The full range of on-board hardware features helps the user to evaluate all the peripherals (USB, USART, digital microphones, ADC and DAC, TFT LCD, MIPI DSI LCD, LDR, SRAM, NOR Flash memory device, Octo-SPI Flash memory device, microSD card, sigma-delta modulators, CAN transceiver, EEPROM) and to develop applications. Extension headers allow easy connection of a daughterboard or wrapping board for a specific application. An ST-LINK/V2-1 is integrated on the board, as an embedded in-circuit debugger and programmer for the STM32 MCU and the USB virtual COM port bridge. System requirements Windows OS (XP, 7, 8, 10) or Linux or macOS USB Type-A to Micro-B cable Development toolchains (a) Arm Keil : MDK-ARM (a) IAR: EWARM (a) GCC-based IDEs (free AC6: SW4STM32, Atollic TrueSTUDIO and others) Demonstration software The demonstration software, included in the STM32Cube package corresponding to the on- board MCU, is preloaded in the STM32 Flash memory for easy demonstration of the device peripherals in standalone mode.The latest versions of the demonstration source code and associated documentation can be downloaded from the www.st.com web page. a.
