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.

I would probably use boost::asio for that and maybe look into something this although that was just a library I found by doing a quick search online.
