HI MIKE,

Im using PIC24EP512GU814 a 16bit controller, im very new to this 16 bit controller. and what my doubt is, i cant able to identify the TX and RX pin of UART. but it having 4UART's. In the Pin out diagram i found PPS(Peripheral Pin Select) from that we can modify the IO's, but still i cant understand which pin is used for TX and RX. could you help me to identify the Pins of UART.

Thanks in advance,

Anboli.C

Dear Anboli,

Most of the Microchip 16bits products have "PPS" Peripheral Pin Select which allows to connect digital I/O pins to digital peripherals by programming (like an FPGA).

So at reset, the internal peripherals are not anymore connected to pins ;=)

You have to program how they should be connected. This is very flexible. You can even dynamically change connections while the micro is running !!!

Of course this is not so easy to do the first time, this is why there are many code examples.

At first, I suggest you read the Family Reference Manual related to PPS for your PIC24EP512GU814.

Then, to save time use the code example which shows how to setup registers to map I/O to/from peripherals.

In fact most digital peripherals will need to setup appropriate pins so any code example using a digital peripheral will have code to do that.

Go on the page of the PIC24FJ512GU814 and look for the code examples :

Have fun with PPS ;=)

Hi,

I am a new user of the Wifi G demo board (MRF24WG0MA) with the official source code example. Everything is going well in the softAP network type. However, when I tried to change it to Adhoc mode, it was not working i.e I can't even detect the Adhoc network on my list of networks on my laptop.

This is the only change I have made in the source code:

#define MY_DEFAULT_NETWORK_TYPE             CFG_WF_ADHOC 

Is this enough to make the example work on the Adhoc mode? Could you please help me to know what is going wrong exactly?

Thank you.

Best Regards,

Marouane

Hi,

I think you need to change more options than just the line you mentioned.

You may want to check the TCP/IP stack documentation in the libraries. Maybe some guidance is given which parameters to change.

The demokit documentation is here.

You can also to post a ticket to Microchip support or to the TCP/IP dedicated forum

Originally the AdHoc only was supported in the WiFi module firmware. Later, SoftAP support was added.

Is there any specific reason why you want AdHoc ?

SoftAP is much more "firendly" as it basically allows connections with all types of devices (any maker of smartphone, laptops, tablets,...)

NB : Android does not support AdHoc...

Hi Mike,

I have been an Digital design engineer for over 20 years, and I have been fighting a problem with a DSPIC33FJ256GP710 design for the last 3 months.

Now my boss has asked me to hire an expert for 2-4 weeks to help me resolve the problem.

Where do I look for an expert?,

or how do I look for an expert?

OK, I guess I can imagine a few of the How bullet points.

1) summarize the problem

2) identify 2-3 skill sets that would be required to resolve the problem

3) Search for the Expert

4) Determine which of the candidates will be able to do the job.

Given that high level summary, could you help me expand on points 3) and 4)?

Hi Burt,

Microchip has official design partners all over the world : http://www.microchip.com/partners

You can also use the Microchip online technical support : http://support.microchip.com

Maje sure also to post in the Microchip forums which have a large engineers community.

There is even a dedicated forum for dsPIC33

Another useful resource is training. There are webseminars / online training and also training centers in several countries around the world

Hi,my pickit2 crash when I try to start him,my OS is W7 and the pickit2 it works fine about couple years until now.I check the pickit2 with the same windows installed on another hdd and works fine,so pickit2 its ok,I guess is something wrong with detection or what,in Device Manager appears HID when I connect the pickit2 to USB.The error that i received from windows is "Pickit2 has stopped working".

Hi,

If your Pickit2 is detected as HID device it means from PC side it is OK.

The error message you see can be due to lots of different reasons but the number one is that there is some issue on your hardware side.

1/ wrong ICSP connections

2/ wrong PIC reference selected

3/ incorrect reset circuitry

4/ damaged ICSP on pickit2

5/ unsupported PIC

Best is to test the same hardware on another machine to make sure board + pickit2 are fine.

Using some tools like USBdeview you can remove the Pickit2 driver and plug it back so that it reinstalls

Which SW do you use ?

Pickit2 is a very old tool which has been released to open source community. It does not support lots of recent PICs. You may want to consider to buy the successor Pickit3 which supports are PICs ;=)

regards

I explain wrong the problem,I apologize.

The GUI is the problem,won't start,the GUI should start even the Pickit is not connected to PC.I suspect Visual C++ library or NetFramework.
