What are the points for attention in the use of STM32 series development boards
STM32 series of development boards to use what matters needing attention, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.
Power supply
Insufficient power supply will cause the touch screen to fail (4.3 inches)
) DC005 interface, power supply range is 6x24V
) VOUT2 (2X3 pin) can be 5V input or 5V output
When the load of the development board is heavy (high current), provide sufficient power supply.
Does not support simulator power supply
) the blue power light is on before using it.
Routine test
) Test according to the tutorial
) read README
) when testing routines, make sure that the development board B0B1is connected to GND.
IO usage
Connect the drain diode in parallel or the reverse current will burn the development board.
) the IO port must not be connected to more than 5V voltage
) do not use IO port to drive inductive load directly (click / solenoid valve / relay, etc.)
) IO selection, choose the appropriate IO port
) pay attention to anti-static electricity-first touch a piece of iron to release static electricity
