NilRTOS - A Fast Tiny Preemptive RTOS

I am trying the NilFifoDataLogger demo, but getting this when typing a char to begin, DATA.CSV is emtpy:

type any character to begin
type any character to end
type any character to begin

PS: maybe it is a high time to introduce a new item into the "Topics", ie. " RTOS" or something like that.. :stuck_out_tongue:
