Yes, but it never became a module
Management of SIM900 is in main program and functions are intended to what I needed (only send SMS).
If you want I can give you some tips..

Re: Program origin and banks
Hello Jerry,
I had based on this post http://www.microchip.com/forums/m252258.aspx but rightly once you've set CPn and make sure the bootloader with CPB the FW can not be changed and read than a full erase right?
So EBTRn are superfluous and are those that prevent me from the TBLRD*.

Re: Program origin and banks
Hello, with 18F2682 and below config I disable the code read from MPU.. CP0 = On CP1 = On CP2 = On CP3 = On CP4 = On CP5 = On EBTR0 = On EBTR1 = On EBTR2 = On EBTR3 = On EBTR4 = On EBTR5 = On CPD = On CPB = On .. but this also prevents the use of the TBLRD* and always returns 0. So the idea was put ...

Program origin and banks
Hello,
I need to protect the source, but read a part of the ROM containing some string constants.
I am aware of the configuration parameters to protect the individual banks and would like to know if and how I can position the origin of the program from a specific bank.
Thank you.

USART2 with ISRRX
I want to use the ISRRX on second USART on a 46K22 and I rebuilt a ISSRX for the second USART renaming it UartBuffer2.bas I still have not the MPU so I rely only on compilation and I noticed that in the USART2.BAS module there is a specific reference to 18F26K22 (which is exactly the same family of ...

Re: MQTT Message Queue support for W5500 eth module
Yes Jerry,
Itead is one of the few that uses the SPI pins on the connector D9 / D13 instead of the 6 pin Arduino ICSP central header, that in some cases could also touch the ICSP Firewing header if it is mounted.

It's a shame that there is only SMD!
Is there something similar with old features DIP?

Re: MQTT Message Queue support for W5500 eth module
Hello Jerry,
excuse is slightly off topic (but Firewing is of the same family )
David suggested to me an itead shield http://imall.iteadstudio.com/im140725005.html which at first glance should work with Firewing ..
Someone has tried it?
Thanks.
PS: Then move any replies in FW forum

MQTT Message Queue support for W5500 eth module
Hello,
on wiki you can found an implementation of MQTT, a small machine-to-machine/"Internet of Things" connectivity protocol, as expansion of W5500 eth module.
