Please export a senc file from the device and I will check the setup.

Thanks Thomas! for your quick response!

It looks like you have not updated the chemistry data in the data flash. Do you know which ChemID should be selected for your cell? If not, you can use our online GPCCHEM tool to try to find a good match. This should help with the FCC and RM values, although they will still be off until you have run the optimization cycle. Sometimes the shift register do not get cleared out and the LED light. You can try power cycling the EVM to see if this helps. You do not currently have the device configured to display the SOC on the LEDs.

Tom

Great Tom!

its works now on the PC, but I still do not have any indication on the four LED's on the EVM!

I have placed the four jumpers on A,B, C, and D and also the jumper on J1 are placed!

I have set the LED_Comm Configuration flag to F3 (Data flash), as I will have the four LED active all the time.

Any suggestions what can be the problem?

Thanks for your fast response!

Br, Niels

Niels

If you are using the shift register and four LEDs, then you will need to ony place the jumper on the EXT jumper position and the LED Configuration register to 33. If you are trying to use the four LED mode where the LEDs are driven directly from the device, then you will not be able to use the I2C communications port. You will have to use HDQ.

Tom

Tom

Thanks a lot for your great and fast support!

I can come further with the design now.

Have a great day!

Niels

Tom

1. When I use the shift register and set the LED Configuration register to 33 I get five aktive LED (LED5-9) should it not be four with 25% charge level om each LED? 
2. I find it hard to find a clear explanation of what each of the 10LED's (LED0-9) stands for and what combination I can use, can you help help me out on that?
3. If I change from I2C to HDQ8 I can not go back to I2C again! Do that means that I have to by a new EVM if I will use the I2C again?

Thanks for your time!

/Niels

I think that the gauge sends commands to light the LED selection + 1, but only four LEDs are populated on your board. The percentages associated with the four LEDs should be correct.

The SOC will be divided by the number of LEDs. e.g. every 10% for 10 LEDs, every 25% for 4 LEDs.

You have the temporary option to switch to HDQ mode on the bq34z100-G1, but it is permanent on the older bq34z100. (The one that you are using.) you can update your device to the bq34z100-G1 and the firmware is available on the product website. See page 42 of the bq34z100-G1 TRM for information on switching to HDQ mode.

Thanks Tom!

/Niels

Hi again Tom!

I now switch to the HDQ mode on my EV-board in order to use the four LEDs for the SOC display, in a constant aktive mode!

I have the com up and running and the SOC are shown the correct value in the EV-software, but I do not have the right LED readout?

I have set the LED_Comm Config in the flash register to 0C (LED mode 2) as listed in the datasheet, but this set the wrong LED readout!

What do I do wrong?

Best regards,

Niels

Niels,
The sentence, "Bits 0, 1, 2 are a code for one of five modes. 0 = No LED, 1 = Single LED, 2 = Four LEDs, 3 = External LEDs with I2C comm, 4 = External LEDs with HDQ comm", is not referring to bits 0, 1, 2 ... in the register. Four LED mode with constant on will be command 0A. (bits 1 and 4) It would be set to 0C, when four LEDs with the external shift register and constant on.
Tom

Thanks Tom,

I can see it is working with the 0A command, but where is this described in the datasheet?

/Niels

Niels
The description is with the LED/COMM Configuration table, but the bit definitions can be confusing. External LEDs means using the shif register to drive the LEDs.
Tom

Tom
I need your support again!
I am making the same battery pack with a new 34z100EVM and have all up an running as last time, but have the same problem with the four LED bar. The SW shows correct 100% SOC but I have only light in LED-D and LED-C!

I have attach my config file and hope you can see if any setup problems cource this?

Hi Tom,

After reconnected the power and made a charge cylcle it works now!

So you do not have to spend time on my question above :-)

Have a great new year!
