Timer Camera - UIFlow MediaTrans

Feature Introduction

Use TimerCAM to implement low-power timing wake-up photography functions, which rely on Wi-Fi connection. The captured images will automatically be uploaded to the M5 cloud, and a unique token will generate a fixed HTTP interface. Other devices can access this interface to obtain the latest frame image and the current battery voltage status of the device.

Driver Installation

Connect the device to the PC and open the device manager to install the FTDI driver for the device. For Windows 10, download the driver file matching your operating system, and unzip it. Install it through the device manager. (Note: In some system environments, it may be necessary to install the driver twice for it to take effect. Unrecognized device names are usually M5Stack or USB Serial. Windows recommends using the driver files directly in the device manager for installation (custom update). The executable file installation method may not work properly.) Click here to download the FTDI driver
