ScriptGUI3, MC33777BT (EVBMA777T3) and BMA6402SA (KIT6X02AP2T1)

Hi,

I am trying to run some demo scripts in SCriptGUI3 (3.55) to read back registers from EVBMA777T3. I am using the KIT6X02AP2T1 to interface the TPL3. From the source code it seems that BMS6402 is supported, but the script (777_uc1_precise_current_meas.txt) doesn't work. Am I doing something wrong?

Hi,

in my previous post I listed the wrong file. I used SCRIPT_uc1_current_measurement.txt which should auto-detect the PHY, not the 777_uc1_precise_current_meas.txt. The output (error) is fine. I am attaching the file.

Hi,

I have spent the last day trying to run at least some example script from the ScriptGUI3 using KIT6X02AP2T1 and EVBMA777T3. Since that didn't work I modified the script to access at least some registers from the BMA6402SA gateway on the KIT6X02AP2T1.

I tried to init the PHY as bms6402 and as mc33665a as the device info register is the same. In first case I get a python error initializing the PHY. In the second case the initialization goes well, but I don't get back the response. Please see attached screenshoots.

What am I doing wrong or what is the trick using ScriptGUI3 and BMA6402 on KIT6X02AP2T1? In theory it should work. The kardware is fine as I can use the KIT6X02AP2T1 to interface BMA7118 using EvalGUI8.

Thanks
