* Add support for the extra 16 GPIO pins in the menus and core.
* Clean up Generic RP2350 PSRAM ("none" is valid) and flash (other than 16MB) options.
* Add extra GPIO<->peripheral connections
* Add Pimoroni PGA2350 RP2350B-based board
* Pins 32-47 can be used for PIOPrograms
* Avoid hang when PSRAM fails to initialize
* Move libpico to an RP2350B board for SDK (otherwise the SDK drops all GPIOHI support)
* Update to 2.0.0 SDK
* Board type needs to be set before earliest SDK setup
* Platform includes update
* Boot2 files
* Simple compilation issues
* Build and link
* PIO rebuild with version
* Newlib wrapper update
* Force inclusion of runtime_init_* fcns
The linker was dropping all references to the library's included
runtime_init_xxx functions and hence things like the IRQ vector
table and mutexes and alarms weren't properly set up leading to
instant crashes on start up..
Explicitly call out one function from the object file stored in
the .A to force the inclusion of all the functions. May be a better
way, heppy to hear any ideas.
* Fix SPI GPIO calls
* Fix Ethernet GPIO
* Remove SDK warnings
Remove the skipped error messages once the following PR merged:
https://github.com/raspberrypi/pico-sdk/pull/1786
* BTStack moved SBC encode/decode paths
* Platform.IO fixes
* BT No longer has special absolute mouse
* Rebuild and update OTA
* Rebuild BearSSL, too
* Update liker file to latest SDK
* Clean up libpicocmake
* Clean up LWIP/BT library names
Fixes#1192
Uses DMA operations to avoid the need to bit-bang or busy wait for SPI
operations that might be very slow. Optional, adds new API calls to enable.
Simple example included.
With HW chip select enabled, transfer16's 2 individual byte transfers will
actualy deassert CS for a brief instant between bytes. Avoid this by doing
a single multi-byte (2) tranfer of 16b.
It would be possible for an IRQ-driven SPI user to fire
while the main app's SPI.beginTransaction was in process.
This would result in incorrect state for the main app since
the IRQ may overwrite some settings that the app already
set.
Disable all IRQs around the begin and end processes to avoid
the possibility.
Fixes#1147
When SPI.beginTransaction() is called, disable all GPIO IRQs that were
registered using SPI.usingInterrupt(). On SPI.endTransaction(), restore
all the IRQs to their prior state.
Add plumbing to allow `Wire`, `Serial1`, `SPI1` to map to the 2nd
hardware unit for devices where the PCB layout only brings out the
2nd port.
Fix the Seeedstudio XAIO pins
Fixes#594
Leave the SPI port initted after a transaction, and when a new one comes in
check if it is the same settings we're already running. If so, do nothing.
If not, deinit and reinit. In general the settings will be identical, so
this will speed things up massively.
Fixes#392
Fixes#169
Trying to change pinout while running, or to an illegal configuration,
will now immediately panic() with an error message. Such an attempt
is a pretty big problem since pinouts are hardware related/static.
Prior code would fail silently and return false, but nobody checked
the setXXX return values, anyway.
Fixes#167
For Serial when selecting TinyUSB. Can't include in the core because Arduino IDE
will not link in libraries called from the core. Instead, add the header to all
the standard libraries in the hope it will still catch some user cases where they
use these libraries.
See https://github.com/earlephilhower/arduino-pico/issues/167#issuecomment-848622174
Use a constexpr template to calculate the valid pins for different IO
hardware. This lets us have an easily readable list of pin numbers that
we can adjust/check.
