Today I’ve modified USART library. My library uses receive interrupt. After that, it just save data into cyclic buffer. User actually don’t know when that happen. Today, I was working on some project, where I need to know exact time, when data arrived on USART. For that purpose, I’ve modified USART library. To be able to know exact time when data arrived, you have to add defines in your defines.h file:
//Enable custom receive interrupt handler for each USART
//Enable for USART1 and so on
//Put only this defines, you want to use
Then, you have to manually create a function...
