demo leds toggling on ping and jammer code on ch.20
defined topology
reworking stm32 projects
adding openwsn configured project
openmotestm's driver and project
interrupt function's return type, add flash.c and flash.h
making stm32 start. still problems with unhandled interrupts..
adding project configuration files
disable interrupt before initial peripherals
Merge branch 'develop_openstm32' of https://github.com/openwsn-berkeley/openwsn-fw into develop_openstm32
replace function name "uart_isr_tx" with "uart_tx_isr","uart_isr_rx" with "uart_rx_isr"
enable the NVIC interrupt after having a callback set
replace USART1_IRQChannel with UART4_IRQChannel
enabling NVIC at the correct place.
