Product introduction:
This RGB module is equipped with ST's high-performance 8-bit MCU and related MOS tube driver circuit. Simply send simple commands to it through the TTL. Serial port to control the color and brightness of the RGB full-color LED.
Product parameter:
Power supply voltage: DC 3.3V-5V
Board indicator: power indicator
TTL baud rate: 9600
R, G, B: R represents red, G represents green, B represents blue
Driving RGB: suitable for driving a single RGB lamp bead with a common cathode or multiple lamp beads in parallel
Interface description:
R, G, B: Connect the three pins of RGB tri-color LED
GND: Connect to the common cathode of RGB
+-: input power
VCC: Connect to TTL 5V (it can be connected to the power supply port of the board)
RX: Connect the TX end of TTL
TX: Connect to TTL RX
GND: Connect to the GND terminal of TTL
Instructions for use:
Description of control instructions:
(1) Each instruction consists of 4 bytes of hexadecimal (hex) data, each generation; the meaning of the table is as follows:
Data (1) - Revelation logo (default is 0x1F)
Data (2) - channel number (0x01: red, 0x02: green, 0x03: blue)
Data (3) - Brightness value (range: 0x00--0x64, equivalent to 0-100 decimal) Data (4) - Check code (sum of the first three digits)
(2) This module includes manual light adjustment and the automatic flash function of the system. Send 1F0000 1F to turn on the automatic flash function
(3) Some manual light adjustment commands are as follows:
Set the red light 1% brightness: 1F01 0121
Set the red light 50% brightness: 1F 0132 52
Set the red light 99% brightness: 1F 0163 83
Set green light 1% height: 1F 020122
Set green light 50% brightness: 1F 02 3253
Set green light 99% brightness: 1F 0263 84
Set blue light 1% brightness: 1F 0301 23
Set blue light 50% brightness: 1F 033254
Set blue light 99% brightness: 1F 03 63 85
The setting rules of other colors and brightness are the same as above, basic steps; start bit -> channel number> brightness value converted to hexadecimal> add the first three digits:
For example: red light 0% brightness: 1F01 0020
Green light 75% brightness: 1F 024B 6C
Blue light 100% brightness: 1F 03 64 86
This controller is suitable for controlling a single RGB lamp bead of common cathode type or an RGB lamp bar in which multiple lamp beads are connected in parallel. Regarding the current-limiting resistance of the LED lamp, you can choose the appropriate resistance value according to your own actual needs. The controller controls the color and brightness of L ED by accepting serial port commands. The VCC, TX, RX, and GND of the USB-to-TTL serial port module are connected to the VCC, TX, RX, and GND of the RG controller (if the command does not respond, try to exchange TX And RX), the B, G, B, GND of the output end are connected to the R, G, B, GND of L ED respectively,-the default is automatic flashing mode when powered on,
Open the serial 0 debugging software (such as SCOM32) on the computer to send the lamp adjustment command to manually adjust the lamp.
