Part Number: TLC5940 Hallo,
I have made a designed base on a daisy chain of 15 TLC5940.
The project is working since about 1 years whitout problem. But today when I power on the board, it happens that one LED was on and the remainder was off which has…
Part Number: TLC5940 Hello,
I’m a student from KU-Leuven university in Belgium and for a project I use 3 TLC5940's to drive a 16x16 RGB Led matrix. I want to use the STM32CUBE IDE to write the software.
Now because my software skills are not…
From TLC5940 sample driver (bit bang) by Aidan Holmes ( https://github.com/AidanHolmes/tlc5940 ),
there is SCLK 1 to 0 code only first time on reset routine. It can prevent from this behavior.

'Reset pin values' GPIO.output(self…
Part Number: TLC5940 Hi,
My customer want to make a solution of LED driver, but the boost voltage is 200V, current sink is 200mA per channel, 8-channel in total.
Can I use TLC5940 and tie two channels together to generate 200mA current sink, and use another…
Part Number: TLC5940 Hi,
I have developped my board based on TLC5940 as you can in the joined picture.
I have cascaded 15 of this IC. having finishe the development I order the board and start doing some Test. It happen out of the 10 board that I order…
Part Number: TLC5940 I'm an newbie for tlc5940 . I got TLC5940 EVM from my boss. According to the datasheet,1 GS Data Output Cycle consists of 4096 pulses.
I got a sample and sample code of TLC5940 EVM( USBv0.7_sourceCode, MCU: TUSB3210,software :LED…
Part Number: TLC5940 Hi team,
I have a question for maximum cascaded devices.
I understand that the maximum number of cascaded devices is 40.
For example, if the clock speed is quite low, will the maximum number change?
Is it a maximum of 40 under any…
Part Number: TLC5940 Hello,
Is there a TI-maintained Python library available for interacting with the TLC5940 chip? I'm especially interested in Python libraries that allow Raspberry Pis to interact with the TLC5940.
I found at least two libraries…
Part Number: TLC5940 Dear Pros,
There are several questions about the driver IC of TLC5940:
1. TLC5940 is an SPI interface, can we don‘t use the GSCLK signal?
2. What is the difference between dot correction and grayscale control?Is it DC mode and…
Part Number: TLC5940 Hi team,
I have some questions about the absolute maximum rating of the output current.
It is written that Output current is DC 130mA.
Does this mean that it does not include instantaneous current such as power supply transient and…
