stm32f103的CAN的时钟主频是36M,分9频就是4M,在除以(5 + 2 + 1)得到500K的波特率。 注意:stm32cubemx生成的CAN代码是不带过滤器的,需要自己手动添加。 CAN之数据帧格式 代码部分 CAN初始化 CAN_HandleTypeDef hcan1; CAN_FilterTypeDef sFilterConfig;//CAN初始化:/* CAN init function */ void MX_CAN_I...
I’m working on a project with an STM32 microcontroller and an ESP8266 wifi modem (running AT firmware). My goal is to connect to the AWS IoT MQTT broker using a secure TLS connection. I have a few specific questions: Is it possible to establish a secure MQTT connection to AWS IoT us...
Re: 计划做一款基于ESP32 S3的调试工具,具备工业485、CAN调试功能 @Gentlepig 目前RGB565就够用,T133的确挺好,还能省个触摸芯片,目前想联网还需要外加WIFI,成本大约得100左右。联网功能计划使用阿里云物联网平台,可实现远程调试,只用申请个key就可以,如果消息多就需要收费,目前看来远程调试消息并不多。 最近编辑记录...
So I'm running an ESP32 system and an ESP8266. Both are doing some disco light controlling stuff. I want to send GET requests to the ESP8266 like "192.168.2.81/LEDON" from my ESP32. But at the same time I want my ESP32 to handle GET Requests from my phone or anything else. ...
As ESP8685 based modules are mentioned in ESP32-C series on https://www.espressif.com/en/products/modules, so I am curious to know whether can I use ESP8685WROOM06 with ESP Rainmaker framework. If yes then what are the steps to use it? Also can I use ESP8285 or ESP8266 Mo...
RS232/RS422/RS485通信接口区别RS-232、RS-422与RS-485标准只对接口的电气特性做出规定,而不涉及接插件、电缆或协议,在此基础上用户可以建立自己的高层通信协议。例如:视频服务器都带有多个RS422串行通讯接口,每个接口均可通过RS422通讯线由外部计算机控制实现记录与播放。
Re: how can i use pwm? #22985 By eriksl - Sat Jul 11, 2015 1:46 am No, that's not it. I am referring to this file. It's in the SDK. At least in 1.1.2 and 1.20. It seems to come from the application example, they didn't remove the references to the examples. Code:...
Hello, i have a use case where i have approx. 8 ESP32S3 connected on a CANbus. My idea is to upload new firmware using one of them to open a AP, with a Websocket. This is what i have now. Then i would like the others to recieve it over the CANbus ? - the OTA dosent car...
