Hi

I need some advice to continue testing the "Tasterschnittstelle 8-fach LPC"
Bild

I finished building the kit I got from the freebus Online Shop.

So, I guess that the LPC uC is empty and it has to be flashed. (am I correct?).

I understand that a LPC programmer is necessary. (right?) no simpler way is possible (RS232, etc..)

Could someone answer those questions:
1- the firmware (hex) file has to be downloaded from freebus git repository ? where exactly ?
2- Is there a special version to use it as a 8 way button interface (with no led) ? (is it possible, or only 4 button + LED)
3- what is the simplest solution to get a LPC programmer ?
I see on ebay, as mentioned on the german forum:
http://cgi.ebay.fr/USB-ISP-Programmer-f ... 0955403528
did someone try this ?
It seems that the USB programmer mentioned on the freebus site is not available in the freebus shop.


Thank you !

No, this programmer is not working with the p89LPC9xx family.
look here: http://www.freebus.org/content/tasterschnittstelle-0 at 8-fach Tasterschnittstelle
you can also use the in8 soft (newer backend soft)working with DIN RAIL Module from my page
www.krieger-elektro.de/freebus click the red link to the overview(sorry because its german).

Hello !

I have bad experiences with the freebus programmer (Seems to be that you can use it only in ISP mode, not with integrated DIP support).

I have bought that one:
http://www.teamfdi.com/development-tool ... USB-DONGLE
I bought it at Mouser (about 20 €).

It has many nice features (eg. ISP, but also ICP when you have erased the bootloader...), and I am really happy with it.

The file for the µC is on the page of the tasterschnittstelle (but you have to be logged to see it)

Tchuss !

Hi,

I have ordered one from Mouser.

Thank you.

Hi,

Thanks again.

I received TeamFDI USB-Dongle:

Pierre-Marie: How did you connect the usbdongle to the BCU ?
There is the connector with 6 signals on the BCU :
VCC, VCC_IN, RST, TXD, RXD, GND

On USB Dongle, one can find J3 connector that can be connected to sample boards.
There is also connector J2 (6 pin).

Do you use J3 or J2 ?

Help appreciated.

Thanks
Laurent

Hello !

I use jumper J3.
Perhaps it will be easier to have your adress for private explaination (even better, if you are french -as the name seems to be-, on the phone...).

Regards

Pierre-Marie

Hi,

First of all, thanks to Pierre-Marie for the useful hints he provided.

Eventually, I managed to have the full process work:
- building
- programming (with teamFDI usb programmer, in ICP mode)
- programming with ETS4
- testing with actuator on BUS

The problems I got were:
- I could not find the hex file on the site, because I selected "English" as language, and the page where the hex file is located is only visible when in German mode.
- I programmed one BCU with a wrong hex file: in8Taster.hex, and I could not recover the BCU, it seems it did not like it, even ICP mode does not work.
- I purchased a daughter board: DB-TSSOP-LPC922, to go with teamFDI's USB-DONGLE programmer, it's helpful to test flashmagic software, but using it to access J3 signals (on USB-DONGLE) works, but I did not like to have 2 LPC in parallel
- So I built a custom connector, this was the trickiest part, to access the J3 connector with all signals, including ISP and ICP.

Now that I have validated my ability to use the device, I have to count how many of them I need.

Thanks for the help I got from P-M and also on IRC #freebus !!!
