Status:
- = Planned.
X = In progress, some work done.
* = Done.
? = Not sure if worth the effort or useful at all.
N = Decided against.
Within 2.3.x (hopefully)
* Add an USB abstract device driver class.
* USB driver implementation for STM32F102/STM32F103.
* Add a Serial over USB generic device driver implementing a USB Communication
Device Class and offering a Serial-like interface to the applications.
* Add I-class APIs for mailboxes.
* Modify chEvtBroadcast() to accept a flags mask as parameter.
* Add a "transmission end" event to the serial device driver model.
X Implement the "transmission end" serial driver event on those platforms
supporting the feature.
* Swap TIME_IMMEDIATE and TIME_INFINITE values.
* Improvements to the message passing mechanism in order to allow "delayed,
out of order, responses".
* New device driver models: GPT, ICU.
X GPT implementation and long duration "IRQ storm" stress test applications
for all the supported critical platforms.
X Introduce compiler-info macros to the port layer, improve the test reports
with the compiler info.
- Add UART4 support to the STM32 UART driver (CL line only, HD has a nasty
shared interrupt).
- Add ADC3 support to the STM32 ADC driver.
? Make thread functions return void and add a CH_THREAD macro for threads
declaration in order to hide compiler-specific optimizations for thread
functions.
- Test suite overhaul, the API should be more generic in order to be used
with different subsystems and not just the kernel.
- 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.
X File System infrastructure.
- Official FatFs wrapper using the new infrastructure, dedicated test suite.
X Transactional flash file system implementation.
X I2C device driver class support and at least one implementation.
X Shared DMA channels support in the STM32/STM8L HALs.
? RAM ISR vectors support in the STM32 HAL.
- New device driver models: Clock, Systick, RTC, WDG, DAC, Power Monitor.
Later but within 2.x.x
- Batch testing of the ARM7/ARMCMx port using OpenOCD, with reports.
- Debug-related features and tools.
? Add a *very simple* ADC API for single one shot sampling (implement it as
an injected conversion on the STM32).
- Improved Makefile system.
- Serial over UART complex driver driver, evaluate from the performance
results if to make obsolete the current dedicated Serial driver.
- LPC17xx family support.
- Official segmented interrupts support and abstraction in CMx port.
- USB driver implementation for STM32F105/STM32F107.
- MAC driver revision in order to support copy-less operations, this will
require changes to lwIP or a new TCP/IP stack however.
- MAC driver for STM32F107 (hardware missing).
- Update C++ wrapper (Heap, Pools, Mailboxes and any new feature).
- Threads Pools manager in the library.
- Add a switch to enable/disable the priority inheritance algorithm in mutexes.
- Dedicated TCP/IP stack.
? ISO7816 driver over UART driver, both reader and card side (hardware
missing).
- 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.
