Very helpful, thank you!!
Using the RxInt for data capture solved a lot of issues for me.

Hello Ben,

With the CAL file from 2 June 2020 AN16 simulates but does not work in the real world once compiled, I will check them all with the latest CAL over the weekend and let you know.

Why is the speed for this device limited to 48MHz, it is a 70 MIPS machine and according to Microchip, it is ...

Quick Fix, if you have a backup
I replaced the (01.06.2020) CAL folder "C:/Program Data > MatrixTSL > Flowcodev8 > CAL" with a backup copy of the folder (09.04.2020) and it has fixed the compiler issue with the dsPic xx EV xx's analougue channels not working.

dsPIC33EV256GM106

My FlowCode 8 updated on 1 June 2020 now if I compile some of the analog channels don't work but they simulate fine.
If I load the pre-update compiled HEX file of the same program it runs perfectly and all the analogs works?
I have reported this before and the FlowCode team fixed ...

Hello Ben,

I apologize for the long wait, I have been traveling / working on site.

The reset problem was caused by the "Dead Man Timer" ( _FDMT ) it is set as default Enable in FC8 -> Project Options -> Configure, if one is not looking for it specifically it is easy to miss.

Ben,

I have a problem with the dsPIC33EV256GM106 resetting, I have tried to fix this by inserting the "MX_CLEAR_WATCHDOG", switching it off in config, Auto WDT [ON] and also setting the WDT window to [None]

It happens at 5min intervals with 48MHz crystal and 12min with 20MHz crystal - this is why ...

This is how I initialized and used the advanced high-speed PWM module with FlowCode8, thanks to QMESAR for pointing me in the direction, the various configurations and setup of IOCON, PWMCON, PTCON and FLTCON is available in the EV family datasheet.

Ben,

Thank you, the analogue channels all works very nicely now!


Kind Regards

Ben,


If we only have the basic CCP available how does one go about firing two pwm pulses one on the rising edge and one falling edge interlocked with a 20kHz clock, please see attached diagram.

I have spent hours and hours on this with no success.....

Ben,


Thank you, it has been a long day, I will test it in the morning and let you know

Ben,

My apologies for the PWM Pin assignment table, herewith a understandable one

Hello Ben,

Further to the Analog issue, I decided to commission the digital side of the system while we are talking about the analog read issue but I am having problems with the PWM configuration with dsPIC33EV256GM106 and Flowcode 8.2.1.13. Is it structured as option 1 or 2 below?
Why does the ...

Please help

Flowcode 8.2.1.13 / dsPIC33EV256GM106-I

In software Flowcode simulates reading AN0-19, AN25-31, AN41-56. The hardware chip only reads AN0,1 none of the others are read.

We suspect PIC16bit_Cal_ADC.C has not been upgraded correctly to accommodate the EV series but is set for the ...

Ben,

Thank you very much!

I got the update, it works, I will start using it today





Kind Regards

Ben,

Thank you! Having the EV device would make the design much easier as I don't have to level translate everything this takes up so much space on the board.


Thank again

Michael

Hello,

Does Flow8 have a boult-on for dsPIC33EV64M004, this is a 5V dsPIC and I cannot find it in the device list?
