Can you tell what settings did you use saving data in decimal? Did you use atoi? I am looking for simple solution without atoi to plot graph from my data from UART on PC screen. I tried a lot of programs, only Bray terminal can plot, but relatively poor.
P.S. I have just done Excel program to plot graphs. In my ancient Ex. 2000, there are no hex to dec, but it was not very hard to implement. However, it takes time to save hex file in ComPort Toolkit and graph it.
