What is initialized data variables, and what is non-initialized data variables? (Because my words describe not necessarily accurate, they tend to give some examples to assist in understanding the text.)ĭefinition of a variable: int nTimerCount = 20 nTimerCount variable is initialized variable, i.e. How to set up a non-initialized data variables are not initialized to zero, which is to be discussed in this article.īefore giving way to look at the code and data storage rules, why default after the property, and a reset RAM uninitialized variables are initialized to zero where of it. And Keil MDK default, any form of non-Reset will initialize the variable region of RAM data is cleared. Some industrial products, when the system is reset (non reset), the reset may be required before the holding live data in RAM, on-site for rapid recovery, or do not, restart instantaneously reset the field device. In general, we generally use flash to save some of the last saved data, so that the next change flash variables read at boot configuration or you can read back the last last last data values, but keil fact, there is another way to save data, Look below decomposition.
