Description:

Description

The STM32-Primer embeds the CircleOS operating system. It provides services that will help you develop your STM32-Primer applications:

  • Application management,
  • LCD graphic functions,
  • Mems functions,
  • LED,
  • Buzzer and Push Button functions,
  • Menu functions,
  • Scheduler task,
  • ...

The small footprint of CircleOS (only 22/128 KB) allows you to keep up to 104/384 KB for the applications. The list of the available applications is stored in a table (FAT) at the top of the memory used by CircleOS. 

Each application is run by CircleOS when selected, has the full availability of the CPU and can use the entire RAM which is not used by CircleOS. It will be scheduled by the CircleOS with full privileges on the device, until it explicitly quits.

Installation

Unzip in the directory "[Ride7_INSTALL_DIR]\Lib\ARM"

Upgrade

The CircleOS upgrade files are available for Primer's and Evo Primer's as a download in Primer_upgrade.zip, Primer2_upgrade.zip, EvoPrimerSTM32E_upgrade.zip, EvoPrimerSTM32C_upgrade.zip, EvoPrimerSTM3240G_upgrade.zip, and  EvoPrimerSTM32G_upgrade.zip

 

Documentation

The Doxygen CircleOS documentation is available online or as a download in this ZIP file
Moreover, a work document describes the internal conception of CircleOS and the use of the API's    .
