Hi! Novelda. I use X4M03. 1. Matlab example : XEP_X4_plot_frame 2. Pyrhon example : simple_xep_plot2 3. RasberryPi example : x4driver_raspbian (I used a data_frame_normolized value to draw a graph.) I am working on a setup consisting of the X4M03 and RasberryPi3 B (instead of XTMCU02). Unlike Matlab and Python, x4driver_raspbian frame buffer size is 346. What is different result and graph? Sorry, I'm not good at English. Thank you.
