Simple ProMicro UART Interface / FlashForth / LoRa

This video is an introduction to the ProMicro microcontroller board and the ATMega32u4 microcontroller running FlashForth. Very simple code is described to send data out the UART Tx port.

Excellent demonstration! As usual. Thanks.

[FlashForth]

Thanks for making these illustrative Forth videos. Something I never got around to, even if I thought about it now and then. I am usually using FlashForth on a chip with native USB support whenever it is allowed by the other peripherals I need. The PIC18F25k50 is particularly nice since it has an internal precision clock and only needs two capacitors and a USB connector to get going on a 5 volt system.
Many times I put the communication/logic to other interfaces in one or more background tasks. That frees up the operator task to observe variables and do some debugging.

Great introduction into the possibilities of atmega32u4 chip. Having an usb-port and therefore freeing the uart is a big advantage over the 328p. Was looking for something like this for programming flashforth. Thanks 0033mer !

Another swell video, so simple and clear.

Just to to make it explicit, the Forth terminal session is being supported by the AVR ATMega32u4 chip's USB capabilities, and the LoRa chip is communicating with the other hardware UART? I didn't know the Rigol Scopes would decode serial communications ... which Rigol scope is it?

Very interesting ! Btw, how would you communicate the data comming from this Lora tx module towards a Lorawan gateway, in order to process the transmitted data with the assistance of a broker ? I was thinking of TTN.

What flow control and error correction is required to stream longer messages of ~100kB over such a LORA module? Did you measure the real world throughput with the air time limitations LORA modules are supposed to enforce?

[AdityaMehendale]

The "hello World" does not _sound_ much longer than "hi" - Is this because most of the LoRa output is actually preambles, handshakes, and protocol-stuff?

[lshLee]

hello !

Thank you for watching your video. I'm getting a lot of help in learning Forth.
I have a question, Does Flashforth have a word like function of IA's "EXTEND" word?
If so what is it?

not a single video of yours got recommended in the last 4 months. I literally had to come look at your profile just now to notice you have in fact not disappeared off the face of the earth. Nice one YouTube :\ Moan ends
