 When powering the Nucleo-32 board with an external 5 V power supply, you need to either open solder bridge 9 or you can connect the ''VIN'' pin to 5 V as well. If the solder bridge remains closed, the ''T_NRST'' pin of the disabled ST-LINK controller will constantly reset the main controller by pulling down the ''NRST'' pin. With 5 V supplied to both ''+5V'' and ''VIN'', the ST-LINK part has enough power to pull up ''T_NRST''. After the development phase, as part of deploying the microcontroller application, SB9 should be opened and the wiring changed to supply power only to ''+5V'' (or ''+3V3'') in order to keep power consumption low.

	The value for the high-speed external clock (HSE) speed is set by the ''HSE_VALUE'' preprocessor definition. The default value is 8 MHz. You shouldn't need to change this. The clock speed multiplier for is given by ''RCC_CFGR_PLLMULL'' (RCC = Reset and Clock Control, PLL = Phase Locked Loop). When setting up a new project, GNU MCU Eclipse Plugin pops up a dialog where CPU parameters such as Flash memory size, RAM size, and clock speed can be specified. The given value for the clock speed is then placed into the compiler command line argument -DHSE_VALUE.
