Without this the timer will have random values for its State and Lock
entries. The object can then be in a locked state leading to some HAL
functions returning immediately with an error code (which is unchecked).
This patch fixes such a bug which did manifest itself as PWM not working
correctly for LEDs.
This check always fails (ie chr0 is never EOF) because the callers of this
function never call it past the end of the input stream. And even if they
did it would be harmless because 1) reader.readbyte must continue to
return an EOF char if the stream is exhausted; 2) next_char would just
count the subsequent EOF's as characters worth 1 column.
import utimeq, utime
# Max queue size, the queue allocated statically on creation
q = utimeq.utimeq(10)
q.push(utime.ticks_ms(), data1, data2)
res = [0, 0, 0]
# Items in res are filled up with results
q.pop(res)
This is required to avoid extra level of output "cooking" ("\r\r\n") and
make test infrastructure work. On the other hand, this breaks somewhat
Zephyr console abstraction.
Defining and initialising mp_kbd_exception is boiler-plate code and so the
core runtime can provide it, instead of each port needing to do it
themselves.
The exception object is placed in the VM state rather than on the heap.
mp_kbd_exception is now considered the standard variable name to hold the
singleton KeyboardInterrupt exception.
This patch also moves the creation of this object from pyb_usb_init() to
main().
Previous to this patch pyboard.py would open a new serial connection to
the target for each script that was run, and for any command that was run.
Apart from being inefficient, this meant that the board was soft-reset
between scripts/commands, which precludes scripts from accessing variables
set in a previous one.
This patch changes the behaviour of pyboard.py so that the connection to
the target is created only once, and it's not reset between scripts or any
command that is sent with the -c option.
When printing exceptions from files sent to a target by pyboard.py the
filename in the exception is <stdin>, which differs to when running the
script on the PC. So we strip out the filename to make the outputs the
same on all targets (see also misc/print_exception.py test).
