The list of applications for a CAN bus is pretty impressive. Trucks and buses, passenger cars, off road vehicles, passenger and cargo trains, maritime electronics, aircraft and aerospace electronics, factory automation, lifts and escalators, industrial machine control, building automation. CAN is al...

Hello during the years I have developed some practical knowledge about CAN bus cabeling in industral systems focused on safety and there are some rules that should be folloed: 1 Cabeling I normaly use a cable with one data pair for the CAN bus and one pair to supply 24V bus power to the nodes. By us...

Hello
are there any news on the release of the dsPIC Version 5? Any date set for a release yet?

Hi,
after downloading the 5.4 update today I am not able to compile to HEX any longer.
I get the following message:

Compiler can not be started without a host program (code 120)

Any ideas how to fix this?

Hello
do you have any timescale when we can expect the Version 5 of dsPIC? I am realy looking forward to this new release.

Hello, in order to be able to change the Can address i had to use the following C code together with the 30F6012A chip. The macro SetTX Address does not work at all. // Request config mode. C1CTRL = REQOP_CONFIG; // Wait till desired mode is set. while( (C1CTRL & CAN_OP_MODE_BITS) != 0x80 ); C1TX0CO...

Hello
an usefull addition to the current CAN component would be a macro that changed the speed of the CAN bus as you can change the baudrate in the upgraded RS232 component in FC 5.

Hello good to hear that a Version 5 of dsPIC is on it''s way. Something I would like to see is that the dsPIC is brought up to the same standard as the 8 bit version in funcionality. It would be good if better support for the 30F601_A series could be supported. It seeams as there are still problems ...

It seams as if there is a problem to place both the SetTxID and SetTcData macros in the same loop. They both work induvidualy if there is a Send macro between them or if theu are in separate loops. It is a bit unpractical but at least there is some kind of workaround for the problem. Do you have any...

Hi. You are using CAN1? The can hi and can lo connected right (it isn't one or two times when I have mixed the can hi and lo :oops: ..)? I'll try test the can transmit at dspic when I have some time, but it might go at next week... Have you use that optoisolation before at 18F? Mika Hello yes, I am...

Ok, I found something interesting... The macros SetTxID and SetTxData seams to be writing the CAN controller registers in a faulty way. If i set the TxID and TxData in the CAN component settings and they are written when CAN is initilized at the start of the program,I get transmissions without error...

Hello yes I am using the MCP2551 as the driver. I also have an opto isolation between the 30F6012A and the MCP2551. When I measurethe CAN traffic I am using a can>usb analyzer on the output of the MCP2551 (with proper termination). The anlyser can be seen on http://www.canusb.com and has worked well...

Hello I've beeen working on a project that uses the internal CAN controller on a 30F6012A chip and there seams to be some problems. The problem is that it seam that it is not possible to populate the frames with any data. Regardless of what I put in to the TxData macro, All I get out is 00 as a valu...

Hello
any news about the updated c file that works both with the 4D displays and the RS232 component?
Can you estimate when it will be released for upload?

Thanks

Yes it would be good. I havea project that will use both the 4D display AND RS232component.

Yes.... it kind of works. I can compile and run projects that is using the 4D displays. But then I try to compile a projec that has the RS232 function in it, it fails and I get a lot of error messages abot unsigned charachters. Switching back to the old CAL file solves the problem. But then compilin...

Hello
I see that you have added some more of the 4D displays to the webshop.
Is the updated gLCD component available for download somewhere?

Oh.. I thought it wa released since you can buy the EB071 in the webshop.
Any idea how long it will take before the 4D displays are released?

Hello I have done a program to test the EB076 E.Block. It runs in simulation but when I try to compile I get the following errors: gLCDTest2.c Starting preprocessor: C:\PROGRA~2\Flowcode\v5\Tools\boostc\pp.exe gLCDTest2.c -i C:\PROGRA~2\Flowcode\v5\Tools\boostc\include -d _PIC18F4550 -la -c2 -o gLCD...

Hello is it possible to somehow use the 4D gLCD macros from Flowcode Version 5 in Flowcode ds24 Version 4? I was thinking of the E-board EB071 and the upcomming EB076 that would be very nice to use with the 30F range of PICs. Or do I have to wait for a version 5 release of Flowcode ds24? Is there an...

It seams to be working. I have tried a small test program that writes and reads the eeprom successfully. Thanks for your help.
These beta files, what release are they part of?

Hello,
if possible, a fix for the 30F6012A EEPROM problem would be best. I have already designed a pcb for this chip and I have also spent a lot of time on the code for this chip.
If it not possible to solve the problem, please test the 30F5011 and see if it works.

Thanks.

yes I know about the search tool. The problem is that 30f6011A, 30F6012A, 30F6013A, 30F6014A does not work with the EEPROM component and current compiler.
30F5011 could work. Have you tested it with the EEPROM component?

Hello Ben, any news or a solution to the EEPROM problem with 30F6012A yet? It would be realy good if there was a solution: Otherwise I have to change chip for this project. Do you know any compatible chip (not 30F6012 since it is not recommended for new designs) that the EEPROM component has been te...

Hello Ben
Any news on how to get this to work? I am stuck at the moment with this project and I realy need be able to successfully read and write to the eeprom to move forward.
