34 - { name: "Analog Input Pin Number", type: "uint16" }

40 # Description is in Markdown mark-up
43 This block allows to read the analog inputs on the RPP board. The
44 ErrFlag should if raise `rpp_adc_update()` or `rpp_adc_get()`
45 returns error. `rpp_adc_update()` is called just by the first DIN
46 block in the model and thus only the first block could raise the
47 flag because of this. In case an error occurs the return value will
48 always be 0. Because the ErrFlag should never set, once set the
49 following steps will never clear it back.
54 - Compilation and general use.
56 - Faulty situation for the ErrFlag to set.
