Update to head of upstream FreeRTOS/SMP branch. Very minor changes.
Remove the custom getreent implementation, use the one that was defined
in the upstream FreeRTOS/smp branch (callback related vs. static vars).
Fixes#1439
Use a real FreeRTOS task, at the highest priority, to idle the other core
while doing flash accesses.
The USB stack seems to have some timing dependent bits which get broken
if FreeRTOS switches out the current task when it's running. Avoid any
issue by disabling preemption on the core for all tud_task calls.
The PendSV handler disable flag can live completely inside the FreeRTOS
variant port, so remove any reference to it in the main core.
Tested using Multicode-FreeRTOS, #1402 and #1441
The USB FIFO interrupts were still being serviced even when the core was
frozen, leading to crashes. Explicitly shut off IRQs on both the victim
and the initiator core when freezing.
Removed the need for hack __holdUpPendSV flag
Fixes#1408
The wl_* types are required in multiple libraries which in turn seem
to have a circular dependency that Platform.IO has issues with in certain
modes.
Avoid the issue by moving the common headers into the core directories
so they will be accessible by all libs.
Move StackThunk to core directory, too
Fixes#1402
The global USB mutex is auto-shadowed with a FreeRTOS semaphore while in
FreeRTOS mode. Unfortunately, while the core was using the proper
FreeRTOS semaphore to lock access to the USB port, the actual FreeRTOS
USB task was using the naked Pico SDK mutex, leading to cases where it
could acquire the mutex even though some other FreeRTOS task actually
owned the shadowed mutex.
Properly lock the shadowed Semaphore, not mutex_t, in the FreeRTOS
USB periodic task.
Fixes#1370
Adds a simple helper assertion to tell the user how to enable BT if it's
not enabled, instead of some odd compilation warnings about undefined
functions.
Fixes#1356
Mac and Windows have case-insensitive filesystems, so the will find
the internal (all-lowercase) "btstack.h" and not the library's "BTstack.h",
causing compilation errors.
Rename the library and header to avoid the issue.
Allow sending thigns like KEY_MUTE or KEY_SCAN_NEXT from the USB and
Bluetooth Classic keyboard libraries.
BLE requires some add'l magic, not yet discovered.
Pull in latest upstream Keyboard library changes
SDK 1.5 changed the behavior of the underlying CYW43 blob, and it seems
to block MDNS multicast by default. Manually add back the Ethernet MACs
used for MDNS multicast in IPV4 and IPV6.
Fixes#1267
It seems possible now for TCP connection _pcbs to disappear while being
processed, due to the new async context configuration. This would cause
LWIP to panic when a NULL pcb was passed in.
Check for and avoid passing in null PCBs in the ClientContext.
Undo special-casing of sys_check_timeouts wrapper
AdvancedWebServer with heavy F5-refresh and #1274 test both pass.
Fixes#1274
Move the Joystick, Keyboard, and Mouse into a base class which handles
the operation/input, and a subclass which will implement the reporting
as a HID device via USB, Bluetooth Classic, or Bluetooth Low Energy (BLE).
Reduce copies of library code and makes maintainability much better.
* Update to Pico-SDK v1.5
* Hook in pico_rand, use ioctl to set ipv6 allmulti
* Move into PicoSDK LWIP mutex, hack timer sizes
* Utilize much of the PicoSDK infrastructure for WiFi
* Add WiFi::begin(ssid, pass, bssid)
* WiFiMulti to use BSSID, make more robust
WiFiMulti will now be more aggressive and try all matching SSIDs, in order
of RSSI, using the BSSID to identify individual APs in a mesh.
Before, if the highest RSSI AP didn't connect, it would fail immediately.
Now, it will go down the list, ordered by RSSI, to attempt to get a link.
* Add Bluetooth support from Pico-SDK
Able to build and run the HID Keyboard Demo from the Arduino IDE, almost
as-is.
Will probably need to make BT configurable. Enabling BT on a plain WiFi
sketch uses 50KB of flash and 16KB of RAM even if no BT is used.
* Separate picow libs, BT through menus, example
Build normal Pico.a and 4 different options for PicoW IP/BT configuration.
Use IP=>IP/Bluetooth menu to select between options.
* CMakefile rationalization
* Move BT TLV(pairing) out of last 2 flash sectors
The pairing keys for BT are stored at the end of flash by default, but
we use the last sector of flash for EPROM and the penultimate one for
the filesystem. Overwriting those in BT could cause some real exciting
crashes down the line.
Move the store to an app-build specific address using a dummy const
array to allocate space in the application image itself.
* PicoBluetoothHID with BT Mouse, Joystick, Keyboard
Add simple Bluetooth Classic HID helper function and port the existing
USB HID devices to it. Port their examples.
* Protect BT key storage from multicore
* Add short-n-sweet Bluetooth documents
* Add Bluetooth Serial port library
* Turn off BT when the BT libraries exit
The PWMAudio lib is expecting an int16_t value but the example passes a sample cast to uint16_t
So any values from the lookup table that are negative are recast to 0 i think.
So half the sine wave in the case of the example is lost.
Implement the method used in the ESP8266 Web Server to allow user apps to hook into
the HTTP server (to support hooked WebSockets, etc._)
Add example of hook usage
Mimics the I2S/PWMAudio/Stream interface for ease of use.
* Fix non-32b DMA size transfer calculation in ABM
* Rename wasHolding to isHolding in the I2S/PWM
It is the **current** number of bits left, not the past number.
* Add commented microphone example
* Add docs
Now that we have a default parameter, need to only allow it in C++ since
default values are not part of C spec. Should not affect any users since
only legacy code is in C.
