● STM32 development board (STM32F767IGT6) FAQ (frequently asked questions)
1: Can't find the USB to serial port?
There may be several reasons for this problem:
1) The development board kit is not powered.
In this case, please check whether the blue power light in the lower right corner of the development board is on, if not, press the power switch. The power indicator must be on for the computer to find the USB to serial port. In addition, this microcontroller development board does not support JLINK power supply, and it is not recommended to use ST LINK to power the development board kit.
2) The wrong USB port is inserted.
To use the USB to serial port, the USB cable must be plugged into the USB_232 interface in the lower left corner of the development board as the picture shows:
3) The USB driver is not installed.
Please install the CH340G driver. The CH340 driver is located in the CD-ROM: 6, software data\software\CH340 driver (USB serial port driver)_XP_WIN7 shared folder.
2. Comprehensive test experiment, the touch screen is inaccurate/untouchable.
In this case, please calibrate the touch screen.
Calibration method: press and hold KEYO, press reset, release reset (KEYO has been held down during this process), and when it is loaded into Touch Check, the system will enter the touch calibration interface (only for 2.8/3.5 resistive screens). Release the KEYO, then use the pen tip to tap the center of the cross on the screen in turn to complete the calibration. When the calibration is complete, the screen will prompt: Touch Screen Adjust OK, indicating that the calibration is complete.
3. Serial port experiment (experiment 3) no return of data sent
This problem can generally be caused by the following reasons:
1) The serial port is wrong.
Please select the correct serial port (see picture).
2) No new line is sent (or no carriage return is entered).
Friends who use SSCOM and XCOM, note that you must check: Send a new line, as shown in the figure:
4. Some interfaces cannot be exited during the comprehensive test experiment.
In the comprehensive test experiment, some interfaces, such as drawing, notepad, e-book, etc., do not have a return button on the screen.
At this time, we can press the TPAD touch button in the lower right corner of the microcontroller development board to exit the current interface and return to the main page. interface. as the picture shows:
TPAD is a capacitive touch button, which can be input with a touch of a finger. In the comprehensive experiment, in any interface, you can return by pressing this TPAD button.
