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

1. Select the driver file that matches your operating system from the list below, download it, and extract it. You can also visit the FTDI Chip official website for additional FTDI driver versions.

2. Connect the device to your PC, open Device Manager, and install the FTDI driver (the screenshot below uses Windows 10 as an example). (Note: On some systems, you may need to install the driver twice for it to take effect. The unrecognized device is usually named M5Stack or USB Serial.)

For MacOS users, before installation, please check System Preferences -> Security & Privacy -> General -> Allow apps downloaded from: -> App Store and identified developers option.
