Description:

ibeen stugling for 3mmnths and submission of output is near .my wemos lolin is working find in any file example in arduino ide.. im really sure that i installed properly the esp 32 to arduino ide.. my problem is when im uploading the sketch of my xgzp 6867 pressure sensor . "im getting error compiling sketch for wemos lolin32".. or just dont write it the right . please corrrect my sketch on how to compile it in my wemos lolin 32.. thank you in advance.

//Change the code below by your sketch

This example code is for a bit bang'd i2c interface. The esp32 has builtin hardware to handle I2c. It would be better to use it.

Do you have a link for the datasheet that contains the I2C commands for your sensors. I was unable to find one with a google search. All I found was the hardware spec, no listing of i2c commands or data fields.

If you can show me the command list I can help you communicate with the sensor.

[Bryanbaring]

i will ask for my dealer sir.. i post it here soon

[Bryanbaring]

@stickbreaker seems the supplier is sending me the same files and insisted that it is already on the same files i sent ..is there other idea to find a way how to deal with this sensor sir ?

[beegee-tokyo]

Is this the datasheet ?
Nothing about I2C commands there but did you try to just read 24 bits (resolution mentioned in the datasheet) from the sensors read address?

[Bryanbaring]

@beegee-tokyo .sir can you help me on how to code this thing sir.. all i have done is fine the adress of the device and the address is "6D".

[stickbreaker]

@beegee-tokyo Yes, shitty datasheet. the posted bitbang code show a possible configuration sequence and readout. I thought I would try to reverse engineer to something understandable.

the datasheet show the ID as 0x6C or 0x6D but, no protocol info? What the F?

Chuck.

[stickbreaker]

@Bryanbaring Try this test code xgzp test sketch

Chuck.

[Bryanbaring]

@stickbreaker This is the result from the serial monitor that showed up.
What should I do next, sir?

[stickbreaker]

@Bryanbaring
Wire.begin(21,22,100000) in setup().

After that, if my test code doesn't work, then it is a protocol problem. (Documentation needed)

Chuck.

[Bryanbaring]

@stickbreaker
huhuh the same result..
Reading from 0xA5 failed =(timeout)
Init of sensor at 06D Failed

[stickbreaker]

@Bryanbaring I2c is working, but we have a failure to communicate with sensor, so that is as far as I can go without additional protocol information from sensor manufacturer

Chuck..

[Bryanbaring]

this is the ic that they used for this sensor

CFS 2300+Datasheet+Rev1.9_2018.pdf

[stickbreaker]

@Bryanbaring That datasheet makes more sense. I'll look it over and see if I can figure out an example to communicate with the sensor. It will take a few days. Probably by next week end (feb 16).

Chuck.

[Bryanbaring]

@stickbreaker
ok sir ill wait . thank you very much. .

[stickbreaker]

@Bryanbaring ReWrote test, try it xgzp.ino
