Adam Dunkels writes on 2/5/2017 on the Contiki mailing list:
[...] the original idea was that the application could just point the uip_appdata pointer to wherever the data was, but we then changed it so that the data actually had to be copied into the uip_aligned_buf buffer. So, yes, the network device driver should only need to read from this buffer. [...]
This change removes comments on the possibility of uip_appdata pointing somewhere outside the uip_aligned_buf. And it removes code in the SLIP drivers not necessary anymore.
Additionally it makes code in a SLIP driver optional that takes care of the Microsoft-specific CLIENT / SERVER / CLIENTSERVER chat.
The running serialdump does not recover from a disconnected device but
runs indefinitely with outputting anything. This makes it quit with a
proper error message.
termios i_flags were not initialized and could be set to arbitrary values
this resulted in unpredicted behaviour of the output like additional
newlines
Using clang (on osx) yields to some warnings
(conversion between signed/unsigned, unused variable)
which gcc would only produce when used with -Wall.
This commit fixes those.
The leds API did not work in some cases. E.g. with the following sequence:
leds_off(LEDS_ALL);
leds_toggle(LEDS_GREEN);
leds_off(LEDS_ALL);
the green LED was remaining on after the last call.
This was caused by the toggle feature made synonymous with the invert feature,
although it is unrelated. leds_toggle() is indeed supposed to toggle an LED,
while leds_invert() is supposed to change the active level of an LED. However,
all users of leds_invert() actually meant leds_toggle(), and the invert feature
does not make sense in this module because it is not handy due to successive
calls to leds_invert() changing the intended behavior, and hardware active
levels should be managed in leds_arch_set() (e.g. by XORing the passed value
with a hardware-specific constant before setting the output levels of the pins).
Consequently, this change:
- removes the leds_invert() function,
- makes leds_toggle() behave as expected relatively to leds_off() / leds_on(),
- sanitizes the code in the leds module.
