The UART driver should fulfill the basic functions of such a driver, these are: putting data interrupt based into an output buffer of the microcontroller and reading data back from an input buffer without losing any data.
Below you can see a snippet of an example uart-driver for an STM32 Nucleo board, to find example implementations for other boards, check out our examples repository.
In order to be able to run se-scope, you have to create an instance of the ScopeFramedStack. The parameters of the constructor are structs, which define constants like the number of channels. For more information, see the code snippet below.
The ScopeFramedStack_run method should be called in the main loop of your program.
If you are using a RTOS, the ScopeFramedStack_runThreadScope method should be called in one of the threads. Se-scope-target is designed to be used with a RTOS and provides a lot of features for thread-safety like built-in mutexes. Take a look at our examples repository to see implementations of se-scope-target running in a RTOS.
se-scope-target defines a transceiver from which you can get the processed data to send and to which you can forward the data that is received from the gui application. To use the transceiver you have to instantiate it in your UART driver (Step 2) by getting it from the scope stack as it is shown in the example code below.
Once the transceiver is correctly set up, you can simply use its get-method to copy data from the scope-stack into the output buffer of your UART driver resp. the put-method to copy data from the input-buffer into the scope-stack.
After you have configured the scope-stack (step 3), you can announce variables to the stack. To do this you get an AnnounceStorage object from the scope-stack to which you add the variables as well as their name and data-type.
Note that you can announce as many variables as you want, but you only have a limited amount of channels to stream the variables, so se-scope-gui can only display as many variables as the amount of channels at the same time.
In order to run the se-scope-target (step 3) you have already created a logger instance, defined the message-priorities and passed both to the scope stack. With the write-method of this logger instance, you can easily transmit log-messages to se-scope-gui (see example).
