The latest version of the black board, smaller size, more stable, longer exposure time range, 17 levels, minimum 10us, maximum 2000ms, 42mm long, 18mm wide.

It is recommended to purchase CH340 USB-to-serial module together, so that the shopkeeper can test the connection before delivery. After you get the goods, install the driver, and connect the USB port of the computer directly to test.

A sample program (not a CCD driver) for STM32F103C8T receiving CCD module data can also be provided for your reference

1: communication protocol, send @c****#@, where **** is a four-digit decimal number (sent characters are ASCII code format), change the value of ****, can realize different functions, transmission, integral time change, etc. Baud rate 256000 (other baud rate can be specified before delivery, no special requirement 256000 baud rate).

0080,@ C0080 #@, read CCD data instruction to transmit hexadecimal pixel data 3648*2=7296 per frame, frame header 0x3c, 0xC3,0x33, 0xCC, frame tail 0x4F, 0x4B

2: can be customized, such as size measurement, liquid level, density measurement, position measurement, laser beam highlight measurement and so on.

3: main frequency 2M, sampling rate 0.5m, 12-bit AD, can add algorithm to achieve specific functions, it is estimated that it can be processed 100 times per second results.

4: LCD is customized, you can customize various sizes of LCD display, display waveform, exposure time, extreme point, width and so on, easy to debug the optical system, or real-time detection, LCD refresh rate can reach 60 times per second.

5: High speed SPI data output can be customized.

 

You can use EXCEL, or TXT format to save the collected image data. The left column is pixel coordinates, and the right column is pixel voltage sampling value (12-bit AD, full range 3.3V for 4096)
