TIM3 is no longer used by USB CDC for triggering outgoing data, so we
can now make it available to the user.
PWM fading on LED(4) is now gone, but will be reinstated in a new way.
stmhal: Make USB CDC driver use SOF instead of TIM3 for outgoing data.2016-01-29T15:21:43+00:00Damien Georgedamien.p.george@gmail.com2016-01-09T21:59:15+00:00urn:sha1:d3631339176b768ce1ffdc535223385245ff906b
Previous to this patch the USB CDC driver used TIM3 to trigger the
sending of outgoing data over USB serial. This patch changes the
behaviour so that the USB SOF interrupt is used to trigger the processing
of the sending. This reduces latency and increases bandwidth of outgoing
data.
Thanks to Martin Fischer, aka @hoihu, for the idea and initial prototype.

stmhal: Typo fix in comment.2015-10-24T18:58:58+00:00Paul Sokolovskypfalcon@users.sourceforge.net2015-10-24T18:58:05+00:00urn:sha1:4a9c60cdfb509b61dd71dbaec36293239e6e53ccstmhal: Break immediately from USB CDC busy wait loop if IRQs disabled.2015-06-07T22:48:07+00:00Damien Georgedamien.p.george@gmail.com2015-06-07T22:48:07+00:00urn:sha1:0aa5e7500047d869cc78e8914fc08b5d6a3f5994
If IRQs are disabled then the USB CDC buffer will never be
drained/filled and the sys-tick timer will never increase, so we should
not busy wait in this case.
stmhal: Remove some unnecessary declarations, purely for cleanup.2015-03-20T22:27:34+00:00Damien Georgedamien.p.george@gmail.com2015-03-20T22:27:34+00:00urn:sha1:7674da8057b5236373345350acd2a7513377d393stmhal: Add Python-configurable USB HID mode.2015-02-13T14:02:51+00:00Damien Georgedamien.p.george@gmail.com2014-11-01T21:26:06+00:00urn:sha1:d39c7aa517b722161a7dd792fafc5096d58beec8
Different HID modes can be configured in Python. You can either use
predefined mouse or keyboard, or write your own report descriptor.
stmhal: Add USB_VCP.setinterrupt method, to disable CTRL-C.2014-11-29T15:23:21+00:00Damien Georgedamien.p.george@gmail.com2014-11-29T15:23:21+00:00urn:sha1:19fb1b4dd7173ad2cf4b2bb1b0f0c06498499bd2stmhal: Reduce coupling between USB driver and readline.2014-11-27T16:58:31+00:00Damien Georgedamien.p.george@gmail.com2014-11-27T16:58:31+00:00urn:sha1:5cbc9e0db0f01e1e643e8c091a536b54372df5bd
This makes it easier to re-use readline.c and pyexec.c from stmhal in
other ports.
stmhal: Add ioctl to USB_VCP object, so it works with select.2014-10-31T00:12:02+00:00Damien Georgedamien.p.george@gmail.com2014-10-31T00:12:02+00:00urn:sha1:9a41b32b3f58246cbe69db237877775b4d2fe920
This patch also enables non-blocking streams on stmhal port.
One can now make a USB-UART pass-through function:
def pass_through(usb, uart):
while True:
select.select([usb, uart], [], [])
if usb.any():
uart.write(usb.read(256))
if uart.any():
usb.write(uart.read(256))
pass_through(pyb.USB_VCP(), pyb.UART(1, 9600))
stmhal: Improve REPL control codes; improve pyboard.py script.2014-10-26T15:39:22+00:00Damien Georgedamien.p.george@gmail.com2014-10-26T15:39:22+00:00urn:sha1:bc1488a05f509cd5be8bfab9574babfcb993806f
Improvements are:
2 ctrl-C's are now needed to truly kill running script on pyboard, so
make CDC interface allow multiple ctrl-C's through at once (ie sending
b'\x03\x03' to pyboard now counts as 2 ctrl-C's).
ctrl-C in friendly-repl can now stop multi-line input.
In raw-repl mode, use ctrl-D to indicate end of running script, and also
end of any error message. Thus, output of raw-repl is always at least 2
ctrl-D's and it's much easier to parse.
pyboard.py is now a bit faster, handles exceptions from pyboard better
(prints them and exits with exit code 1), prints out the pyboard output
while the script is running (instead of waiting till the end), and
allows to follow the output of a previous script when run with no
arguments.
