TimerCAM/Unit CAM - UIFlow

Feature Description

Use the device to connect the TimerCAM/Unit CAM through the GROVE interface to achieve command control of the camera's UART transmission of images and preview them on the M5CORE screen, or configure a timed shooting and upload to the cloud function (returning a fixed HTTP API).

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.

Download the Firmware Burning Tool

Please download the M5Burner firmware burning tool according to your operating system. Unzip and open the application.

Work Mode

UIFlow supports configuring the camera to switch between UART and Wi-Fi working modes. The Wi-Fi mode supports timed shooting and automatically uploading images to the M5 cloud and returning an image call interface (URL). In UART mode, it supports users "to obtain image frames through UART communication with other main control devices" and modifying image parameters. The following will use the main control CORE as an example, connect UnitCAM, and obtain image data.

Example

from m5stack import *
from m5ui import *
from uiflow import *
import unit

setScreenColor(0x222222)
timercam_0 = unit.get(unit.UNITCAM, unit.PORTB)
unitcam_0 = unit.get(unit.UNITCAM, unit.PORTB)
timercam_token = None

def buttonA_wasPressed():
  global timercam_token
  timercam_0.set_wifi('xxxxx', 'xxxxx')
  timercam_0.set_upload_time(5)
  timercam_0.set_mode(timercam_0.CLOUD_MODE)
  pass
btnA.wasPressed(buttonA_wasPressed)

def buttonB_wasPressed():
  global timercam_token
  timercam_token = timercam_0.get_token()
  if timercam_token:
    lcd.qrcode(('camera.m5stack.com/timer-cam/image?tok=' + timercam_0.get_token()), x=72, y=32, width=176, version=6)
  pass
btnB.wasPressed(buttonB_wasPressed)

def buttonC_wasPressed():
  global timercam_token
  timercam_0.set_show(True)
  timercam_0.set_image_size(timercam_0.SIZE_320_240)
  timercam_0.set_mode(timercam_0.UART_MODE)
  pass
btnC.wasPressed(buttonC_wasPressed)
