Pcb Circuit Boards are widely used in automotive electronics, including power control systems, safety control systems, body electronics systems, and communications.
In the future, automotive electronics will move toward the trend of big functions, namely: mobile communications, multimedia leisure, safe driving assistance (including automatic driving), ride comfort, energy saving (including electric vehicles), protection and preservation, all of which pose challenges to the PCB industry. At the same time, it also provides good development opportunities. For example, autonomous driving will bring large-scale applications of millimeter-wave radar, so the demand for high-frequency PCB boards for radars will be significantly increased, and the value is significantly higher than traditional PCB boards; BMS in electric vehicles is one of the core components. PCB board is one of the basic components of BMS and will benefit from the development of electric vehicles.

If you want to change the LED pin, please modify the hardware.h file. If you want to modify the brightness of the LED, modify the Timings section definition in globals.h. This design has two external buttons, one is to select the working mode, and the other is the power switch. When you press the mode button for more than 1.5 seconds, enter the automatic mode and all the preset modes will be automatically demonstrated.
Eight LEDs are connected directly to Vcc and do not require a current limiting resistor. This production uses a synchronization timer and uses sleep to save power.
