I have tried all available examples in ESP-IDF related to USB communication, including both the Host CDC and Host USB libraries, but I am unable to establish communication with my UPS device. I can successfully communicate with other devices using known drivers like CP210x, but I am strugglin...
我使用的是 esp32-s3 使用usb host-cdc-acm 历程。 从机用的是 stm32f407 标准库 的usb-cdc-vcp 历程, 从机和PC端连接,可以识别到设备, 从机和ESP32相连识别不到设备??? 程序错误点: 这个函数 (_check_client_opened_device(client_obj, dev_addr)) 返回来错误标志esp_err_t usb_host_device_open...
程序1:采用IoT Solution中的例程usb host-cdc_acm_host,用于连接一个cdc设备实现读和写 程序2:采用idf中的udp_server例程,用于对一个目标端口进行读和写 单独运行程序1和程序2都一切功能正常,但是将两个程序结合,即同时运行usb host和udp,usb则会报PORT_EVENT_ERROR的错误后重新初始化usb设备,这个报错后重新初始...
在运行示例程序 esp32-s2-usb-host-cdc 时,当与设备通讯有段时间之后,串口打印错误信息: [0;33mW (1922332) : BULK IN, dir: 1, err: 0x103[0m 之后发现无法收到USB的数据了,请问这是什么原因导致出现这个错误的?下面是原来的代码 void xfer_in_data()...

ESP32-c3内部带有1个USB Serial/JTAG控制器,可用于下载flash程序、JTAG调试、虚拟串口通信等功能。硬件框图如下: 其主要特性如下: 支持usb全速设备(12Mbps),不支持高速(480Mbps) 固定为CDC-ACM设备(Communication Device Class - Abstract Control Model)
1. 使用两个ESP32模块：一个作为HOST连接多个USB-HID设备，另一个作为DEVICE连接上位机。这两个ESP32...
Hi, Seen CDC USB host drivers for FTDI and SiLabs chips in new S3/S2/C3 ESP32 variants. Although these do work, it seems that the CH34x USB serial chip brand is quite widespread and in use by really almost anything nowadays in many devic...
