Hi Martin Thanks for this. The project has some what progressed since writing the last post, I have now moved on to using the 33EP64MC206 for the addtional speed an IO. For this part the datasheet says it has a REFCLK0 that is remapable and easily set within the RECOCON register. I have never re-map...

Hi I want to run the 18F66K80 at full speed (64Mhz), preferably using an external Xtal (but could use the INTOSC if need be), but I also want a CLKOUT at preferably 5Mhz (but could possibly push all the way up to 16Mhz) to run a few external components in sync. Is this possible? I'm a little confuse...

Hi Ben The program in the first post was just a standard flasher program, and the timing is perfect. The C-code is needed to set the frequency up to 120Mhz. I have also disabled the interupt, and then repeated the flasher with no delays and observed a frequency (of the flash) of only just 30Khz. Tha...

Hi guys Any help on this? I have just tried setting up an external clock input into INT1, however it seems I cant get passed around 10Khz interrupt. My target at this point is to perform a few calculations every 60Khz fairly accuratly... Thanks EDIT: Just another note - I did a program on hardware t...

Hello All I have a simple program, I am trying to use a timer interrupt (Tried all 1, 2, 3 & 5) at a high frequency as a fairly accurate timer. But whenever I change the frequency it seems to affect the primary clock on the crystal (even though the clock source for hte interrupt is set to the Intern...

Sorry, My appologies for this...

It seems the original program was done in V6, not V8... Everything works fine when I recompile in V6...

Thanks

Hi Everyone I have a program which needs to be modified which I originanly did back in January. However, it no longer compiles. I am using PIC16F1508 and changed the internal oscillator speed in the osccon register to 0x7A using a C-code component in the original version. Now compiling it gave me er...

Hi Ben, sorry its taken so long to respond: This will largely depend on the micro your using and the speed the micro is running at. Typically the faster the micro is the harder it is to generate the slower baud rates. However, let me know your current setup and I'll investigate the code is being gen...

Thanks Ben

I have stripped the program back to bare basics, I now no longer even have the input pulse but still getting a strange output. FC program is attached and the output is below.

Thanks

Hello Everyone I have run a Modbus RS485 slave program a while back, and in general seems to work OK but I have found some problems (perhaps bugs) that I need resolved if possible. 1 - When I change the baud rate to below 9600 the communication breaks down. Works fine with all other baud rates I hav...

Sorry to push

I have shown the ADC is the affecting the IOC, so how to I stop it from doing it?

Thanks

Thanks Ben & Stefan Yes, its looks to be the analogue input! How/Why is the analogue input affecting the IOC though when the analogue input is is the main program? Will the anlalogue input (RC4/AN20) still affect the IOC on RC2 just because its on the same port? I am guessing I need to change RC2 to...

Hello All There is a part of a program (in FC8) on a 16F18344 where all I am doing is using an IOC pin (C2) which just has few pulses coming in. All I am doing is duplication this pulse onto another pin A1. However, for some reason I am getting very short drops in the positive pulses, anyone have an...

Thanks Martin
Worked great, implemented well in the SPI

Most probabbly the longest time I have ever waited for a windows update!!! but yeah, I did the .Net and then the additional optional updates and V5 now starts without a problem.

Hi Everyone

Same problem... I can open a new project without any issue, but when I try and open a project I did years ago it jsut closes down on me. Same as martin - been adapting V5 programs on this PC for at lease a few months with no issues.

Hello Martin

I apologise for not responding sooner - I was side tracked onto a different project.

I will take a look at your example later today

Thanks

Hi Martin

Thanks for the responce.

I have gone through all the options, I think the best option would be the shift and add method. I am still confused however how this coule be implemented in flowcode - is it possible you could do a very quick example?

Thanks

Hello All If it have an int, say 113, this gives a binary value of 0b01110001. If we count the 1's we get an even number - but how do we impliment this in code? I currently have an address of 5bits (say 10110), a data length of 10bits (0b0001110001) and the last bit needs to be the parity (needs to ...

Hi Ben

They were £10 each off Ebay... May be problematic, but was the only place I could find them at the time with the 16pins. I have now found some on RS components, I have ordered them. I will let you know if its resolved.

Graham

Hi Ben

Just to make sure...

Do you want me to change the F5 or the V8 RawSend .c file?

Then do I need to use the RawSend function on the LCD macro?

Thanks

Hi Ben

Sorry to push, but I need to try and get this resolved. Do you have any other idea's I can try? I am under a little bit of pressure to get this resolved.

Thanks

Hi Ben Unfortunatly the Fix for V5 did not work, I still had the Japanese charactors. With V8, I did a hello world and then ran it on hardware on both display types. I have attached the program and below are the pictures. WhatsApp Image 2019-07-24 at 16.04.37.jpeg WhatsApp Image 2019-07-24 at 16.06....

Hi Ben

Switching to Channel 2 and re-mapping the pins seems to have worked. Not sure why channel 1 is not working.

Thanks for your help

Hi Ben

Thanks for the reply

I will try using channel 2 and remap the pins.

I dont think the SPI component starts the reset, I think it just prevents some of the other features working (like the flash on the pin)

Thanks
