Hi,
today im trying to make the TPIC to work. Can somebody help me how to configure it in TS? I think the problem is there. What about the connection the connection is 1:1 as the frankenso .4 pcb. Im getting nothing out of the tpic, i am using signal generator 4Vpp 8kHz on input.

On the forum and in the code base we usually mention it as hip9011 - please search for hip9011 and go over all topics. http://rusefi.com/forum/viewtopic.php?f=4&t=400 and http://rusefi.com/forum/viewtopic.php?f=5&t=778

Really painful subject, three years of head banging now?

I suggest using rusEfi console since it has a few helpful commands. See https://github.com/rusefi/rusefi/blob/master/firmware/hw_layer/HIP9011.cpp for altimate details.

What is your hipinfo output?

This is my output of hipinfo in console

EGT sensor hangs on SPI3 and is fully working, so the two SPIs are enabled.

That's a good start! At least SPI seems to be fine.

In these two older threads there are videos of oscilloscopes on the output, can you make a similar video? Would we at least see some zigi-zaggy?

Also I believe touching random hardware parts was sometimes helping

Yes, that is what i thinking, something in input stage goes wrong. I will test it. I have the Int/hold inputmode as default inverted, and the CSPIN input mode also. Is not that the problem?
The command enable tpic_advanced_mode toggles the internal ADC reading or STM analog input? So if i use enable tpic_advanced_mode 1 i can ignore the STM analog input?

I personally have no recollection of any sucesses with tpic_advanced_mode - I was only using analog output.

I've pretty much just posted all I remember about this topic, as I said quite some time ago and quite a depressing subject. You need an oscilloscope and your turn to band yout head a bit, I hope you would be able to move this sore issue forward!

Looks like default for prescaler is
hip9011PrescalerAndSDO = 6; // 8MHz chip

Problem is solved now. The INT/HOLD pin is not internally pulled high, but its pulled low! That was the failure. Now it works.

Please elaborate, what works exacly? Does frankenso schematics have issues?

When i designed my board i looked into the TPIC8101 datasheet and all SPI lines and CS have pullups, but i have not read correctly that the INT/HOLD is internally pulled low. I did not placed a pullup for the INT/HOLD. It seems that the 3.3 high logic level was not enough for the TPIC. Now it works. On Frankenso board there is R170 for the INT/HOLD line designed.

Good to hear you got it running, also good to hear this is already done in the Frankenso layout.

Please keep us posted on your progress! I would love for someone to step in and move this area forward.

Stay tuned. I am making steps forward as i will now have some "free" time to move forward with my car. Summer is near and the car must be driveable at summer.
