HB LED driver with diagnostics based on LED2472G and STM32

STEVAL-ILL015V2

Overview

The STEVAL-ILL015V2 product evaluation board provides a platform to test and evaluate the power logic LED driver LED2472G from STMicroelectronics.

The LED2472G is a 24-bit constant-current LED sink driver with output error detection, suitable for applications such as large-area displays and full-color board panels where improvement in RGB LED resolution and reduction of system cost are important.

Main features

Two LED2472G devices (TQFP48 package) connected to 3 x 16 RGB high-brightness LEDs
STM32 microcontroller
Cost-effective internal high-side oscillator
JTAG interface for microcontroller firmware changes/updates
Mini USB connector for interconnection with a PC GUI
Test points on the board for each important signal aid laboratory evaluation
Buttons and knob to control the board

Error and overtemperature flag for each LED driver
3 jumpers to simulate the disconnection of 3 LEDs
3 jumpers to simulate the shorting of 3 LEDs
Highly efficient ST1S010 DC-DC switching power supply
Input: 7.5 V to 18 V, 0.7 A
RoHS compliant

MSP430F5529 study notes interrupt
When sending data in a non-serial port non-interrupt mode, it is inevitable that it will be interfered by other interrupts. The following method can be used to solve the problem: [list=1] [*]Save the
Two little-noticed details of the Nor and Nand flash boot methods of ARM9, s3c2440
[size=5]First of all, I know both booting methods and their principles very well. Here are two details: 1. When booting with nand flash, if the code is less than 4K, for example, 3.8K, after burning i
I wrote a small C++ program and want to run it on arm. How can I simulate it on windows? It's urgent. Thank you all.
I wrote a small C++ program and want to run it under arm. How can I simulate it under windows? It's urgent. Thank you or other methods. Linux is also OK. I mainly simulate arm4.

Is there anyone using the v2.0 development board? Why is there no reset pin? . . . . .
About LM3S811J-LINK Emulator
Do I have to buy a J-Link emulator for LM3S811? Can I not download programs to the board without an emulator?
Looking for partners
It's been almost two years since I graduated, but I still haven't found a direction for development. Fortunately, I work in the field of my major. My current location is Harbin. If there are colleague
