serial blocks are hidden in adfruit and maker #4040
Comments
Webusb is still in experimental phase and questions are mostly related to security and usability of the prompts. Also webusb is not a web standard and still a proposal for W3C. |
Does this mean the missing serial blocks are still being moved to the
console tab. What about write number, write line, read line, read line
until, read string, serial redirect, etc. I would hate to see all of those
blocks go away. It will really impact the functionality of working with
serial data using blocks.

Serial blocks are renamed to console as they are more student friendly and
should work on windows app.

write number: We are going to fix console.log to accept numbers as well. So one doesn't need a new block. Today you can use the join block in text category to do that. We don't have plan for the following. Why do you need them? Can you let us know the user scenario? |
That is really good that numbers will also be accepted. The reason for read
line, read line until, read string, serial redirect, is to interact with
other application such as grasshopper3d
https://www.youtube.com/watch?v=_E1NO4mJUgg or processing
https://www.youtube.com/watch?v=7iMMUO0J3h4 or other apps that communicate
via serial. You can send values via serial to control geometry in those
apps and then use serial read to change a color of an led or play a song
for example on the circuit playground express based on the incoming
message. You need redirect since you can only access one com port at a
time. Also another really important reason is in the maker app if you want
to have pass through serial using wifi module such as esp8266 or bluetooth
added onto the board in order to interact with a tablet via serial you
currently can't do it. I've noticed all sorts of IOT add ons for the
microbit such as https://github.com/DFRobot/pxt-Obloq,
http://muselab.cc/product/muselab-wifi-iot-shield-for-microbit/,
http://www.instructables.com/id/Use-HC-06-Bluetooth-Module-to-Realize-Microbit-Com/
, https://www.elecfreaks.com/12224.html. To not be able to use similar
hardware on the maker app would be so unfortunate. All that is needed for
any of those particular hardwares to work is an rx,tx,3v,gnd and a serial
port defined. The maker app already has many sophisticated features not
available on the microbit such as expanded math functions so it can do some
advanced stuff and it doesn't seem like it should be so oversimplified that
you limit functionality by privileging over simplicity. You just have to
have serial it's at the heart of how all microprocessors work I am begging
you guys to make sure to include those blocks. On this page
https://makecode.adafruit.com/reference/serial it also clearly states that
The Adafruit Circuit Playground Express can read data from and write data
to another computer or device with a serial connection using USB. I think
it's important to have it able to do just that. When I first saw the maker
app I was so excited because I thought this is going to be even better than
the microbit app as a learning platform and it will enable all sorts of
things to be made with an even greater depth of exploration. Because of the
breadboard interface it encourages exploring and interacting with all sorts
of hardware but most of the hardware is often controlled with serial
messages. I think you guys are doing great work but please enable serial.

Thanks for the feedback @machinehistories Are you asking for serial through pins or serial through USB? |
Pins would be ideal for interfacing with hardware and other apps but serial
over usb could at least work with interfacing with other apps and or
terminal programs. thanks

Thanks! Note I will mark this as feature request. Reason is the serial over USB is not implemented in CODAL runtime and will need work to be enabled. It is not just enabling these blocks. |
Feature requests in this bug: |
Amazing and thanks I look forward to using it and keep up the great work

In the adafruit circuit playground and in the maker tool the serial blocks are hidden. You can access the functions in java and you can see the serial blocks listed properly in the support documents for these two apps. I've tried the windows 10 adafruit app and it has the same missing serial blocks issue running the app locally as it does running it on in a browser on the web. Also may I ask how to use the webusb. I saw mention of it and it sounds exciting. It will be way easier for students to upload using a direct usb connection. Keep up all the exciting work. The serial blocks are still available in microbit.
