while(1) { tom=(long)TBC(); if((tom511)) { dis1[2]='b'; dis1[3]='a'; dis1[4 ]='d'; } dis1[0]='w'; dis1[1]='d'; if((tom>=0)&(tom511)) and if((tom>=0)&(tom<=511)) mean? Why do we use them this way?...
F5438 seems to be better than F5529. Because I used G2553 to write programs before, but I didn't use the IO port for a long time, so I want to try other chips....
RTD Circuit Design
PT100/1000 meaning
Common RTDs are PT100 and PT1000. 100 and 1000 mean that when the temperature is 0, the resistance across the two ends is equal to 100ohm/1000ohm.
When the temper...
