Part Number: TLC5940 Hi!
The TLC5940 is power by a 5V domain for VCC and the BLANK signal have a pull-up to 5V.
To prevent random channel turn-on, BLANK should be pulled high firstly. For this reason I have a pull-up to the 5V.
The LED:s are powered by…

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…
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 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…
