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: 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 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: Add USB_VCP class/object, for direct USB VCP control.2014-07-31T09:30:42+00:00Damien Georgedamien.p.george@gmail.com2014-07-31T09:30:42+00:00urn:sha1:3c4db9f91c01211aed47afe3efdd11477badc0bc
Before, pyb.stdin/pyb.stdout allowed some kind of access to the USB VCP
device, but it was basic access.
This patch adds a proper USB_VCP class and object with much more control
over the USB VCP device. Create an object with pyb.USB_VCP(), then use
this object as if it were a UART object. It has send, recv, read,
write, and other methods. send and recv allow a timeout to be specified.
Addresses issue 774.
Add license header to (almost) all files.2014-05-03T22:27:38+00:00Damien Georgedamien.p.george@gmail.com2014-05-03T22:27:38+00:00urn:sha1:04b9147e150d2d6fa3750f312fe328b6a71c1b28
Blanket wide to all .c and .h files. Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.
Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
stmhal: Add timer module; move servo PWM from TIM2 to TIM5.2014-04-02T14:09:36+00:00Damien Georgedamien.p.george@gmail.com2014-04-02T14:09:36+00:00urn:sha1:a12be917a4644305e7813b3f4b11880aba3632ca
As per issue #257, servo is better on TIM5 because TIM2 is connected to
more GPIO.
stmhal: Add intensity method for blue LED.2014-03-22T23:54:13+00:00Damien Georgedamien.p.george@gmail.com2014-03-22T23:54:13+00:00urn:sha1:908a670dfc44111c1c1f3fdee0ebb7471c2ef079
As part of this, rejig the way TIM3 is initialised, since it's now
shared by USB CDC and the blue LED PWM.
