Hi all,
I was wondering if anyone has any experience using the TDC GP21 chip from ACAM. I am working on a laser rangefinder project where this chip is used but we are having great difficulty communicating with this chip. We are using a PIC16F887 through SPI interface to read and write to the TDC chip, but we are unsure if we are actually writing anything to it because when we read we get data of all zeros. Any help would be appreciated. Thank you.
