I seem to have tried everything to get any sensor output or serial monitor output from this board. I’ve tried the Blink sketch and the KX13x Arduino Library sketches without any results. I can program my board through USB and physically see the blinking of the onboard LED but I cannot see any Serial Monitor output. I’ve even tried two PCs with different model numbers, and both Arduino IDEs. I can confirm the sketch runs on the board but cannot receive any Serial Monitor output on my PC. I am using Windows 10, at the correct baud (115200). I’ve tried multiple plugging into COM ports, reading multiple COM ports, using PuTTY. I have all prerequisite software installed. Connectors are fully seated.
Having performed the following process:
-
Open Device Manager.
-
Click on View in the menu bar and select Show hidden devices.
-
Locate Ports (COM & LPT) in the list.
-
Check for the COM ports by expanding the same.
I find the device STM32 BOOTLOADER (while physically seeing the blue LED on the device blinking). The text “STM32 BOOTLOADER” is grayed out.
Windows 10 Enterprise LTSC
SparkFun Thing Plus - STM32
SparkFun Triple Axis Accelerometer Breakout - KX134 (Qwiic)
Do you have any suggestions on getting this board working?
