WebIIC ACK is effectively a violation of the IIC data transfer protocol which is used to signal receipt of a completed data block. Any spike is incidental. As long as you follow the instructions and meet timing requirements, when other signals rise or fall (to generate what might be seen as "spikes" is of no relevance. WebIntroduction. The Qwiic Differential I 2 C Breakout is the fastest and easiest way to extend the range of your I 2 C communication bus. The breakout uses NXP's PCA9615 IC, which converts the two default I 2 C signals into four differential signals: two for SCL and two for SDA. Coupled with the ease of SparkFun's Qwiic connection system, the ...
