Despite the bans and restrictions, some owners continued to rent out these properties. To encourage owners to return those units to the long-term rental market, some municipalities imposed bans on short-term rentals, while others applied restrictions on how they operate. When the federal government announced this change, it justified the move by saying that in Montréal, Toronto and Vancouver in 2020, there were almost 19,000 homes being operated as short-term rentals that could be used for permanent housing. The elimination of some short-term rental deductions was announced in the Fall Economic Statement (FES) and kicks in on Jan. GST/HST exemptions, the elimination of deductions for some short term rentals, new alternative minimum tax rates and changes to Canada Pension Plan (CPP) contributions are among the new measures coming in 2024. But tax experts say the effects on most individuals are likely to be minor, unless they're high-income earners. You can use several in the one ISR, keeps things simple and compact.New tax measures, and changes to existing ones, will begin affecting Canadians in 2024. I think I may add the RTC later as I can use it display date time on LCD without constantly spending time talking to modem and I should be able to read the time from the SMS modem to set the RTC.Īnd thanks JAM for the help on keeping the Timer ISR short & sweet and checking flags later. Thanks Jay, for the tip on the RTC and the count down point. Since the counter stops when it reaches zero, you never 'miss' the zero. If (for instance) you want to wait for 5 minutes, set 'count = (5*60)-1', and then wait till it is zero. #INT_TIMERx //whatever timer you are using #define TICKS_PER_SEC xxx //depending on your interrupt rate The key is to just check what you need to check in the ISR, and set flags so that the time-consuming tasks can get done in the main loop where time is usually not as much of a factor.Īs a general 'comment', depending on how fast the 'tick' is, and how fast the main loop is, I prefer to use 'countdowns'. The whole routine is very short and quick - simple compares and increments and the like. I then check it in the main loop if set, I call the housekeeping tasks I need to do once per minute, and then clear the flag. I have an external flag "doOncePerMinute" that gets set if 1 minute has passed. In this case, "upTime" is a global unsigned int32 variable that gets incremented with every interrupt (in this case every 100 mS). Static UINT16 ticksMinute = TICKS_PER_MINUTE It uses Timer0 to keep track of system uptime and also to trigger the tasks I want to do once per minute. Here is another simple example from some code I wrote. To address your concern, as long as you do as little as possible in the interrupt service routine (ISR), you will have no problem at all with that scheme. There's a nice software RTC program in the 'code library' here that would be a GREAT start for you!! Shows how to set/test 'flags' for hrs,min,day,etc. I'm using an 18F46K22 chip with a 16mhz crystal How long is it reasonable to set a timer/counter to ?Īny guidance or thoughts would be very welcome. I think the latter is probably the best way, but I'm a little worried about to many interrupts happening and using the timers is pretty new to me. Or should I setup the timer with a tick of maybe 1 second, and use an ISR to increment a 16bit counter and check it to see if it's over XX(seconds) and if so clear it and send the status message ? So can I setup a timerX with very long interval (like 5 minutes) and check to see if it over flowed whenever the loop got around to it. Checking the function would be in the main loop so depending on whats going on, the time it gets called could vary 1-20 seconds as it's a very low priority. It's fine if it's 10 minutes 30 seconds (or whatever) as it's just a status. Now that this is working I would like to be able to setup a function that will check to see if say at least 10 minutes has passed and if so send a general sms status message. I have a project that monitors equipment, does whatever based on inputs, updates an LCD display and also sends txt messages with issues. I'm trying to figure out the best way to have timing intervals in the order of 5 to 10 minutes. Please do not post bug reports on this forum.
