Status:
|
|
- = Planned.
|
|
X = In progress, some work done.
|
|
* = Done.
|
|
? = Not sure if worth the effort or useful at all.
|
|
N = Decided against.
|
|
|
|
Current Pipeline (2.3.x):
|
|
* Improved Makefile system.
|
|
* USB driver enhancements.
|
|
* USB and USB_SERIAL APIs reclassification.
|
|
* Incorporate the USB bus attach/detach handling in usbStart()/usbStop().
|
|
* Fix zero size packets handling in USB_SERIAL driver.
|
|
? USB double buffering support for STM32 implementation.
|
|
X Evaluate using DMA channels for buffer copy.
|
|
X I2C device driver class support and at least one implementation.
|
|
X Evaluate a modified I2C API where the synchronous mode is default and the
|
|
callback mode optional.
|
|
- Software I2C implementation using a GPT instance for timings.
|
|
* STM32F2xx/STM32F4xx support (adapt and re-verify all drivers).
|
|
* New STM32 DMA helper driver abstracting differences between
|
|
STM32F2xx/STM32F4xx and other sub-families.
|
|
* Specific ADC driver for STM32F2xx/STM32F4xx.
|
|
- MMC_SPI driver revision and speedup.
|
|
- FatFs 0.9x integration.
|
|
- FPU support in CM4 port.
|
|
- Nios II support.
|
|
- LPC17xx support.
|
|
- Static memory allocation hook macros in kernel code.
|
|
? Revision of scheduling strategy for threads at equal priority.
|
|
|
|
Within 2.x.x
|
|
X File System infrastructure.
|
|
X Implement the "transmission end" serial driver event on those platforms
|
|
supporting the feature, so far only done in STM32 driver.
|
|
- Add a CH_THREAD macro for threads declaration in order to hide
|
|
compiler-specific optimizations for thread functions. All demos will have
|
|
to be updated.
|
|
- Test suite overhaul, the API should be more generic in order to be used
|
|
with different subsystems and not just the kernel.
|
|
- Reduce number of demos globally, add demos to a repository or on web site.
|
|
Required in order to reduce support effort.
|
|
- MAC driver for STM32F107.
|
|
- FatFs wrapper.
|
|
- New device driver models: Clock, Systick, RTC, WDG, DAC, Power Monitor.
|
|
- Add UART4 support to the STM32 UART driver (CL line only, HD has a nasty
|
|
shared interrupt).
|
|
- STM32 OTG USB cell support for CL devices.
|
|
- Add ADC3 support to the STM32 ADC driver.
|
|
- Shared DMA channels support in the STM8L HAL.
|
|
- Device drivers for STM8/STM8L (ADC, PWM, bring them on par with STM32).
|
|
- Device drivers for LPC1xxx (ADC, PWM, bring them on par with STM32).
|
|
- Implement USB Mass Storage Class support and demo using the MMC_SPI driver
|
|
as back-end.
|
|
- Batch testing of the ARM7/ARMCMx port using OpenOCD, with reports.
|
|
X Transactional flash file system implementation.
|
|
- Serial over UART complex driver driver, evaluate from the performance
|
|
results if to make obsolete the current dedicated Serial driver.
|
|
- Official segmented interrupts support and abstraction in CMx port.
|
|
- MAC driver revision in order to support copy-less operations, this will
|
|
require changes to lwIP or a new TCP/IP stack however.
|
|
- Update C++ wrapper (Heap, Pools, Mailboxes and any new feature).
|
|
- Threads Pools manager in the library.
|
|
- Dedicated TCP/IP stack.
|
|
? Evaluate if change thread functions to return void is worthwhile.
|
|
? Add a *very simple* ADC API for single one shot sampling (implement it as
|
|
an injected conversion on the STM32).
|
|
? Add a switch to enable/disable the priority inheritance algorithm in mutexes.
|
|
? ISO7816 driver over UART driver, both reader and card side.
|
|
? Merge the Coldfire branch in mainline (hardware missing).
|
|
? Merge the H8S branch in mainline (hardware missing).
|
|
|
|
Ideas for 3.x.x:
|
|
- MMU/MPU support.
|
|
- High resolution timers and tickless kernel.
|
|
- Multicore support.
|
|
|
|
Side projects:
|
|
X ChibiOS Wizard, UML modeling and ChibiOS applications code and
|
|
documentation generator.
|
|
- Visual debugger/monitor interfaced through OpenOCD.
