Updated some of the init code for the CP210x.
Before it worked with the one USB to serial adapter I had, but
we foudn it id did not work with Adafruit USB adaptor nor with their metro boards
The first gigabyte fix, was to always force the keyboard into boot protocol mode, which appeared to work well for all of the keyboards I tried.
Unforationally it caused issues with some wireless keyboard/mouse combo packages, including some logitech and some microsoft keyboards.
This version instead, I created a list (currently only one vendor id), of vendor id:product id, that need to be forced into boot mode. Knowing that if there is one keyboard vendor with this N key rollover feature, there are probably others. So while this list can be expanded, this requires users to update library. So added a method forceBootProtocol method to keyboard class that allows the user to try it out without needing to update the library sources.
The mouse test program has example of either setting it before the keyboard is initiated, as well as another way that when a connection is found it asks for the vendor id, and if it is the one of my gigabyte keyboard, it calls the function then.
While doing this I found some of the query functions like idVendor on the keyboard class would not compile as the keyboard object has multiple inheritence and both base classes have this. So like the joystick objects I added these to the top level function and these functions will direct the calls to the approrpriate places.
The gigabyte keyboard has an N key rollover input, that is different than all of our current keyboards.
So this code tells (currently All) keyboards to choose their boot protocol, which gets us back to the standard boot definition. Which alllows these keyboards to function like others.
Support for using the Microsoft XBox 360 wireless receiver for windows
to be able to communicate with XBox 360 wireless controllers.
In theory this should support up to 4 controllers. So far I have only
tested with one as I only have one.
Added a joystick only test that should support up to 4 joystick objects.
Added support for Joysticks, that on some of them we can not receive more of the Joysticks axis. So far mainly on PS3 and PS4. So you can now get the Gyro/accel stuff. You get feedback on the DS4 touch area, PS3 you can get the pressure values on several of the buttons. LIke the RT/LT ones.
In addition added some support for Rumble. So far it appears to be working somewhat on the PS3 and PS4 controllers. On the PS4 you can also set the RGB LED light values and on the PS3 you can set the 4 LEDS on the front., which are normally used to say which controller it is.
While the other Joystick objects currently supported by the USB Host
code are driven by HID data, the Xbox does not contain HID data and
instead works at the top level.
To handle this I made the Joystick object use multiple InHeritence like:
class JoystickController : public USBDriver, public USBHIDInput
This allowed me to have the object work either way. This did add some
complexity in that some of the methods like is the object connected
(The bool operator) had to be overwritten as both of the bases classes
had it. In addition needed to update the other query functions to be
able to grab the data from mydevice or device depending on which type of
controller was connected.
Since this looked like a valid way, I then merged the Keyboard Extras
code that Keyboard and made it also do a similar multiple inheritance.
In this case however I restricted the HID top level report handle code
to only accept it if on the same object that claimed the keyboard.
The mouse test app was updated as well
Needed HID Parser to support Bidirectional Transfers
The HidParser code was setup such that the claim for a report, the caller could say I want to claim the whole thinig and allowed callback functions for processing of in buffer and out buffer.
Allow RawHID to contribute Transfer_t
Since RawHID may need more resources than most, maybe it should contribute the additional structures
The constructor for a RAWHID object allows you to specify the top usage
that it wishes to connect to. I used this for example to be able to
connect to a Teensy with the RAWHID associated with emulating the
Serial object.
If a HID Input class says that it wants to claim the whole interface, I
reuse the buffer associated with holding the HID descriptor and use it
for output buffers.
I am not sure if you can also get the same hang in the periodic update list as well, but to be on the safe side added same checks as the one that was hanging.
Found the issue where it was freeing transfers from the follow up list, that were also on the QH list which also tried to free it again.
Fix was in the first free list, it checks to see if the item is also in the qh list and does not free it then.
As per the forum posts, worked on combining the claim code for extracting which endpoints are RX and TX and create the pipes and the like.
Also worked on live cases. Reading and writing to AX servos... Found some issues Probably more to find.
I left in some debug code to help find cases of deleting a pipe may hang. Also macros in serial.cpp to set or toggle IO pins (when in debug mode). This helps find where things are happing using Logic Analyzer as a way to find the approriate USB packets.
The main issue was I used a setup structure on the stack which turned into garbage. Earlier I thought the data was copied, but it was not...
Found that fixing this resolved the earlier issue where I needed to defer the update. So removed the defered code, plus use member variable for the one byte output instead of static variable.
I did a quick test using the Serial test app, where I can type in lines like:
#38400,7E1
And it reopens the serial port at the specified baud and format. Note the formats the test app looks for is 7E1, 7O1, 8N1, 8N2.
Tested on an FTDI, PL2303 and CH341. I also tested going to Teensy 3.2 CDCACM. But as far as I know the teensy could not care less about Baud/Format.
Unless of course there is a way to query the value and use it to set a Hardware Serial port to it.
This commit adds support for at least some of the Serial boards with the
CH341 chipset, tested using a board from sparkfun as well as one from
Amazon.com
The code was rearranged some of the Claim code and added a VID:DID to Serial Type table that I use to map, such that I know some of these devices have multiple valid setups.
Support Begin/End/Begin - Change baud
Added code to support switching baud rates, or more particular be able to call end() and then call begin(...) with same or different baud rate.
Hopefully some support for also releasing DTR when the end is called.
WIP - Start support for the begin(baud, format)
Adding some support to the code to handle some of the different possible format capabilities.
In particualar trying to handle the parity, number of bits and number of stop bits.
hacked up test app, such that if you type in command line like:
"#9600, 7e1"
It will extract the 9600 as the new baud and try to use format 7e1. I only hard coded a few of these in the test app (8n1, 7e1, 7e2, 8n2)...
Again work in progress. Took me awhile tofigure out how to do this for ch341 boards as I did not see any documents or code that handled this. So had to deduce it from differences in USB packets.
Added support for a another Serial type CH341.
Wip - But I do have it working so far at least with a loop back test (RX shorted to TX)
Also Rearranged some of the Claim code and added a VID:DID to Serial Type table that I use to map, such that I know some of these devices have multiple valid setups.
Will test more. I have several more cheap USB to serial adapter arriving tomorrow.
