Hi,
I have a problem.
USB-TO-GPIO adapter is Damaged.
How can I configure and use the bq78pl114 without an adapter?
When reading any of the settings, I get a 0xffff, but ACK going to low. Why?
When I Read "Read Device Status" ( 3.2 in TRM) in Result: [Start] 0x17 (ACK) 0x80(NACK) 0xff(NACK) 0xff(NACK) [Stop]...
You can communicate to the PL114 without the adapter or bqWizard, but you have to follow certain protocols to unlock and setup the device to access information. We have an applications brief that covers SBData commands. It is available on the TI website by searching for SLUA591.
Thanks ThomasCosby.
If device LOCK, any read transactions will fail?
What is " setup the device to access"? I did not find description of this procedure? UNLOCK command does not help. :-(
I do not see address of "Algorithm Enable Register" in SLUA591...
The device will still ACK an SMBus transaction as long as the SMBus address is correct, but it will not use the data if the device is locked. the Algorithm Enable Register is not available through SBData commands. You can use API commands to access this register. API commands are a little more difficult to use than SBData commands. We have a API Demo tool available on the PL114 website to help with using API commands. You can see the SMBus data stream at the bottom of the screen. We also have an API User's Guide available on the web. (SLUU414A)
BQ78PL11X API Demo.exe requires the adapter.
I can not start "Connect" -> "Adapter Selection Error".
Library TI.bq78PL11X.dll works directly with USB-TO-GPIO driver?
Smail,
The TI.bq78PL11X.dll file contains all of the API's to control the device. TI.Communications contains the SMBus protocol information and TI.UsbHid.dll handles the USB transactions to the USB-to-GPIO adapter.
Regards
Tom
I can not run my device. :-( Using bq78pl114S8 and 4 cell config.
UNLOCK command accepted, but the read command does not work.
I understand that without using an adapter I will not be happy!?
The TI.bq78PL11X.dll library source code is available?
TI makes great chips, but very very poor documentation.
