Hello David,

I enjoy learning when ever I can. I clicked the Links and noticed the Matrix Videos are for Flowcode 4.

The YouTube Matrix's was excellent with one major draw back there is no audible human voice to help enplane the actions. Just nice sleepy music ? Unless I missed something.

John

Hi John,

Yes unfortuantely the Flowcode v4 videoes are only music (or mostly silence in the later ones!) we do wish to improve and update them at some point, by adding annotations and making them HD, (im not sure we will venture down the voice route just yet).

Hi,
I tried to test tutorial 23 using flowcode V5, I found a message. I am attching a pdf for you to see. Please let me know how can I get rid of this problem.

Hi kalim007,
What hardware are you using ICD on?

Currently for PIC, as far as im aware, it can only be used with EB006 V7 and above programmer.

Or with Flowkit:

If you are using either one of these, if you can post the flowchart altered for your settings then I can have a look for you.

I am using EB006, but do not know if it is V7. I am uploading flowchart here.

Hi,
There is nothing wrong with your Flowchart as it allowed ICD to communicate with My 16F88 mounted of EB006 V7 with no issues.

So it sounds like a hardware issue.

Make sure the following are in correct positions:

ICD2/USB jumper is in USB position (that caught me out at first)

RC/XTAL switch is in XTAL position.

OSC/A6&7 jumper is in OSC

PSU/USB jumper is in PSU

If you struggling to establish communication, then temporarily disable ICD, and create a 1Hz flasher. Make sure osc LED time on and time off is correct. If it is then try again with ICD enabled.

When I run ICD I start with single stepping by pressing the F8 key.

Sometimes Disconnecting both power and and usb leads , then reconnecting may help.

If you microcontroller programs ok, then if hardware and flowchart are set up correctly, there is no reason for ICD not to work Martin

Martin,
Thanks for you brief answer. I checked all jumper except OSC/A6&7, because I do not have that jumper in my programmer board. I also found my board is EB006 -00-06, that means v6 not v7. This could be the reason for not working. If I disable ICD, eveything works fine. I can compile, download the program in board.

Hello,

Yes I can confirm that the ICD functionality was added for the v7 EB006.

Hello,
I have another questions regarding training video 26 (i.e. advanced component 3). In simulation everything works. It was assumed here that a char was transmitted and received in same microcontroller. (At this moment I am using PIC16F877A) But i want to transmit char from one microcontroller and want to receive in another microcontroller. So, there are two microcontrollers in the system.I want to verify with you following information.

1. Pin 25 for transmission
2. Pin 26 receiver
3. Baud rate has to be same

Do I need to connect any pins? Is there anything else I need to know before trying to build this?

Thanks in advance for your help.

This questions probably was too complicated to answer. I actually found answer of my question. I simply have to read the datasheet of the micrcontroller first that I am going to use for serial communications. As a simple test, I am going to read a character from a keypad and I can transmit that character. On the other side (i.e. receiver end) I can read that data and output it to LCD. This way, I can verify the serial data transmission.
I have to write two programs for two microcontroller.

I am working on it and hopefully will be able to post update in a week or so.
