Multiple macro imports

Hi matrix team, Recently I have been doing a lot of work with macros – developing large applications by reusing pre-existing macro functionality. In my latest project I had to import up to 30 macros. The current functionality (unless I've missed something, which is quite possible) you can only impor...

DSPIC MIAC digital input pins

Hi Leigh, Just doing some work with DSPIC Miac and simulation of the digital inputs I1 - I8.. Looking at the chip window in FC 7 I can't figure out which inputs I1 - I8 are mapped to the chip... Basically what I want to do is to use switches on the system panel to simulate the inputs on the miac for...

Re: 8 bit upgrade issue

8 bit upgrade issue

Hello team, I upgraded FC7 today to include the 8-bit pic chip pack. The purpose for upgrading was to make modifications to code that was previously generated in FC 6 for miac V1/V2 The first time I tried to compile to the miac device – compiled to C but froze on the next step. Hit the cancel button...

Hi jaydee, This looks very much like an industry based IEEE 754 format....your in luck as I have written a conversion macro for the new dsPIC MIAC in FC7. this shold be transportable across the pic range..

Re: Load Cell HX711

Hi George,

I used 4 load cells from a bathroom scale I purchased for $25...very cheap and cheerful

4 cells wire in a Wheatstone bridge config is good for 150kg with a resolution of 1 gram (ish)

Can you describe what not very good means?..do you know the scaling factor?

Re: Load Cell HX711

Hi George, The fluctuation is pretty normal to a degree - hence my reason to suggest an averaging methodology.....Also check your PSU - do you have filter caps close to the HX711 Chip/board?... this can be a source of noise... The other thing you can do is reduce the gain and scale up... this may al...

Re: Load Cell HX711

Hi George, Attached is a macro is created in fc6, it will also work in fc7. It reads 24 bits of data from the hx711 chip....the project I used this for was a 4 load cell scale connected in a Wheatstone bridge config. Import the macro into your project and call it as a routine. Note - given the sensi...

Re: Gas flow meter/pressure and O2 measurement

Hi Giovanni, I would recommend that your starting point is to find industrial grade sensors that are suited to your task. For example the difficult bit is usually physically interfacing the sensor into the plumbing (pipework) of the system that you're trying to monitor. Given the industrial solution...

Re: DS3231 - RTC Time Keeper

HI Jordy,

I have been looking at your component for the DS3231 that you posted some time back. Would it be possible for me to get access to the source so that I can update it to drive a DS3232? this is a later version RTC

Happy to post back the updated version on the forum.

Hello team, I think I already know the answer to this....does the RXINT interrupt simulate in FC6? If not is there a work around to simulate other jumping to the macro from the main loop?
