Re: Compiling the example microcontroller firmware

Hello, attached you can find the sample code with the makefile. For using the makefile, please have a look inside the user manual ( PCAN-Router manual in PDF format (English)) from our PCAN-Router. Inside this manual there is a description how to build your code with a makefile (page 25). regards, F...

Re: Compiling the example microcontroller firmware

Hello,

I will try to create a makefile, but this will take a bit time. Because I have to test this solution. So that it is possible to create a binary file without µVision.

regards,

Fabian

Re: Compiling the example microcontroller firmware

Hi,

we have changed this a for a while. It is only possible to compile with old µVision Version (V4.13 or less). Is it possible for you to use/get this Version?

regards,

Re: Compiling the example microcontroller firmware

Hello expor,

could it be possible, that you have updated your µVision? The problem is, that Keil has updated the way calling gcc and the ARM-glue- file will not work with newer Versions of µVision.

Best Regards

Hardware issues found in revisions 3.1 and 3.2

We've located two issues regarding the GPRS-Link hardware in revisions 3.1 and 3.2: CAN transmissions not possible after wake up by ignition (Clamp 15) Device won't start since some SD cards draw to much current We strongly recommend to fix that for you, or (with experienced hands) you may DIY. In t...

Re: Compiling the example microcontroller firmware

HI Rich, do you get the mail I have send to you yesterday and today? As I had written in the mail, let us phone to clear the problem with µVision. The size of the binary file is bigger because of the gcc compiler and the disabled optimization. We started to test gcc with optimization but when we cre...

Re: GPS-Tunnel function

Hi, I have just moved your new question to a new topic. Please don't mix up the debug system and the possibility to get all characters from GPS or GPRS. With the debug system it is possible to change the GPRS-Connection data and show your actual GPS-Position. Just press ?<cr><lf> to see what is poss...

Re: Message filtering (hardware filter)

Good morning, yes it is right that the system is hold when you enable the tunnel. But be careful with removing the while(1) loops. If you do so, the gps-Task or the gprs-Task have to share all incoming characters with this tunnel. So non of them will work correctly. What now happens is, that the gps...

Re: PCAN-USB & PCAN-GPRS Link

Hi,

it works when you terminate your cable. Just plug in a 120 Ohm resistor at both ends between CAN_H and CAN_L.

Best regards

Re: PCAN-USB & PCAN-GPRS Link

Hello expor,

all products from us are not terminated. So you have to terminate your cable or use a PCAN-Term (product page) on both ends. Without termination it is not possible to communicate over CAN.

Best regards
