 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

HELLO!  
I have the duinomite mega and I have been trying my best to conduct a frequency count. I have tried everything and I am ready to give up on this board :( I have plugged in both a wave generator at 3 to 5 volts as well as a fez panda and arduino into pin 11. Nothing else plugged in. I have then typed [code} 10 setpin 11,5 20 for i=1 to 100000000 30 print pin(11) 40 next i [/code] It just runs and runs as 1111111111 The funny thing is that when I setpin 11,2 I can see the wave as 111000111000111000 I need to count increments less than 1 millsecond and I was going to do this with the sound out. This board is plenty fast enough to need a counter less than 1 millisecond. |

Hi Rob, Which version Firmware are you running? If you have Geoffs port of MMBasic installed I dont know which pins are compatible for frequency Input. If you are using the OLIMEX version the correct pins to use are Pins 5,6 or 7 I am making the assumption you are running the OLIMEX version here, (as I dont know off hand which pins are to be used in Geoffs 12 pin IO port to DM.) To read a frequency the pin should be set using SETPIN 5,3 SETPIN 5,4 is for PERIOD SETPIN 5,5 is for count If these dont work flash a later firmware, see list HERE Regards, Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |
