5V/3.3V). At this time, when observing from the vicinity of the LCD screen pin
array, it is normal to see that there is an internal light bead lit up, indicating that
the backlight is normal.
If the backlight still does not respond according to the above operation, it is
speculated that there may be a hardware circuit malfunction.
Question 2: After receiving the product, the wiring test has a bright back,
but there is no display screen
Analysis:
Backlit indicates that the power supply is connected correctly and there is
no short circuit phenomenon, but if the screen needs to be displayed normally,
SPI communication needs to be completely normal, including factors such as
correct matching of SPI signal wiring and program burning, and normal operation
of the microcontroller.
It is recommended to use the demo program we have tested for the first
time. The program should not be modified and try to find the same
microcontroller development board for testing as much as possible. This can
eliminate the factor of dim dots caused by program modifications. At this time, it
is also important to pay attention to whether the demo compilation and download
prompt is successful, whether the development board is running normally, and
whether the wiring is wired according to program requirements.
If the demo does not match your microcontroller and must be modified to
run, it is recommended to use the_ Example modification test for SoftWare suffix
words, which will be more effective than_ HardWare is more likely to succeed.
If the picture still cannot be displayed normally after many times of tossing
and turning according to the above steps, use the necessary tools such as
multimeter/oscilloscope/Logic analyzer to analyze and test the signal, and
contact our technicians for help.
Question 3: The product can display, but the backlight brightness
fluctuates and is unstable
