(void)(tmpreg); is causing warnings

[Bob-the-Kuhn]

Not a bug, just annoying.

Please add it to your "nice to do on the next update" list.

This is a follow up to PR 1015.

The line (void)(tmpreg); causes the compiler to issue the following warning: warning: conversion to void will not access object of type 'volatile uint32_t {aka volatile long unsigned int}

This warning, along with a lot of supporting text, is repeated often enough that it is the majority of the compiler output That makes it hard to find the real issues.

I think you can get rid of tmpreg by doing the following: REPLACE tmpreg = READ_REG(TIMx->BDTR); WITH ((uint32_t volatile)READ_REG(TIMx->BDTR)); // volatile guarantees this read is not optimized out
