PIC24FJ256GL406 chip on FC7 or FC8

Hi, Due to the chip shortage (and other unmentionable reasons), a shed load of PIC24FJ256 GL 406s were procured instead of the PIC24FJ256 GA 406 that we use as standard. Both FC7 and FC8 do not support the GL version. Is there some way to "cheat the system" to get code for the GA version onto the GL...

Re: Ghost not active on BL0032

Hi Ben, Thanks for getting back to me. I'm running 8.2.2.16 on the laptop and 8.2.1.13 on this desktop. Yes, I did a complete FC7 reinstall on the laptop last week and applied the fixes at that time, and have now applied then here too. The fault remains in that when the BL0032 is connected the ICD a...

Ghost not active on BL0032

Hi, I am not able to get Ghost, on a BL0032, working on FC8 so I've reverted to FC7.3.0.7. The problem experienced here is that the Ghost feature isn't recognized, i.e. ICD and ICT icons are not active although the BL0032 is recognized as the target and it is possible to download a hex file to the P...

Re: Bad mistake in FC8!

Hi, I stopped using FC8 for most of last year because of the Windows 10 shutdown problem. I started using FC8 again on Tuesday and experienced the problem on Wednesday. I was on version 8.2.1.13. I loaded 8.2.1.14. but I see version 8.2.2.15 is available. Can you supply a link to the new version ple...

Problem with Ghost running on BL0032

Hi, I'm using FC8.2.1.13 (with latest updates) to program the PIC on a BL0032 16-Bit dsPIC programmer using the BL0032 as the target. A simple flowchart consisting of a LED flasher and a "Hello World" compiles, loads onto the PIC and works as expected, i.e. LED flash timing and baud rates are all go...

Re: RS232 data corruption

Hi Martin, Yes, I misunderstood the alt pin usage, but included it in the test because it was there. I think there are still many little (or big?) things that I don't understand about the intricacies of FC.

Re: RS232 data corruption

Hi Martin I hadn't even thought about doing that sort of adjustment. I'll get hold of an oscilloscope and give it a go. The confusing thing is that I've done several projects using FC (all of which included serial comms) and so far haven't experienced any baud issues. I'm seeing the current problem ...

Re: RS232 data corruption

I'm using 9600,8,N,1, no flow control.

Unfortunately I do not have an oscilloscope available.
BTW, I forgot to mention that a "Hello World" gets through to the terminal emulator just fine.

PIC24 Internal CLocking

Hi, I would like to run a PIC24FJ256GA406 at 96MHz using the internal FRC Oscillator with PLL. One issue is that FC7.3.0.6 will not allow a Clock speed(Hz) setting (Build\Project Options\General Options) of anything above 32MHz, for this PIC. As the datasheet states that the "default divisor of the ...

Re: PIC24FJ256GA406 UART Rx Interrupts not working

Hi Ben,

I've used the new CAL file and channel 5 now works the same as channels 1 through 3. I unfortunately can't test channel 6 just yet, due to the set up of my PCB, but will let you know if I have any problems.

Thanks for the fix.

Kind regards.

Re: Using SPi Master (EB013) and TCP/IP (Wiz810MJ) Components - Feedback

Hi, Some feedback on this issue. The problems experienced were caused by the buss select chip U3, a SN74CB3Q3257, on the WIZ810MJ module. With this IC removed and the SPI lines connected through, Flowcode has no difficulty, whatsoever, in reading reliably from both Eeprom and WIZ810MJ SPI devices on...

Re: Wiznet WIZ850io module

I think getting the source code for the WIZ810 component would be a great starting point. If you could let me have that, I'll give it a full go and hopefully be able to contribute to the User Component forum soon.

Using SPi Master (EB013) and TCP/IP (Wiz810MJ) Components

Hi,

I am using the SPI Master (EB013) and the TCP/IP (Wiz810MJ) components to communicate with different SPI devices on a PCB. Could this potentially cause some communication problems?

I ask because I am experiencing some issues that I can't explain.

Hi Leigh, Thanks for the reply. The EEPROM is a 6-lead SOT-23 device which physically does not have the Hold Input pin or the Write-Protect pin, I assume this is taken care of internally. All other pins are connected and being used. I have done a bit of a work around in that I now do a soft reset at...
