uart、spi用的是哪些io,确定下来后,把其它的通用IO也逐一确定即可,这些通用的IO后续绘制原理图时,还可以调整。 手册与设计资料:www.st.com 打开芯片手册,然后找到pin definitions页面,这里主要查看一些特殊功能的引脚,例如adc、uart、...
外设和GPIO对S3来说相对就弱一点,共计仅有56pin的MCU,其中45pin可编程 GPIO,通过IO矩阵重映射所有端口这点非常方便PCB layout,支持常用外设:SPI、I2S、I2C、PWM、RMT、ADC、DAC、UART、SD/MMC 主机控制器和 TWAITM控制器(兼容CAN 2.0B)。 站在定位为边缘AI和便携设备的MCU的角度,相对来说其需求会更聚焦为“...

In the Pin Layout section (2.1) of the datasheet, Pins 19 and 20 (SPIHD and SPIWP) of the ESP32C3-FH4 are labeled as NC (Not Connected). However, in the table in section 2.3, they are designated as default GPIOs. I tested using them as outputs, and it worked for me, but ac...

引脚定义 Pin Definitions Figure 2-1 shows the pin layout for 32-pin QFN package. 从图中可以看出来是第16脚,引线出来就行。 脚位定义说明 引线连接方式 至此,上电IO抖动问题就算完美解决了! GPIO0跟GPIO2无法直驱三极管问题 找不到根本原因,但更换了GPIO4以后就自己解决了。 可能是这两个脚位复用或者驱...

I baught an ESP32-WROOM-32D and now I try to find documentation to the pin layout but cant find it (I didnt know there are SO MANY different versions). My plan is to follow a tutorial to connect a round display (GC9A01) with the ESP32, because my Arduino is so slow and has not...
