摘要:STM32L-的Discovery和32L152CDISCOVERY套件,,幫助你發(fā)現(xiàn)STM32L超低功耗的特點(diǎn),,并制定和分享您的應(yīng)用程序。它們都是基于單個(gè)STM32L152RBT6 STM32L152RCT6,,包括一個(gè)ST-LINK/V2嵌入式調(diào)試工具接口,,LCD(24段,,4公共端),指示燈,,按鈕,,呈線性接觸傳感器或touchkeys。

The STM32L-DISCOVERY and  32L152CDISCOVERY kits help you to discover  the STM32L ultra low power features and to develop and share your applications.They are based on an STM32L152RBT6 and an STM32L152RCT6, respectively; and include an ST-Link/V2 embedded debugging tool interface, an LCD (24 segments, 4 commons), LEDs, pushbuttons, a linear touch sensor or touchkeys.

方案特點(diǎn):

STM32L152RBT6 (128 KB Flash memory,
16 KB RAM, 4 KB EEPROM) or
STM32L152RCT6 (256 KB Flash memory,
32 KB RAM, 8 KB EEPROM) microcontroller in
an LQFP64 package
On-board ST-Link/V2 with selection mode
switch to use the kit as a standalone
ST-Link/V2 (with SWD connector for
programming and debugging)
Board power supply: through USB bus or from
an external 3.3 or 5 V supply voltage
External application power supply: 3 V and 5 V

The demonstration software is preloaded in the board Flash memory. It uses the built-in IDD measurement and touch sensing feature of the STM32L-DISCOVERY or the
32L152CDISCOVERY to automatically measure and display on the LCD the microcontroller consumption in run and low-power modes.

The latest versions of the demonstration source code and associated documentation can be
downloaded from www.st.com/stm32l1-discovery.
