High-brightness LED array driver with diagnostics for automotive applications based on STAP16DPPS05 and STM8A

STEVAL-ILL060V1

Overview

The STEVAL-ILL060V1 is a high brightness LED array driver evaluation board with diagnostics based on STMicroelectronics’ automotive-grade low voltage, 16-bit constant current LED sink driver STAP16DPPS05.

The LED driver is configured and controlled through an 8-bit automotive-grade STM8A microcontroller via an SPI interface. An A5974D DC-DC converter, also automotive-grade, provides the voltages and power needed for overall operation of the board.

Main features

6 - 24 VDC power supply with reverse voltage protection, short-circuit protection and input surge protection and standard DC jack input
Backward/forward transition switch to change modes
SWIM connector for MCU programing and debugging
Connector for LIN development and evaluation
Potentiometer to change brightness and speed of patterns
32 white LEDs (PLCC 4)

8 jumpers to simulate open-circuit error
4 jumpers, to simulate short-circuit error
USB-UART bridge to interface board with GUI
Demonstrates pre-configured patterns (with adjustable brightness/speed) such as rolling text, wave effect, dot sequence, etc. in stand-alone mode
Demonstrates basic mode or frame programming mode with GUI SW
RoHS compliant

How should I choose the frequency of the clock source and the baud rate of the transmission? Are there any rules? Why can it only be displayed correctly when I choose 32768HZ 9600 baud rate?
