attila Posted September 22, 2020 Share Posted September 22, 2020 Hi @eric_holtzclaw This looks like and electronic issue, ringing on the line. The AD Protocol I2C generates OD signals at the given frequency. Do you have common ground connection between the Artix and AD ? Do you have sufficiently low pullup resistors on the I2C lines ? You can enable the FreqFilter for reception under in I2C/Spy or under the gear after the "Clock stretching" option. This will filter glitches of up to 10% of the given frequency.
