Hi.I thought this question is more suited to education.I have been working on a STM32F091 C++ project just to get an idea code size, and I noticed that the size of the binary is huge even when optimisation is set to (-Os). I think its because the co...

Hi.I’m working on a Nucleo-411, using CubeIDE, and HAL, and I want to read 4 PWM signals from am RC receiver. That is 4 50Hz signals, with a pulse width ranging from 0.5mS to 2.5mS. I’m following the reference manual, and some examples, and so far I...

Just to complete this thread, one of the files contained an #include <iostream> statement. When I removed this, the code size came down to 88K, which seems about right for this project size.cheers

ok, I checked my settings, and that's the way they are set up already. This code I'm using compiles for a mega2560 AVR at just under 128K, but as it is, ported to STM32F091, it generates 241k of code. That a big difference.

Thanks for your answer TDK.Where do I place (-WL,--gc-sections) and (--specs) in the cubeIDE settings.

JW, great advice. Also I need to do some work at designing the staggered arrival of inputs.
