suspect-devices/circuitpython/stmhal/usbd_cdc_interface.c, branch 5.3.x CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=5.3.x 2017-09-06T03:40:51+00:00 ports: Make new ports/ sub-directory and move all ports there. 2017-09-06T03:40:51+00:00 Damien George damien.p.george@gmail.com 2017-09-06T03:40:51+00:00 urn:sha1:01dd7804b87d60b2deab16712eccb3b97351a9b7 This is to keep the top-level directory clean, to make it clear what is core and what is a port, and to allow the repository to grow with new ports in a sustainable way. stmhal: Clean up USB CDC/MSC files and remove commented-out code. 2017-07-19T03:01:22+00:00 Damien George damien.p.george@gmail.com 2017-07-19T03:01:22+00:00 urn:sha1:c972c60dbe72d7448faff7f631dfb798b694093e stmhal/usb: Use local USB handler variable in Start-of-Frame handler. 2017-06-07T06:03:19+00:00 Sylvain Pelissier sylvain.pelissier@gmail.com 2017-05-04T07:39:08+00:00 urn:sha1:3bb69f645a29429be63756616d3019e889c1d355 stmhal: Pass USB handler as parameter to allow more than one USB handler 2017-06-07T05:50:26+00:00 Sylvain Pelissier sylvain.pelissier@gmail.com 2017-05-03T08:55:02+00:00 urn:sha1:6adcf7bb8288fb6fd0e131f081735dd5cff16b86 stmhal/usbd_cdc_interface: Change CDC RX to use a circular buffer. 2017-04-04T06:23:25+00:00 Damien George damien.p.george@gmail.com 2017-04-04T06:23:25+00:00 urn:sha1:3b447ede78970df04e08eeb1cc549a574a733667 This should be a little more efficient (since we anyway scan the input packet for the interrupt char), and it should also fix any non-atomic read issues with the buffer state being changed during an interrupt. Throughput tests show that RX rate is unchanged by this patch. stmhal/usbd_cdc_interface: Increase in-endpoint timeout to 500ms. 2017-04-04T05:18:58+00:00 Damien George damien.p.george@gmail.com 2017-04-04T05:18:58+00:00 urn:sha1:9a8e7f7a8e93e9319d2ff5795f4b8a6b9e4ba5ad The previous timeout value of 150ms could lead to data being lost (ie never received by the host) in some rare cases, eg when the host is under load. A value of 500ms is quite conservative and allows the host plenty of time to read our data. stmhal: Use generic interrupt char code. 2017-02-15T05:39:30+00:00 Damien George damien.p.george@gmail.com 2017-02-15T05:39:30+00:00 urn:sha1:e5cc681cb1b5163b9ae3453df85344326baf9759 stmhal: Use core-provided keyboard exception object. 2016-12-15T04:51:34+00:00 Damien George damien.p.george@gmail.com 2016-12-15T04:51:34+00:00 urn:sha1:a770ba147edfab6cf060147f6ef47cf19c1c332b stmhal/usb: Always use the mp_kbd_exception object for VCP interrupt. 2016-12-15T01:45:56+00:00 Damien George damien.p.george@gmail.com 2016-12-15T01:45:56+00:00 urn:sha1:979ab4e126dacca4d7fbbd0e71c849365ef2c947 There's no need to store a separate pointer to this object. stmhal: Make TIM3 available for use by the user. 2016-01-29T22:31:56+00:00 Damien George damien.p.george@gmail.com 2016-01-29T22:31:56+00:00 urn:sha1:ea89b80ff4f842b010f9f8ec3280675f81bc6bc5 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.
