Re: Logic help - Ignoring short pulses

Hello Martin & mnf Below is a short depection of what I am looking to achieve. This is basically a signal coming of of a comparitor. I had the raw signal going through a low pass filter before entering the comparator but I was adding too much delay on the filtered signal. So I reduced the value of t...

Logic help - Ignoring short pulses

Hello I have spent far longer on this issue than I really should, it seems so simple but I cant seem to get it right and I seem to be going round in circles. I have an IOC pin that I need to use to time the length of high and low puslses. I am increasing a variable in a timer between any changes on ...

Re: Not compiling into new micro controller

Hi Leigh

Please can you let me know when I can perform the update without needing to add the file again?

Thanks

Re: PWM on one channel also shown on disabled channels

Quick update So, the duplication of the PWM on the other channels is down to hardware as you have suggested... thanks... To test it I just soldered a PIC to a new board with only athe bypass caps, crystal and its caps and the other channels look clean. I will look at updating the design with some pu...

Re: PWM on one channel also shown on disabled channels

It's difficult to get the schematic as this is only a very small section of the whole design. I understand the theory on using bootstraps (which I am in this case IRS2011). For both thte the high side and low side there is a direct connection between the PWM output of the PIC into dhe driver, betwee...

PWM on one channel also shown on disabled channels

Hello All So, I have a PWM on channel 1 on the dsPIC30F3011. This gives a next signal. However when I take a scope to the other PWM channels (even though they are disabled) I get a scalled mirror of the signal. The IC works from 5V and the PWM coming out of the disabled PWM is around 120mV (see pic)...

Re: Not compiling into new micro controller

Hello Leigh

It just does not seem to be my day today...

I copied and pasted teh location and relpaced the file.
I then re-started FC8, saw the update, downloaded update and re-started again.
Compiled the program again, and tested it on hardware.

The PWM is still coming out of PortD

Re: Not compiling into new micro controller

Hi Leigh

I have had to put it into a differnet place C:\Program Files (x86)\Flowcode v8\DefaultData\FlowcodeV8\FCD\PIC16 but it does not seem to be working. IS it in the wrong location?

I have re-started FC8 as well, but the PWM is still going out of PortD

Re: Not compiling into new micro controller

Hmmmm, I have just taken the scope to all the pins around the micro. It seems I am getting a PWM output at the correct duty cycle but on the wrong pin. I did not know there were re-mappable or alternative pins for the PWM's... However, the PWM is coming out on EMUD2/OC2/IC2/INT2/RD1 which seems a li...

Re: Not compiling into new micro controller

Hi Leigh OK, so when I change from channel 6 down to channel 3 I can now compile. But I think I am missing something. In simulations the PWM works OK but I get nothing on the hardware when I just enable the PWM and set a duty cycle. I have tried fiddling with the configuration settings, but still no...

Re: Not compiling into new micro controller

This happened a little while back with a different micro and Ben managed to doing an update on V8.1 to get it working. (I am using Channels 2, 4 & 6...

Re: Modbus Slave

Hello

I'm the second post above I have compiling issues when I use the RS485 bus and set the data direction pin.

I am using the dsPIC33EP32MC504, does anyone have any advice on getting this working? I have filled in all the component proporties.

Re: Not compiling into new micro controller

Hello Martin Yes I have noticed this, but I need 3 to work on this project. How can I get access to the other PWM's? Can they not work with flowcode at all? (and why is there a drop down menu for the option to choose 6 channels?) I dont need to do anything too complex with the PWM and only need 8bit...

Not compiling into new micro controller

Hello I have receindtly redesigned a PCB and needed ti change the micro on it to one of the slightly newer ones PIC16F15323 from a PIC16F1503. I need 3 PWM's on the program which worked fine with the 1503 but for some reason when I transition over to the 15323 I get the compiling errors below. I hav...

Hi Ben Yeah, I knew this. I was just hoping to keep the 0x00 registers blank and start from 1. The problem I am having is that if I request the data from register 1, I get the data from register 2. And if I request the data from register 2 I get the data from register 3. The data I have stored in th...
