* UART9 was supported as LPUART on some H7s.
* Newer 100-pin H7 CPUs support UART9 and USART10.
* 100+ pin devices support higher numbered UARTS than UART10.
Use USE_LPUART instead of hacking into UART9 for clarity.
* LPUARTS are different from other types of UARTS.
* They need different ID ranges.
* They have and different capabilities.
* Renumber LPUART1 to 40.
0-19 reserved for UART1-20
40-49 onwards for LPUART instances.
It makes sense to treat them as a different class of UART. Just like we
do for softserial, vcp, etc.
- Add displayWriteFontCharacter() for font writing, removing all max7456
specific code.
- Add displayIsReady() for asynchronous display initialization
- Add displayBeginTransaction()/displayCommitTransaction() for display
transactions, which allow performing complex drawing operations without
flickering
- Add displayGetCanvas(), which retrieves the canvas associated with a
display (if it has it)
- Add canvas implementation for pixel based access for a display
- Add FrSkyOSD driver and displayPort driver
- Enable FrSkyOSD driver for targets with flash > 256
- Rename max7456_symbols.h to osd_symbols.h
Will hopefully reduce the number of cases where users incorrectly disable MSP on the VCP port and then can no longer connect.
Should be supplemented with changes to the configurator that prevents turning off MSP on the VCP port.
* Support DTR in serial passthrough mode to enable programming of Arduino
based devices such as MinimOSD.
Use 'serialpassthrough 5 57600 rxtx 56' and then use Ardino to program MinimOSD
Use 'serialpassthrough 5 115200' and then use MWOSD configurator to setup
* Fix comment for CDC_SetCtrlLineStateCb routine
* Handle F7 CDC interface
* Use strToPin() to allow easy port/pin specification
* Fix use of CDC_SetCtrlLineStateCb for all processor types
* Only set baud when specified
* Fix unit tests for cli
* Only register callback if needed
* Fix white space
* Provide implementation of IOConfigGPIO in SITL
* Update serialpassthrough help text
* DTR handling through serial drivers
* Fix F3, F7 and SITL builds
* If serialpassthrough command specifies baud rate of 0, set baud rate over USB. MWOSD configurator can now access config and reflash MinimOSD without rebooting and changing baud rate.
* Fix F3 build
* Fix failing unit tests
* Use resources to declare DTR pin assignment
* Don't assert DTR during normal operation as MW_OSD doesn't like it
* MW_OSD must be built with MAX_SOFTRESET defined in order to support DTR resets
* Minimise changes after dropping DTR pin param from serialpassthrough cmd
* Remove DTR pin param from serialpassthrough cmd
* Treat ioDtrTag as boolean in conditional statements
* Tidy buffer check
* Check buffer size in CDC_Itf_Control
* Fix unit test
* Add documentation for DTR
* Add note on MAX_SOFTRESET to documentation
* Remove superfluous function definitions
* Fix tabs
* Fix tabs
* Removed superfluous entried from vtable
* Backout whitespace changes unrelated to this PR
* Pass true/false to IOWrite()
* Fix line coding packing
* Add LINE_CODING structure defintion
* Revise serial documentation
* Prevent tx buffer overflow in serialPassthrough()
* Revert change unrelated to PR
* Review feedback from ledvinap
* Fix unit test
* Use PINIO to drive DTR
* Fix unit test
* Remove change unrelated to PR
* Fix SITL build
* Use shifted bits for mask definition
* Fix serialpassthrough documentation
* Only compile PINIO functionality if USE_PINIO defined
* IOConfigGPIO not needed
* Move cbCtrlLine callback to cli.c
* serialPassthrough params changed
* Check packed structure size
* Fix unit test
* Tidy up baud rate handling
