Hi, I am far more likely to be able to program a chip by using a Pic straight out of the box ( never been programmed before), restarting Flowcode immediately before I hit 'program to chip' and not attempting to autodetect the chip. Once a chip has come been programmed or if I have used autodetect pr...

I have persevered and I have found that I can get the ZIF programmer to very occasionally program a chip. But in no way is it reliable. My PICKIT3 will program the same chips every time with no problems at all. I have always found Matrix equipment and support to be second to none but I think there a...

Hi David, Yes it is detected as a Matrix Programmer. The screws are black. I have just removed and reinstalled Flowcode/PPP, same result. I have removed all previous versions of PPP from my machine so now I am definitely just running 3.11. And the error message is different. Now I get the warnings a...

Hi Ben,

It is unable to detect any chip. I have tried several different types of 16F and 18Fs in both sockets, with the external chip select jumpers moved appropriately. I am happy to open it up if that is the next step.

Hi, I was really happy with how quickly this issue was acknowledged and satisfied with the resolution. My replacement unit arrived promptly also. I have only just today got around to opening the box and plugging it in however. Unfortunately this unit is behaving in exactly the same way as the previo...

Hello, I have just taken delivery of my ZIFPic micro programmer and I am not having much luck with it. I have installed the drivers by pointing to the supplied CD (ESLAM V2.4). My PC now recognises the device as a Matrix PICmicro Programmer. The driver version is 1.0.0.6. The problem is that the pro...

Hello, There seems to be an issue with the the CAN2 component as I get the following errors when compiling: test.c(237): Illegal redefinition of symbol: TXB0EID8_VAL test.c(238): Illegal redefinition of symbol: TXB0EID0_VAL test.c(239): Illegal redefinition of symbol: TXB1EID8_VAL test.c(240): Illeg...

Hi, Unfortunately that was a few PC's ago and I don't appear to have archived any of those file. I have done a really quick & dirty example of how to output a DTMF 7 using the Holtek 9200B in parallel mode. Hopefully this will give you enough to go on with. This example, using a 16F877A, assumes...

Hi,

If you can I would suggest using a separate DTMF chip. I have used a couple of different ones but the Holtek HT9200B used in parallel mode is a particularly simple device to incorporate into a Pic/Flowcode Project.

Good Luck
MW

Hi,

Did you have any luck with this?

Hi, I have had a play with this today, but have not had much joy. I downloaded the new CAN2 component and installed it as per instructions. I then went into custom code where I found the line in question but found it already to be edited as per your post. I then wrote a very simple flow chart where ...

This is still something I could really use

Hello, I have been using the Can2 Component with an 18F2580 and an external Can controller with great success. As I would now like to include a USB port I am considering changing to a micro with USB functionality such as the 18F2550. Looking at the data sheet for this device however I notice that un...

Ben this worked a treat. I am now up and running.

Thanks very much
MW

Hi,

I am running 4.3.7.63. No joy.

Thanks

Apologies. I should of posted this in the Flowcode V4 forum. Also I should explain I am trying to use the 18F2580 with an MCP2510 not with the internal can module.

Thanks
MW

Hello, I have a different problem along these lines. I have written a small program for the 18F2580 using the Can2 component. Whenever I try to compile it however I get the following errors: Illegal redefinition of symbol: RXM0EID8_VAL Illegal redefinition of symbol: RXM0EID0_VAL Illegal redefinitio...

I would start reinstalling the USB drivers. My guess is that plugging in the programmer is causing a conflict somehow and VB is opening as your default debug editor.

No problem at all. Thanks very much

Hi,

Has any further thought been given to if or when extended identifiers will be included in the component?

Cheers
MW

Hi Ben,

I primarily require extended identifiers, so if it is possible to update the component to include these it would be a massive help.

Regards
MW

I have a similar problem. I have an 18F2580 on a custom board which I am programming by breaking out from a V3 development board. I programmed it the first time with no problems. The next time I tried to program it I got a "chip failed to erase. Do you wish to continue? error" I hit yes an...

You are right on all counts and as a result I have things working well now @ 8MHz.

Thanks very much and apologies for the late response, I have been off line for a bit.

MW

Steve,

This is a great development and something I have an immediate use for.

Is there a way to use to use the internal CAN modules to transmit 29 bit message ID's?

Thanks
MW

Hi, I have developed an application in Flowcode, set to the default compiler options, utilising a 16F876 and an external 20MHz oscillator. This application relies on reasonably accurate timing and it is working well. By reasonably accurate I mean that the delay icons have been sufficient. I am now a...
