UM3180 GUI usage GUI usage The main window can be divided into different sections that are detailed in the following paragraphs. Figure 7. Main window sections Top bar Top bar reports the STSW-LLL014GUI version, the board connection status, and the firmware revision. Figure 8.
UM3180 Device toolbar Figure 9. File configuration manager and example of configuration file Device toolbar The indication “Bridge connected” into the top bar confirms that a STEVAL-LLL014M1 board is properly connected and recognized. Once the communication is established, the GUI checks the ALED7709 presence.
UM3180 Device settings For detailed explanation of each bit, please refer to the ALED7709 datasheet. Device settings In the “Device settings” section, there is the possibility to configure the way of working of ALED7709. It contains the following subsections: • fault management •...
UM3180 Channels settings Figure 15. Output configuration subsection Output configuration subsection controls the bits inside the OUTCFG register. “Temp Sensing” can be DISABLED simply acting on the bit; the NTC can be left connected. Figure 16. Boost configuration subsection Boost configuration subsection adjusts the bits inside the BOOSTCFG register. In this subsection, it is possible to adjust the boost switching frequency;...
UM3180 Hardware Controls window If Global mode is selected, PWM and GAIN of CH1 are applied to all the active channels. While in Local mode, each channel uses the setting of its PWM and GAIN. Each bar can be modified dragging it by the mouse, selecting it by double-click and writing the needed value with the keyboard.
UM3180 Register configuration window Figure 19. Hardware Controls window Each bar can be modified dragging it by the mouse, selecting it by double-click and writing the needed value with the keyboard. The relative jumpers in J5 must be closed to connect the signals from MCU to the correspondent ALED7709 pins.
UM3180 Log window Figure 22. Register configuration window The REGISTER column identifies the register using the same datasheet name. The ADDR column is the register address, and the DATA column is its content. Both values are in hexadecimal format. The numbered columns give the name of each bit of every register; for a detailed description of each bit functionality please refer to the datasheet.
