The voltages available for the board are 3.3V, 3.7V and 5V. When the user uses the FMDlink board to debug the target IC, it can be It can be drecty powered by FMDink, and the supply voltage can be adjusted by satching the short-dircat cap. All power supplies of the FMDlink board are powered by a PC via a USB port of 5V. The first time you use it plug in the PC and the system will automatically install the driver and you can use it normally when the driver is installed 2. ![]() The connection between the PC host and the IDE develprent board is vem simple thatis, the standard USB interface, and there is no need to install additional drivers to use FMDlink Yellow LED (flashing): FMDlink is workingġ. Yellow LED (always on): FMDlink is in Boot mode, waiting for the firmware to be updated onlineĤ. Green LED (always on): FMDlink and PC are connectedģ. Red LED (always on): Power-on indication, at this time FMDlink did not communicate successfully with the PC.Ģ. (Note: There are four short-circuit points for J8, J9, J10, and J13, and only one of them can be shorted)ġ. J9: Target MCU 3.7V power supply selection ![]() J8: Target MCU 3.3V power supply selection P1: External Power external power input port J11: The program target MCU communication control ports, from top to bottom, are: USB1:The USB port is connected to the PC. ![]() IDE development environment: The upper computer software installation needs to be XP and above.
