Confirmed.

Who needs the MZ series chips - the uM chip has 4294967295K(3.9TB!

) of RAM - cool!

Plasma,
Most IR receiver modules salvaged from an old DVD, VCR, TV, etc. should work for the uMite. You want the 3-pin module that filters out the 38Khz IR clock and gives the data out. If you have to buy one the Vishay TSOP4838 from Arrow Electronics works fine, just make sure you get one for the 38Khz clock frequency. Hook it up as Geoff shows on page 15 in the beta 6 manual.

Geoff,
Thanks again for the IR support, looking forward to the IR send in beta 7. I spent many hours back in December coding the IR function in assembler on the 8-pin PIC12F683. Just 8 or 9 lines of code put the IR remote codes on the LCD display on the uMite 44. Your MMBasic is so cool !!

i am really interested for the ir receiver as Geoff shows in the beta 6 manual ,but unfortunately i cant get this in germany. can i use other receivers ?

Thanks very much Plasma (and Grogster for confirming it), that is what I would call an "entertaining" bug. I will fix it in the next beta.

Yes, you can use almost any receiver. They all seem to work the same and even have the same pinouts. The devices that I quoted in the manual were just examples.

Any reason COM1:EN can't be moved from pin 24 on 44 pin chip closer to actual COM1 pins 8 and 9, possibly pin 10. Would make PCB layout more logical and easier?

Hi All..
Just recieved some 44 Pin's pic for MicroMite and searching on ebay
found these adapter Pcb's that could be of interest
for others Building a MicroMite

i hope this is allowed here..

Hi atmega8..
That is true but pollin wants 6 euro for shipping and dont take PayPal from
Denmark
That Means i have to use europayment thats 6 euro more..
The ebay link ships me 10 pcb's including shipping for 8.45Us dollars..
but i think i am getting a bit offtopic so i stop here..

Hi All..,

Micromite feature idea to consider.

As i micromite is growing in features and has communication options: IR, serial,
may be would be nice to consider some wireless option.
as cheap radio module Hope-RF RFM12B. It uses SPI interface and is quite popular as good and not expensive RX/TX radio module.

I was thinking of providing support for the NRF24L01+ for RF communications.

Comments anyone?

Can't that be done through a library or BASIC example? Like the DS18B20 could?

I would also tend more to the RFM12B Modules.
Very cheap, popular, receive and transmitt,.....

WOW, support for the NRF24L01+ would be awesome! (And that from a 49 year old)

I used them on arduinos and they are (through using a library) super easy to use
Now the hard thing is of course the library and the one i use works good.
Thi is the library: http://maniacbug.github.io/RF24Network/index.html

It is in C(++), it creates a network of nodes using a tree structure.
Each rf modules can handle six 'pipes' at the same time making it possible for each node to connect to 5 others. The library takes care of delivering the messages by routing it through the right nodes. Works good.

Underlying is a simpler library that just talks between two rf modules. In many cases that can be enough

Another library i found that uses a PIC but did not use yet (never got a order through) is this: http://www.openbeacon.org/OpenBeacon_Active_RFID_Project

That is another great use of it, by using it as an active RFID it can be used for identification and security.

I am getting excited, because if one of those type of uses is available from MMBasic, just wow!

If you need a few for testing i have a whole bunch of them :) We use them in the makerspace with the arduinos.

I got about 100 meters range with those in open field. At home it works through at least 1 concrete wall/floor and 15 meters distance (Could not get more far than that inside, so practically the whole house, also upstairs.)

Can someone post a link to these RF modules, so I can read about them?
Inclined to agree with atmega8 - transceiver would be the best idea, then it can act as a transmitter or a receiver - my 2c only.

RFM12B? No way!!! I have a bad experience with those modules! Very tricky to make them work and the amount of required software is huge! You'll see Geoff, is not worth the effort. But yes, support for NRF24L01+ would be fantastic!

Support for wireless NRF24L would be another huge milestone for MMBasic related controllers. I would vote wireless as the next MOST important addition.
