README
======
This README discusses issues unique to NuttX configurations for the ST NucleoF401RE board

This README discusses issues unique to NuttX configurations for the ST NucleoF401RE board
from ST Micro (http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1577/LN1810/PF258797)
Microprocessor: 32-bit ARM Cortex M4 at 84MHz STM32F104RE
Microprocessor: 32-bit ARM Cortex M4 at 84MHz STM32F104RE
Memory: 512 KB Flash and 96 KB SRAM
I/O Pins Out: 37, 17 On the Connector
Network: TI CC3000 Wifi Module
ADCs: 1 (at 12-bit resolution)
Peripherals: 10 timers, 2 I2Cs, 2 SPI ports, 3 USARTs, 1 led
Other: Sleep, stop, and standby modes; serial wire debug and JTAG interfaces
Expansion I/F Ardino and Morpho Headers
It breaks out the Tx, Rx to connect to a FTDI TTL-232RG-VREG3V3-WE for the console and
wires in the spark LEDs and serial flash to the same I/O as the sparkcore. It has a Jlink
compatible Jtag connector on it.
Uses a STM32F103 to provide a ST-Link for programming, debug similar to the OpenOcd
FTDI function - USB to JTAG front-end.
Wireless WIFI + SD Card SDIO via a "CC3000 WiFi Arduino Shield" added card
