FSBUS Cant Write CID

Well thats the thing.... Im now able to get allllllllllll of the Boards working now DO64, IO, 6Pack all of them

Hello,

I have a strange behavior on my 6 pack Fsbus display card. After CID set, it randomly reset to 31, after 1 or more DC disconnects. How to fix it? All the jumpers are always sets, cause without jumpers displays doesn't power on. Is this normal?

Thanks

Francesco

Hello,

please describe what you do step by step.
Also make a picture of the board with the Jumpers for setup the CID and normal usage.

Hello,

first I set the first jumper to flash the first CID. After it's set I test with it with Fsadmin and it works fine with correct CID. After that, I remove the jumper from the first place and set it to the second place to set a new CID for the second display, and so on...After that i set all jumpers (as you can see from the picture, the four jumpers are soldered), and it works fine, but after 1 or more DC power disconnect the CID reset to 31.

Ok, the way ist ok.
How much voltage and current have your power supply?

Hello, voltage is 5 V, current I don't know, but i have an IO board and it works very well. It's very very strange!

I know that Problem, in the most times it is a to low power supply.
In the moment when you start all the Power supply dosn´t supply 5 Volts because to may "users".
When the Voltage is lower than 3.6-3.9 Volts it is possible that the EEPROM Part of the Atmel delet all.
Get the Atmel Datasheet and setup the "BOD" or use a more stable power supply.
I use 5V 20A.

ok,

i'll try a more powerfull power supply. Currently i'm using 5v from usb port!
