High-brightness RGB LED array with LED error detection based on STP24DP05 and STM32

STEVAL-ILL015V1

Overview

The STEVAL-ILL015V1 demonstration board provides a platform for the testing and evaluation of STMicroelectronics Power Logic LED driver STP24DP05.

The STP24DP05 device is a 24-bit constant current LED sink driver with output error detection, suitable for applications such as largearea displays and full-color board panels where improvement in RGB LED resolution and reduction of system cost are important.

Main features

3 jumpers to simulate the shorting of 3 LEDs
3 jumpers to simulate the disconnection of 3 LEDs
Input 7.5 V - 18 V, current 0.7 A
Highly efficient ST1S010 DC-DC switching power supply
Buttons and knob to control the board
Test points on the board for each important signal aide laboratory evaluation

Two STP24DP05 devices (TQFP48 package) connected to 3 X 16 RGB high brightness LEDs
Using a cost-effective internal HS oscillator.
STM32 microcontroller
Mini USB connector for interconnection with a PC GUI.
Error and over-temperature flag for each LED driver
JTAG interface for microcontroller firmware changes/updates

How to trace the reason why the program enters FaultISR!
static voidFaultISR(void){ // // Enter an infinite loop. // while(1) { }}When debugging a program, this function is often entered!How to effectively track where it went before?
Emitter follower problem
[i=s]This post was last edited by paulhyde on 2014-9-15 09:04[/i]I want to use transistors to make an emitter follower. What type of transistor should I choose? [i=s] This post was last edited by paul

Help, the SDRAM write process in 5502 takes 210ns, how to increase the speed
In TMS320VC5502, it takes 210ns to write to SDRAM, which is simply impossible. I would like to ask the seniors how to solve this problem? I set the relevant registers of EMIF, such as WRITE SETUP, WRI
There are some previously downloaded documents on the computer.
