 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. |

On a 470 Micromite running MMBasic 5.05.02, when the CPU is set to 5MHz, the timer and time$ functions run fast with time$ gaining about 11 seconds per minute. All other CPU speeds appear OK. Has anyone else seen this problem? Code below was used to test - SETTICK 60000, tickint CPU 5 DO LOOP SUB TICKING PRINT "Time is -", TIME$ END SUB Comparing with a known correct time, the MM thinks it is interrupting every 60 seconds but in fact does so every 48 or 49 seconds with the MM+ thus having the wrong time. panky. ... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it! |

That sounds like a serious issue. I will setup a test rig and report back. Geoff Geoff Graham - http://geoffg.net |
