Hi Ben☺

Thanks for clearing that one so quick for me ☺.

Best regards

Hi all. I recently discovered that the above mentioned component(RFID_MFRC522_V2) is no longer remappable? If I choose for example ch 2 then all com pins are locked to RG6-RG7-RG8. but pin SS and Reset can still be remapped. My target: 33EP512MU814 Is this a bug or done by purpose? Best regards Nick

Hi Ben. Thanks for your answer :-) I changed my target MCU from 24EP512GU810 to 33EP512MU810 And now it`s working beautyfully :-) so thanks for the tip to just change tartget device. By the way, have you had anything to do with 33EP512MU814? just asking since my next project propobly will involve mo...

Hi all.

Did anyone look into the problem remapping UART?
I was intending to use modbus slave component yesterday but it still has the above mentioned flaws it seems...

Edit.
My target is : PIC24EP512GU810

Hi Ben.
....
I cant belive I just didn´t see that

Thank you for, as always, excellent support Ben

Hi Ben.
Thanks a lot for looking into it, maybe I´m just not seeing the problem.

I have tried it on hardware.
Here´s the file

Hi all.
I have been trying to use a PWM component in a project but no matter what I put in the duty cycle it always stays 50%, Has anyone else experienced the same thing or am I missing something?
Have tried both 10-bit setting and 8-bit setting and the result stays the same...50%

Hi all. Thanks for all the feedback, I´ll try too describe the problem. I have a client that currently are using an RFID tag/card passage system designed by me and it has been working prettu much ok fore a couple of years, but now the RFID tag/card doesn´t provide a high enough security level anymor...

Hi Ben.
Thanks alot for the quick reply.
I´ll give it a try and post the result here later.

Does anybody know if the fingerprint sensor, mentioned above, ever were implemented in FC7? Or am I just blind and can´t find it?

Another update, the modbus slave component are receiving on all 4 channels but it doesn´t transmit anything on any chanel, I have tried almost all pin configurations.
Any ideas anyone?

Hi Ben. Ok I´ve done some moore testing, Port F is not sending(TX) anything at all no mater what I try, Pin G0 and G1 are sending(TX) on HW chanels 2-4. Port D lower byte is working on chanel 3-4 not 1-2, port D upper byte doesn´t send anything on any chanel. Chanel 1 doesn´t seem to do anything muc...

Hi guys. I am trying to use the modbus master in a project, but when I try to remap TX RX to for example F.2 and F3 those pins become completely dead on my HW? The only pins that seems to work are G.0 and G.1 and it takes a lot of fiddeling to remap to those again, including chaning the pins in both...

Hi Ben.

Thanks for your reply, and your suggestion is spot on what I´m trying right now, I´ll post the result here when I´m done.

Hi all.
Would it be possible to use the bluetooth component HC06 in FC7 to connect, for example, an Android device and use modbus rtu protocol?
Has anyone tried already? Any ideas on how it could be done?

Hi Leigh.

I just did the last upgrade of 7.3 and after some testing it seems to work in both HW and SW mode, so I guess its working, I will use it in a project later on though for proper testing.

Thanks a lot

Hi all. So I`ve been trying to use the I2C Eeprom component without any success, has anybody else used it since upgrade 7.3? It compilates ok, but when running the program it stops in the Read command. The MCU speed seems ok after running the "blinker test" at several rates and also PWM ch...

You could use a suitable IC for the job such as: LM1815. it translates the sine to a nice clean TTL signal that can be captured by your PIC, I have used this IC in automotive aplications and it works like a charm.

Hi Ben.

Will you make a list of wich decvices you find? Since I have had some problems with dsPIC33ep512MU810, perhaps something similar to the mu814 issues.

Hi Docara.
Sounds like you need a pwm output and an RC filter(a resistor in series and a capacitor in parallel) after it, and by varying the dutycycle you will have an analog outputsignal.
About the values of the filter, it depends of how fast you need to alter the outputsignal.

Ah ok...

It is more or less the same deal for me as well, I´m still using FC4 since FC5 doesn´t seem to support the RF component...

Hi Andreas. Did you ever receive any help for your problems with these RF modules? Cause it turns out I have the very same problem. In FC4 everything works just fine, no problems, but when compiling the FC4 code in FC5 nothing works, not even disturbance. What is even stranger is that if I rewrite b...

Hi Ben

Ok I´ll try that straight away.

Thanks alot Ben

Hi Ben.

Thanks for your very quick reply, the main problem is not the missing 2Hz but the lack of coms with the RF unit, I just thought it may be related someway.
Sure I´ll post the program but all it actually does is; send a byte and wait a sec.

Thanks alot Ben.

Hi everyone. Has anyone made a design/program using 18F8627 succesfully? I have been trying to make it work @20MHz but there seem to be some oscillator problem, if I make a loop with a 2mS delay and toggle a port pin I get 498Hz! Tried to compensate this by reducing the oscillator speed in projekt o...
