STM32 NUCLEO板用户手册(UM1724)

翻开目录，找到Getting Started

Getting started
Follow the sequence below to configure the STM32 Nucleo board and launch the demo
software:
1.Check the jumper position on the board, JP1 off, JP5 (PWR) on U5V, JP6 on (IDD),
CN2 on (NUCLEO) selected.
2. For correct identification of all device interfaces from the host PC, install the Nucleo
USB driver available on www.st.com/stm32nucleo, prior to connecting the board
3. Connect the STM32 Nucleo board to a PC with a USB cable !(R)type A to mini-B!¡¥ throug
USB connector CN1 to power the board. The red LED LD3 (PWR) and LD1 (COM)
should light up. LD1 (COM) and green LED LD2 should blink.
4. Press button B1 (left button).
5. Observe how the blinking of the green LED LD2 changes according to clicks on button
B1.
6. The demo software and several software examples on how use the STM32 Nucleo
board features are available on www.st.com/stm32nucleo.
7. Develop the application using the available examples.
开始
按照下面的顺序配置STM32Nucleo板和运行演示
软件:
1。检查跳线位置在板上,JP1(处于OFF状态),JP5(PWR)在U5V端,JP6(在IDD端),
CN2(NUCLEO端)。

2。为正确识别所有设备接口从主机电脑,安装而言,连接之前,

JP1的配置

JP1 is configured according to the maximum current consumption of the board when
powered by USB (U5V). JP1 jumper can be set in case the board is powered by USB and
maximum current consumption on U5V doesn!¡¥t exceed 100mA (including an eventual
extension board or Arduino Shield). In such condition USB enumeration will always succeed
since no more than 100mA is requested to the PC. Possible configurations of JP1 are
summarized in
Table 5.

Table 5. JP1 configuration table
Jumper state             Power supply                    Allowed current
JP1 jumper OFF                                                300 mA max
USB power through CN1
JP1 jumper ON                                                 100 mA max

JP5的配置

When the board is power supplied by USB (U5V) a jumper must be connected between pin
1 and pin 2 of JP5 as shown in 板卡由USB供电/或者外部供电的跳针配置。
Table 7.

JP6配置：

JP6 (IDD)
Jumper JP6, labeled IDD, is used to measure the STM32 microcontroller consumption by
removing the jumper and by connecting an ammeter. Jumper ON: STM32 microcontroller is powered (default). Jumper OFF: an ammeter must be connected to measure the STM32 microcontroller
current. If there is no ammeter, STM32 microcontroller is not powered.OSC clock

ON的时候默认，

OFF的时候，需要外接一个电流表。

也就是说，这里可以测量板卡的电流？
