Re: dsPIC PID Control Basics

Hi Guys, I'm back on this project start of next week and really need to make some progress quite soon. If you think the problem we are seeing, are just down to my FC code, I'll keep working away and try other approaches Just want to check the odd values I'm reporting are not bugs, before I commit mo...

Re: V7 PIC LIN Components

For myself, I would typically be looking to read existing LIN devices, manipulate and send data back out on CAN. So a LIN Master component would be most helpful.

Re: V7 PIC LIN Components

Just to throw my two cents in.. Sounds like my role is similar to Jonathan and as another engineer in automotive, LIN would be good. My last potential LIN project was unfortunately LIN2.0 and could not get the device to work with the V6 component. My typical PIC target of choice was/is the ECIO40P b...

Hi, My results are only from the SIM but. I've ensured, control, setpoint and feedback are all Signed Integers. The numbers show on sim are still not what I would expect; however... is what I am expecting correct!! :D If, I have a set point ADC at 128 bits (0-255), and a feedback ADC at 100 bits (0-...

Re: dsPIC PID Control Basics

Apologies for a blatant bump, I'm getting a better feel for some of the basics of the PID but still struggling to understand why the output values do not swing between the ranges I would expect? Regards, John.

Re: Long numbers

If .RANGE_OFFSET = ULONG .ADC_OFFSET = UINT .REF_RANGE = UINT To achieve this, .RANGE_OFFSET = .ADC_OFFSET * .REF_RANGE try, .RANGE_OFFSET = .ADC_OFFSET .RANGE_OFFSET = .RANGE_OFFSET * .REF_RANGE I found that to get the result of calculations properly applied to a ULong variable, you had to have a U...

Re: dsPIC PID Control Basics

OK, so if you change the DSP system components sign, to signed. You do get positive and negative numbers. I disabled the simulation 2nd and 3rd order responses, as (for me) they were just confusing the situation in simulation. I can see the values in Console and these seem to what I would expect. Se...

Alternative Zoom method for Dash and System Panel

Hi guys,
Using a laptop without a third button or scroll wheel, you cant zoom these panels.
Sure, laptops are not used for the bulk of development; but in the field not being able to zoom these panels, is a real pain. :(
Or am i being stupid an missed something?

What determines the base frequency in your example, is it the 1ms delay, i.e. how fast you Generate the 'tick' I would like to use the component as a quick way to output a pulse train. I c...

Re: MIAC Input Resolution

Hi Guys, Looking at the dsPIC MIAC for an upcoming project. The inputs are 10bit 0-12V, is that from a regulated on board 12V? Or is it just the supply voltage, so I may get input AD variation with dips in the supply? If I used an advanced MIAC module, to get 12bit 0-5V, what sort of rate is that sa...

Re: EB023 Internet Eblock - DC-DC Power supply 3.3v

Ok Thanks Leigh, I'll run with a Linear and see how we go. I suspect the EB023 E-Block designer wanted to use the 12V DC supply so as to not load up the upstream EB006 Linears's 5V supply.
When dropping from 12-16V to 3.3V..I guess the efficiency of the DC-DC make it a good choice. J.
