MicroBlocks VM To SNAP
via WEB USB Serial
This project was made possible by JavaScript assistance from dardoro from the SNAP User Community.
Using his Simple Serial Library, it is possible to communicate from SNAP to any and all USB connected Serial devices.
MicroBlocks supports a variety of micro devices in realtime. Visit microblocks at http://microblocks.fun/
micro:bit and a PC running SNAP are connected over a USB cable operating at 115200 baud.
micro:bit is running a MicroBlocks program called "VM2SNAP.UBP"
SNAP is running a program called "VM2SNAP.XML".
To RUN:
- Connect a micro:bit to the PC via a USB cable
- Load MicroBlocks program onto micro:bit and synch
- Disconnect the MicroBlocks USB connection.
- With the micro:bit still connected to the PC, load and run the SNAP program.
- Select the USB port where micro:bit is connected.

1699416_input00Reports the portion of the first input (string) starting at the position given by the second input (counting from 1, like LETTER n OF) and ending at the position given by the third input (also counting from 1). If the third input is empty, reports the portion from the first position to the end of the string.
If a position number is negative, counts from the end backward, so -1 is the last character, -2 is the next to last, etc.pt:o texto de _ entre as posições _ e _ , inclusive

Reports the part of the first string up to the first instance of the second string inside it. If the second string isn't found, reports the entire first string.pt:o texto de _ antes de _
If input is TRUE, comparisons made by functions in the string library will be case-independent (so "FOO" = "foo"). This is the default.
If input is FALSE, comparisons will be exact.pt:altera comparações ignorando distinção minúsculas/maiúsculas para _

copy of datasplitmerge11#1#2The second input is an "association list," a list of two-item lists. Each of those smaller lists has a "key" as its first item and a "value" as its second. ASSOC reports the first key-value pair in the association list whose key matches the first input.ca:associació _ _
11This block carries out the given script for each item of the given list, like the primitive FOR EACH.
What's different is that it provides the # variable, which will contain the item number in the list of each item in turn, 1 while processing item 1, and so on.ca:_ per cada _ de _ _
1Takes a (possibly deep) list as input,
and reports a human-readable text form
of the list (namely, Lisp notation).
Will not work on circular lists.()SENTENCE is the main constructor for sentences, represented
as lists of words. It takes zero or more inputs, each of which can
be either a list or a text string. If a list, the input is assumed to be
a list of words. If a text string, it is converted to a list of words using
SENTENCE→LIST. Then all the lists of words are appended to form a new list of words.
If the inputs are lists of lists rather than lists of words, SENTENCE,
like APPEND, does only one level of flattening, reporting a list of
all the items of all the input lists.ZIP takes any number of lists as inputs. The lists should all be the same length. ZIP reports a list of lists in which the first item is a list of all the first items, the second item is a list of all the second items, etc.
Viewing the inputs as the rows of a matrix, ZIP reports its transpose.1The identity function reports its input.Takes as input a function of N inputs and N lists.
The function is called with item 1 of all the lists as its inputs, with item 2 of all the lists as its inputs, and so on. (The lists should all be the same length.)Takes a sentence in text string form and reports the sentence as a list of its words.de:Satz $arrowRight Liste _

}This block creates new variables on the selected scope: global (for all sprites), sprite (for this sprite only) or script (only for that blocks stack) with the names given (in 'names' list).

Each name will make only one variable deletion, and this will be the variable found following the scope order: 'script' -> 'sprite' -> 'global'.
If we have a "testing" sprite variable and also a "testing" global one, deleting "testing" will delete only the sprite one (Yes! we can also do "delete var (testing, testing)" to delete both.
If one variable does not exists (in any scope) an error happens, stopping block action in that point. You can check it before with the "does var (name) exists?"block. pt:remove as variáveis _
