Hi Josh, Let me give you my opinion: The memory of logicport (intronix) is of 2k points, but compressed. Only changes are stored. Considering about 20 transitions in clk, data and cs signals this 2k points can store aprox. 100 SPI commands. Its a fantastic advantage for a low cost equipment. You can analyze seconds of information limited only* by this transitions. Problem: Not too serious, but problem. The crosstalk is very high. The cables are not shielded and ground is only one pin for 8 data signals. You learn to indentify valid signals transition and crosstalk readings, when they happen, and its not a serious problem for SPI debbung in most common applications. Other problem is that SPI analysis is done only by software. You CAN'T use the SPI readings as tringger. For example, you can't trigger the system when a SPI value was receveid. But others trigger possibility make this problem smaller. Have you donwloaded the demo code from intronix yet? Try the software. That's all.
