In SensorPowerSequence, what does the value field imply?

Hi,

Could you please share which platform do you use? OMAP5432 uEVM, DRA7xx EVM ?

Which sw release do you use?

Thanks,

Yordan

I'm using OMAP5432 evm.

I'm using Panda 5AJ.1.5 Release notes.

Hi Gomathi,

 Can you specify also for what kind of sensor you are making the sequence. As you understand the transition/ level and interval time is different for each sensor.

For example:
{SEN_PWR_CMD_XSHTDWN, 1},{SEN_PWR_CMD_DELAY, 5},{SEN_PWR_CMD_XSHTDWN, 0},{SEN_PWR_CMD_DELAY, 5},

For Toshiba Bridge TC358743.

Hi Gomathi,

Unfortunately I don’t have access to the suggested signal sequence for that bridge nor I have seen example for working SensorPowerSequence for one such device, meaning you have to follow the recommendations in its data-sheet, and thinker with the delay values and the sequence of the signals. Having a working sequence for a typical sensor may prove usefull for reference, but i suggest to follow the recommendations in its data-sheet.

Thanks,

I just generally like to know, what those values mean? Not even specific to a sensor. What is a 'value' which we provide along with the command, generally ?

Well it is simple as 0 and 1 to the appropriate signal name. For example some sensors have XSHUTDOWN  input pin, which is specifically required to be toggle on specific place in time in order the sensor to initialize correctly.

XSHUTDOWN pin is a GPIO pin. So, can I interpret the sequence as,

Toggling it to low first and toggling it to high again?

exactly 

( and also the delay between the events)

Thank you!!!
