Hi TS.
You do not need to update all your devices with bqstudio and bqstudio is not just a tool for the EVM. You can connect your boards to bqstudio if you have an ev2300 or ev2400.
bqstudio will allow you extract a flash stream file, either bqfs…
Are there any bash scripts that one could use to program the bq27520-G4 chips in "production" units. If we decide to change the batteries in middle of production run what is the best way I can program calibration data for the new battery.
I wouldn't…
Hi All,
I'm using omap4430 based custom board. when i turn on the board, some distorted coloured bar is coming when home screen comes up. the LCD resolution aspect ratio is 854/480 = 1.779
#cat /sys/devices/platform/omapdss/overlay0/* 1 255 854,480…
hi Brett,
Programming of the gauge is done in ROM mode. The address of the gauge in ROM mode is 0x16, hence the reason you see each line starting with 16. In firmware mode, the address is 0xAA.
pls review the attached app note. It describes the commands…
Hi Adam,
I looked at the report and the criteria for determining a match for the rom gauges is not listed on there. The criteria is 5% in ROM gauges and our old matcad tool had provisions for that. Do you have a matcad license to use the old mathcad…
1. No the device does not support current, voltage and temperature self calibration. You need to perform those.The device only performs couloumb counter calibration before it goes into sleep mode to prevent drifts of the coulomb counter from occuring…
Hi Anna,
1. The accumulated discharge is calculated by column interger of current.
2. About Qstart, please take this document as referenc.

Hi Anna,
1.FCC is not reaching the design capacity.Why is it so?What is the calculation used to find the FCC during the first insertion of the battery?
FCC=Qstart+PassedCharge+RM, it will updated during the discharge and charge cycle. When first insert…
Hi,
see below documents as reference.
The second ducuments will tell you what register bit should be set when parameters have updated.
