Re: ESP32-S3R8
1,ESPS3R8 USB转串口下载,芯片需要特殊配制么? 不需要特殊配置,插入电脑会显示一个 USB-Serial-JTAG 设备,一个串口设备,直接使用串口设备对应的 COM 号下载即可(如果应用中占用了 USB 口(例如启用了 U 盘功能),需要先手动进入下载模式) 2.JTAG端口只能调试,不能下载么? 可以下载:https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-guides/jtag-debugging/index.html#upload-application-for-debugging 3.串口下载...

Re: Using ESP_INTR_FLAG_SHARED with the GPIO driver
Thank you for your suggestions.
From IDF 5.0, it already supports config some GPIO API to IRAM, and also adds `__attribute__((always_inline))`

Re: ESP32-S3 USB OTG - USB Hub support?
USB Hub is not supported by Host Driver now. Would you please tell us the application scenario? Which kind of device users want to connect through HUB? and how many? this will help us evaluate the priorities of this driver development

“使用OTG转接头插入U盘” 需要注意 dev-kits 的 usb 接口是不能向外供电 5V 的,只能输出 5V

Re: 关于uvc驱动摄像头的问题
会准备多次传输请求,排队传输。写 1 也可以,对照一下是否有吞吐率降低

Re: 关于uvc驱动摄像头的报错问题
bulk:transfer size in each urb same as frame buffer
如果开了,每发起一次 bulk 传输,会请求一帧的数据,所以会占用更多的 RAM
如果不开,会发起多次 bulk 传输来获取一帧数据

Re: ESP32C3内部WiFi与蓝牙进程如何彻底关闭?
每隔10ms发送一次方波是如何定时的?建议通过硬件定时器实现,因为延时函数不准确
