This release covers everything from 2021-10-01 and has been tested with avr-gcc
v10.2.0 from Upstream and arm-none-eabi-gcc 10.3-2021.10 from Arm.

Breaking changes:

  • modm:driver:encoder_input.bitbang has changed its API.
  • modm::Saturated class has been completely refactored.

Features:

  • STM32F1 internal flash driver.
  • Use FreeRTOS with static memory by default.
  • SAMG UART driver.
  • SAMG ADC driver.
  • STM32F4 Ethernet support via FreeRTOS+TCP.
  • STM32F4 and STM32F7 DMA support.
  • VSCode IDE support via modm:ide:vscode.
  • Experimental support for fibers.
  • Vector table remap into SRAM on Cortex-M0+ and STM32F0.
  • STM32H7 DMA driver.

Integrated Projects:

  • ETL added at v20.22.0.
  • TinyUSB upgraded to v0.12.0.
  • FreeRTOS upgraded to 202112.00.
  • LVGL upgraded to v8.1.0.

Fixes:

  • Remove heap dependency for static virtual destructors.
  • Correct STM32G4/L4+ voltage scaling and boost mode.
  • Move main stack to DMA-able memory for STM32F4.
  • Linkerscript alignment issues for copy sections.
  • Zero SRAM after uploading to prevent false positive RTT identifier.
  • Off-by-One error in EXTI IRQ handler.
  • DMA data fixes for STM32G0, L4, H7 and WL.
  • Do not reset STM32 Advanced Timer RCR during configuration.

New development boards:

  • NUCLEO-L053R8 as modm:board:nucleo-l053r8.

New device drivers:

  • TMP12{1,3,5} temperature sensor as modm:driver:tmp12x.
  • Encoder Input via STM32 Timer as modm:driver:encoder_input.
  • MCP7941X RTC driver with EUI-48/64 and EEPROM as modm:driver:mcp7941x.
  • ADS816X ADC driver as modm:driver:ads816x.

Known bugs:

  • Cannot set breakpoints on specific lines in debug profile. See #777.
  • 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.
