README
======
This README discusses issues unique to NuttX configurations for the
STMicro 32F3348DISCOVERY development board featuring the STM32F334C8
MCU. The STM32F334C8 is a 72MHz Cortex-M4 operation with 64kB Flash
memory and 16KB RAM. The board features:
- On-board ST-LINK/V2 for programming and debugging,
- High brightness LED dimming with buck converter
- One buck/boost converter
- Four user LEDs and two push-buttons,
- Easy access to most MCU pins.
Refer to http://www.st.com/en/evaluation-tools/32f3348discovery.html for
further information about this board.
Configurations
==============
nsh:
----
Configures the NuttShell (nsh) located at apps/examples/nsh.
powerled:
---------
This is a configuration for onboard high brightness LED dimming.
buckboost:
---------
This configuration uses apps/examples/smps and onboard buck/boost converter.
WARNING: current limit is not implemented!
