contiki - Thingsquare Router-Node -


i´m newbie thingsquare

i'm traying create ip64 gateway mb851 board (stm32w108cc microprocessor)

i send , receive data (ipv6 radio) using 2 mb851 boards thingsquare udp-multicast example.

i modified mist-mb851 platform include enc28j60-arch.c file implement platform code of spi functions called enc28j60 driver modified ip64-conf.h include enc28j60 driver , fallback interface

include "ip64-eth-interface.h"                                        include "enc28j60-ip64-driver.h"                                      define ip64_conf_uip_fallback_interface ip64_eth_interface  define ip64_conf_input                  ip64_eth_interface_input  define ip64_conf_dhcp                   1  define ip64_conf_eth_driver             enc28j60_ip64_driver

i modified contiki/platform/mb851 include stm32 peripherallibs create spi driver

the enj28j60 driver tested

i compile thingsquare router-node example when initialize dhcp process

ip64_init();--->ip64_ipv4_dhcp_init();--->ip64_dhcpc_request();--->handle_dhcp();--->send_discover();

nothing happens

debugging code when tcpip_ipv6_output(); function call send packet function ip64_6to4(...); fails , don´t know why

best regards

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
