STLED524 Evaluation Kit (5 x 24 Matrix LED Display Driver)

STEVAL-LLL001V1

Overview

The STEVAL-LLL001V1 board is designed to demonstrate the features of the STLED524 intelligent matrix LED display driver with a 5 x 24 matrix of SMD white LEDs incorporated on the board.

Two boards can also be joined using the on-board connectors to drive a 10 x 24 LED matrix.
The board is driven by the USB control board for interface with the graphical user interface (GUI), but there is also an SPI interface connector on the STEVAL-LLL001V1 which can be used for customized control.

Main features

Operating input voltage from 2.7 V to 5.5 V
Drives 5 x 24 LED matrix
Luminance separately adjustable for each LED by internal registers in 255 steps
Internal registers capable of storing two patterns
4-way scroll function with a possibility to lock column data
255-step PWM dimming

SPI interface
Integrated step-up converter with adjustable output voltage
Integrated LDO with 3.1 V output at 80 mA
CSP 56 bumps 0.4 mm pitch 3.4 x 3.0 mm
RoHS compliant

How to use the samples in WDK
Hi guys, can the samples in WDK run in a virtual machine? I want to practice developing drivers on Virtual PC. I have mastered the environment and basic debugging methods. I want to load the system in
Please help me find out what is the difference between the same circuit and different chips
Could you please tell me the difference between TLC2254CN and TLV2764IN? What is the difference between the output of these two chips in the circuit? Which chip is better?
MFC opens the serial port, and the stm32 microcontroller stops running
I wrote a program that sends data to the serial port after pressing a stm32 button, and uses MFC to read the serial port data; but when MFC opens the serial port connected to the microcontroller, the
Ask a strange question about the timer, I hope an expert can answer it
wince5.0, Samsung 2440 board, set timer 0, interrupt once every 625ms. In debug state, each interrupt is about 625ms, with high accuracy. However, when the program is put on the board and run, the int
