42 - name: PrintFormat [SETTING]
45 # Description is in Markdown mark-up
48 This block allows to log a double value to the SD-RAM. User needs to provide a valid PrintFormat
49 string to format and register the double value on the log. The PrintFormat string should include
51 1. For the block ID. Any valid integer specifier.
52 2. For the value to log. Any valid double specifier.
54 Note that the value of PrintFormat is inserted raw between quotes on code generation and thus there
55 is no validation on it. Error to provide a valid PrintFormat could generate compilation errors or
56 even run-time errors (normally this generates a warning on compile time). Note that the function
57 for logging used is `rpp_sdr_printf()`, which is a blocking call, and can potentially overrun the
58 step. The ErrFlag will set if `rpp_sdr_printf()` returns an error (for example out of memory),
59 but will clear back if the next step the call to this function is successful.
64 - Compilation and general use.
66 - Faulty situation for the ErrFlag to set.
