Matrix user forums

Hello all.
I have 2 Questions
1) I can connect via USB connector with matrix eb-006 multiprogrammer board,
but with the QL200 I am getting a "USB not connected" error.

Does Flowcode 4 support RS 232 (DB-9) connections?
Thanks,
Lisa L

Hi Lisa

1) If i read your post correctly, you are trying to program a QL200 Dev board with flowcode.
I don't think this will work, as flowcode will look for its own firmware on the programmer i.e the EB006. The EB006 driver is not compatible with the QL200.

Also , interestingly your board looks like a clone of the MikroElektronika board.

To use this board with flowcode you will have to use the option to compile to hex (Chip - Compile to hex) rather than to the board.
Then use the dev boards programming software to load the hex file to it.
Before compiling you will have to make sure the connections on your board match the flowcode components.

i.e. for the LCD RS = Bit4 Enable = Bit5.

2) Flowcode will support the RS232 protocol using the EB015 E-Block plugged into the EB006.

This is in the flowcode comms library.
This is only available in the Pro version. if you are running the home/student version I believe Matrix will let you upgrade for the difference in price between the two

Hope this helps

John, with his second question he wanted to know if it is possible to use a COM port to program a microcontroller.
This can't be done with flowcode.
Flowcode has it's own multiprogrammer board.

Thank you! Very informational.
It's good to know I can still use the QL200.
As far as the addressing goes,

"Before compiling you will have to make sure the connections on your board match the flowcode components.

i.e. for the LCD RS = Bit4 Enable = Bit5."


Does Flowcode not start addressing at 1 instead of zero or something?

Thanks again,
Lisa

Hi
Sorry I might be confusing you

Before compiling you will have to make sure the connections on your board match the flowcode components.

i.e. for the LCD RS = Bit4 Enable = Bit5."


Flowcode lets you change the way the components are wired in case the default settings of 2 components clash.
The Matrix E-blocks hardware can be patched to suite
Proberbly wont effect you, but if you find things dont work as they should let us know and Im sure someone will help

John,
Thanks, I understand what you are saying.
I have written a test program and loaded it in via the QL200.
All is a go! thanks again!

Thats good news
Thanks for letting us know
