Happy New Year ! Thanks for your info, and I did get the Pmod Tof to respond and give me distance data. But the output is not steady and that may be because I have not calibrated it yet. So I have 2 questions: 1) The provided information says the "User calibration is 13 bytes, but it doesn't specify where, within the 16 EEPROM bytes, those 13 bytes are. I figured out that the first byte at 0x01 is the so-called "magic number" (whatever that means) so I assumed the 13 calibration bytes occupy the next 13 addresses, starting at 0x11. My second question has to do with the "Magnitude Calibration Procedure". When I implement that procedure, I stop getting distance data out. And the problem appears to be that the data at 0xF6, 0xF7, 0xF8 is always 0. So, the question is, are those addresses correct, or am I doing something wrong. Probably the "Magnitude Calibration Procedure" is the only one of the 3 that I will be able to implement. Thanks again for your help, Chris Kilian

It is drawing a small amount of current (my power supply has a current meter), so it probably is "alive", and I can see on a scope that my software is sending the right address (ae) but I only get zeros from any register I try to read. At this point all my software does is send a high and then a low to the SS pin, and then go into a loop reading the 0xd1 register (presumably the "Distance Output"). Also, it never draws anything more than that minimum current. Are there any other "set up instructions" I need to be sending?

I am trying to get my new Pmod Tof board working with a Coridium processor board using their BASIC which has i2cin and i2cout instructions. So I am not using pre-written finterfacing software. But my first problem is that it seems to be drawing absolutely no current. Does that mean the board is defective, or would it draw no current if it simply is not being addressed properly? The manual states its 7 bit address is 0x57, so I am sending oxae. Is that right?
