Addressable RGB 60-LED Strip, 5V, 2m (High-Speed TM1804)
This 2-meter long strip contains 60 RGB LEDs that can be used in a single RGB LED. The waterproof, adhesive-backed stripe runs on 5 V high-speed TM1804 strips to form a longer run. LED for shorter segments.
Clearance: These high-speed TM1804-based LED strips are on the floor and will be discontinued when the stock is gone. They are being replaced by similar, newer WS2812B-based strips . The new strips can be used in the same way. However, the two types of strips have different, incompatible connectors, and the order of TM1804 colors are sent in the red-green-blue order while the WS2812B colors are sent in green-red -blue order.
overview
These RGB LED strips are an easy way to add complex lighting effects to a project. A dedicated driver IC for each LED independently. LED independent. The strips are available in lengths of 1 meter (30 LEDs), 2 meters (60 LEDs), and 5 meters (150 LEDs).

Using the LED strip

Each LED strip has four connectors (except for the 5 m strip, which does not have a power output). Can These can These These These These These, output These output These These These These These These These These These These These. The data and power output connectors are only used when chaining multiple strips together.
- Data The data The LED LED LED LED LED LED LED LED LED LED LED LED LED LED LED LED LED LED LED. is control the LED strip from a microcontroller, the LED strip has to be connected to the microcontroller, and the LED strip has to be connected to the microcontroller's I / O line. fit the female terminations on our premium jumper wires and wires with pre-crimped terminals.
- The power input is a center-positive barrel jack with a 2.1mm diameter pole. Our 5 V wall power adapter plugs for this well and for powering these LED strips. With all the LEDs on full brightness, the 1 m strip draws approximately 1.3 A, the 2 m strip draws approximately 2.6 A, and the 5 m strip draws approximately 4 A, so be sure to select a power source that can handle the strip's current Requirements.
- The data output connector is transparent. It can be used as a chain for multiple signals.
- The power output connector is a center-positive. 5.5 A- 2.1mm barrel connector that can be used to chain multiple strips in the same DC circuit. The 5 m strip does not have the maximum 5 m of LEDs in a single DC circuit.
The ground wires on all four connectors are electrically connected.
Note: The white connector is visible on one of the connectors Do not a good indicator of polarity. Please use the labeled connector diagram to help determine which pin is the signal. You can also verify the ground pin with a multimeter.
Chaining
Multiple LED strips can be chained together with other tapes. When they are connected, they can be controlled as one continuous strip.

With the 1 m and 2 m LED strips, it is possible to use a power supply. However, this can happen in the long chain of strips.
Do not chain more than 5 meters of LEDs in a single DC circuit. It is fine to make the chains with connected data lines, but you should power each five-meter section separately.
Cutting
The LED strip is divided into segments, with each 33.3 mm segment containing one RGB LED and its driver chip. The strip can be cut into two usable shorter sections. To access the connections on the side of the epoxy. The data connection is labeled OUT or IN , the positive power connection is labeled + VC , and the two pads in the middle are both connected to ground.

protocol
These LED strips are controlled by a high-speed one-wire protocol.
The default, idle state of the signal line is low. To update the LED colors, you need to transmit a series of high pulses on the signal line. Each high pulse encodes one bit: a short pulse (0.4 μs) represents a zero, while a long pulse (0.85 μs) represents a one. The time between consecutive rising edges should be 1.25-9.0 μs. After the bits are sent, the signal line should be held for 24 μs to send a reset command. Our tests indicate that the pulse widths do not have to be precise: 0.6 microseconds that determines whether the pulse is a 0 or a 1, and a wide range of pulse.

The color of each LED is encoded as a LED RGB (red-green-blue) order. Each brightness value is encoded as a series of 8 bits, with the most important bit being transmitted. LED color takes 24 bits. The first color is the LED input. The LED is in the strip, and so on.
24 bits represent the color of one LED in an addressable RGB LED strip. |
---|
To update all the LEDs in the strip, you should send all the colors at once with no pauses. If you send fewer colors than the number of LEDs on the strip, then some LEDs near the end of the strip will not be updated. For example, to update all 30 LEDs on a 1-meter strip, you would send 720 bits. If multiple strips are chained together with the same line (two chained 1-meter strips behave the same as one 2-meter strip).
Each RGB LED is controlled by the driver. IC that is the next IC using its data output line. The high-speed protocol of the driver for fast updates; our library for the Arduino is about 1.1 ms to update 30 LEDs, so it is possible to update 15 meters of LED strips faster than 60 Hz. However, constant updates are not necessary; the LED strip can hold its state indefinitely as long as power reserves connected.

Implementing the protocol on a microcontroller
Since this LED strip does not use a standard protocol, and the software has a microcontroller. Because of the sub-microsecond timing, the bit-banging code needs to be printed. If it is interrupted in your code are fast enough,
