  1. CoRTOS is a Cooperative Real Time Operating System for bare-metal applications. Its advantages over other systems are that it is fully documented with a manual and examples, is easy to understand and use and is astonishingly simple: The kernel is just 16 lines of C. The CoRTOS module compiles to ~200 bytes of code. The system includes optional modules implementing delays, timers, messaging, mutexes and signaling. It is intended for smaller microprocessors, such as the MSP430, Cortex M0+, AVR and PIC24, and for smaller systems of maybe a dozen tasks. CoRTOS is not a task sched
  2. Announcing the release PRTOS, an open-source preemptive real time operating system kernel for bare-metal applications. You may find PRTOS a good choice if you want to learn about preemptive multitasking. The API, though having all the features of FreeRTOS or uC/OS, is much simpler and easier to learn. Additionally the system will fit into much smaller processors. PRTOS is released by Cleveland Engineering Design - the developer of the CoRTOS cooperative real time OS, also available on Sourceforge. PRTOS presently supports the MSP430 and AVR architectures. PRTOS is availab
  3. The open-source RTOS called "NUFR" has been ported to the MSP430/MSP430X CPUs. NUFR is a full featured RTOS--not just a simple scheduler. Features: MSP430 and MSP430X 16- and 20-bit models Make system included; all free/open-source tools Prioritized & Preemptive multitasking; Round-Robin multitasking; context switching from interrupt handlers Low-power extensions: tickless OS; special logic for low power mode RNET IPv4/IPv6/UDP stack runs on NUFR Message-based, event-driven Example project for Launchpad board Small RAM footprint: OS itself co
  4. I created an open-source RTOS called "NUFR" and I'm wanting to port it to the MSP430. So, first I'm advertising NUFR and second I'm soliciting advice for the port. NUFR is a small but nevertheless full-featured RTOS. It is ideal for the 430, that's why I'm porting it there. It already runs on the Cortex M's. Here's some approximate resource consumption numbers on the M3 /M4: - the NUFR kernel and services layers consume around 4-6k of flash. Basically, that's all the features turned on. - RAM consumption: Around 300 bytes of kernel and messaging overhead; Add for each task: TCB
  5. I'm exploring TI-RTOS and developing easy-to-use libraries for Energia MT. The idea is to encapsulate each RTOS element into a class. Up to now, I've implemented the following libraries: Event library with choice of event number Event_Id_00 ... Event_Id_31 Semaphore library Mailbox library Timer library
  6. There is an edX course coming up in September from the University of Texas in Austin - this time with MSP432 or TM4C123 LaunchPad. The parts list also includes the CC2650 and Educational BoosterPack MK-II. The syllabus includes BLE and RTOS. It is taught by Jonathan Valvano and Ramesh Yerraballi who have offered a course using the TM4C123 on edX in the past. https://www.edx.org/course/real-time-bluetooth-networks-shape-world-utaustinx-ut-rtbn-12-01x http://edx-org-utaustinx.s3.amazonaws.com/UT601x/RTOS.html edit: forgot to mention that these courses are free if you just audit th
  7. I posted a blog entry about how I used the STM32L1 RTC (a few years ago) as a tickless, ultra-low-power timer for my RTOS. http://www.indigresso.com/_blog/?p=181 The MSP432 has a similar problem. Only the RTC and Watchdogs run in LPM3 and 3.5, no other timers do, but you want to use those LPMs for timed sleep! There is a workaround, and it is actually very fast thanks to the really great ALU in the CM3 and CM4 devices. My code is also implemented in bulletproof production firmware that I've shipped to various industries . Yes, the code is for STM32L1, but I think you should be able
  8. Hi, Is it possible to use Energia via command-line (like a makefile)? I found such a makefile [1], but it supports only msp430. [1] https://github.com/elpaso/energia-makefile Thanks
  9. Hello, I want to design and make Cubesat OBC(On board computer) using MSP 432 & energia for eash coding and RTOS. But i am student and begginer. if i design like schematic for MSP432-Lunchpad, could i use energia without any other processes? if not, How can i use energia for my DIY board? and I want to connect SRAM to MSP432 using SPI communcation and control SPI using energia is it possible? Could i use fully functionality of RTOS using energia ? and if you any other advice, please let me know. I'd appreciated if you reply these questions. Thank you much.
