This release covers everything from 2021-04-01 and has been tested with avr-gcc
v10.1.0 from Upstream and arm-none-eabi-gcc 2020q4 from Arm.

Breaking changes:

  • TinyUSB updated from v0.8.0 to v0.10.1 with breaking changes to their APIs.
  • FreeRTOS configuration must be done by the user via the headers
    <FreeRTOSConfigLocal.h> and <FreeRTOSIPConfigLocal.h>.
  • modm::GraphicDisplay API changed due to change in color management.
  • New color types and API.
  • New CMake build system has different API without top-level Makefile.

Features:

  • STM32L0 support.
  • Real-Time Transport (RTT) support via OpenOCD v0.11.
  • FDCAN driver for STM32G4 (only for standard messages).
  • DMA support for all STM32 devices, except F2/F4/F7.
  • Better graphical display and color support.
  • New CMake build system for better IDE integration.
  • Top-level build scripts relicensed as BSD to allow easier adaptation.
  • LPUART driver for STM32.
  • DAC driver with DMA support for STM32.
  • Non-allocating util classes modm::inplace_any and modm::inplace_function.

Integrated Projects:

  • LVGL added at v8.0.1.
  • Petit FatFs added at v0.03a.
  • FatFs upgraded to v0.14b.
  • TinyUSB upgraded to v0.10.1.
  • FreeRTOS upgraded to 202012 LTS.

Fixes:

  • OpenOCD ITM configuration for logging.
  • Much more accurate nanosecond delay.
  • realloc with NULL pointer calls malloc when using TLSF allocator.

New development boards:

  • NUCLEO-L031K6 as modm:board:nucleo-l031k6.
  • NUCLEO-F072RB as modm:board:nucleo-f072rb.
  • NUCLEO-L496ZG-P as modm:board:nucleo-l496zg-p.
  • NUCLEO-F091RC as modm:board:nucleo-f091rc.

New device drivers:

  • SH1106 display as modm:driver:sh1106.
  • STTS22H thermometer as modm:driver:stts22h.

Known bugs:

  • C++20 is not fully implemented by GCC10 yet, however modm does not use all
    features yet anyways. See #326.
  • STM32F7: D-Cache not enabled by default. See #485.
  • lbuild build and lbuild clean do not remove all previously generated files
    when the configuration changes. See #285.
  • Generating modm on Windows creates paths with \ that are not compatible with
    Unix. See #310.
  • arm-none-eabi-gdb TUI and GDBGUI interfaces are not supported on Windows.
    See #591.

Tested by @Jasa and @salkinium.

2021-05-07: Add SH1106 display driver

PR #627 -> 7d7490d.
Tested in hardware by @TomSaw.

2021-04-22: Specialize modm::GraphicDisplay for monochrome and color

To enable optimizations for different color formats, the graphic display base
classes are refactored into monochrome and color classes.

PR #604 -> 295dbc3 with medium impact on display drivers and graphics code.
Tested in hardware by @TomSaw.

2021-04-14: Adapt DMA driver for more STM32 devices

PR #608 -> 8ca2f35.
Tested in hardware by @rleh.

2021-04-13: Add FDCAN driver for STM32G4

PR #607 -> 2d2199b.
Tested in hardware by @chris-durand.

2021-04-12: Add RTT support via OpenOCD

PR #610 -> 1375ff1.
Tested in hardware by @salkinium.

2021-04-11: Upgrade FreeRTOS to 202012 LTS

The default configuration modm provides changed, and now only provides the bare
minimum config and the remainder needs to be user-provided via the headers
<FreeRTOSConfigLocal.h> and <FreeRTOSIPConfigLocal.h>

PR #566 -> 1375ff1 with high impact on configuration management.
Tested in hardware by @salkinium.

Tested in hardware by @salkinium.

2021-04-06: Upgrade TinyUSB to v0.9.0

TinyUSB is breaking their own API quite often, so existing applications must be
adapted. Any modm wrapper APIs are unaffected. See module docs for additional
customization via the <tusb_config_local.h> header.

PR #566 -> 1f5d06e with high impact on TinyUSB API.
Tested in hardware by @salkinium.
