How to lower CPU usage in a very tight loop without sleep?
I'm writing a small program that use libmodbus to communicate with other devices. And it seems that modbus protocol only has the concept of request-reply so only way I can do to get the data is to pull it with modbus_read_registers in a loop. Something like this:
- Libmodbus – A modbus library for Linux, Mac OS, FreeBSD and windows
- Libmodbus - A modbus library for linux, mac os, freebsd and windows
-
which modbus c library do you use?
> thanks, but these are for linux based drivers. Yes, libmodbus is for "big" OS but as described in the article and pointed in its README on github (https://github.com/stephane/libmodbus/) You can run it on MCUs with Embox RTOS.

Release v0.5.9.10 · embox/embox
Embox is a configurable RTOS designed for resource constrained and embedded systems. Embox main idea is using Linux software without Linux. (https://embox.github.io/ ) If you want use complex Linux Software and Linux is huge for your goals. Embox is the best idea, as I think. For example Embox is the only RTOS that allows to use OpenCV on Cortex-m MCUs https://www.embedded.com/benchmarking-opencv-on-stm32-mcus/

When do you know if your project needs to move on from bare-metal to using an RTOS? then from RTOS to using embedded Linux?
As for Linux, it allows easy and fast creating a device with reach features, but it requires more powerful and expensive hardware platforms, it has some questions with hard real-time, and it is less secure after all it is a general-purpose OS. We try to solve these cons of Linux in Embox. It combines prop RTOSes and Linux and allows run Linux software everywhere including MCUs
