Is there documentation that defines the functionality of different LEDs on Meadow board?
Especially I’m interested in knowing what does this LED indicate? First it blinks, then it blinks faster until it is practically ON all the time. It might take minutes to hours before this happens after launching the program.
The board is being powered via the 5V-pin. Ground is in the ground pin. The power comes from an USB charger. I’ve used one with 1 A and another one with 2 A capacities.
The board communicates with three external devices with serial-UART, I2C and SPI-buses. Two of the external devices are powered with 3.3 V external regulator (1117). Meadow and one device use the 5V power.
It goes OFF and does not blink anymore when I plugin the onboard micro-usb-port to an USB-port of a computer.
I might have a problem that Meadow / some of the external devices / the code stops working (running) after some period of time (that varies between a couple of hours to several hours). The possible problem might occur about the same time the LED starts going ON, but I’m not sure yet.
Nevertheless, I would like to know what does this LED indicate. Thanks!
