Hello all. Using an ECIO40P16, I made one observation today that originally caused quite some confusion... Exploring available ports I simply placed an output icon a macro, and with masking enabled (highlighting mask-able ports) I was able to quickly explore exposed ports used available to the code....

First, a huge 'Thank you' to afficianado Kersing, who kindly presented me with valuable direction on the subject of directly messaging Flowcode over USB from Linux, to negate the requirement of third=party USB-Parallel interface for high-speed transfer of data. Given the number of hits this topic ha...

Hello All. I'm currently working on a project to interface high-speed Flash read/write data between the PIC and Linux host via FTDI's FT232H device, and then to Flash memory. The FT232H essentially offers required Linux drivers and parallel SPI, which lends itself to this application well, as releva...

Hi Ben. Sincere apologies for the time to reply... Extremely busy times, long story... However, further information suggests that I'll need to be in a position to handle either binary data/header or hexadecimal text file formats, and FF's would create the more obvious issues over USB232. I've theref...

Hello good people. I'd be grateful if someone could give me a pointer on flow control with the USB-Serial component. I'm developing a project to serially load bytes to the PIC to program a large I2C EEPROM (256kB) in real-time, pogrammed in pages of 256 Bytes from a simple console. To avoid creating...

Hi. Without sight of your code, I can only flag a few pointers which may or may not be of help... Instead of manually stepping through the code, let it free run but slow stepping right down to perhaps 1s per step. Then, while running, click and hold the pushbutton throughout the complete simulation ...

Thanks for addressing this issue Ben. We do a great deal of simulations with deep processes, status indicators, display, debugger panel, etc, for development and debugging purposes. With our latest projects, simulation delays of even 1s invariably cause Flowcode to crash after a period of free-runni...

Hi Ben So you can either return the board to us and we will apply the fix or you can apply the fix yourself. I will make sure that the up coming batch of EB091 boards are corrected so USB will work straight away. There was also a minor Flowcode definition change to alter the USB prescaler and allow ...

Thank you Ben,
Entirely appreciated

All the best,

Brendan

I'm liking this new EB091 board and choice of embedded dsPIC. When selected as the target it all appears to be working so far - with the exception of the USB port of the target chip. Currently, when I initialise the USB through the USB Serial macro, not a blip in Windows Device Manager in response t...

Excellent news.

Thank you for the confirmation, and I've no doubt your discoveries will be of future assistance

All the best,
Brendan

Hi Rob. Please rest assured that if a string of bytes is compiled in the way I suggested, no Carriage Returns will ever be present in the original string, or transmission if sent from the RS232 component macro as a string. What you observed will have been externally generated following the transmiss...

Hi Rob. I do lots of stuff over RS232, though I'm not sure I understand your question. To clarify, I trust you're declaring hexadecimal appropriately (0x..) ? Fundamentally, the question is largely how you intend to process or view the data at the receiving end. For example, if I were using a progra...

Further to Ben's advice, I can add that I've been caught out before by trying to do 'too much' on one line when concatenating strings, or combining strings with functions, for example... String2 = String1 + " = " + ToString(Integer_A) + ToString(Integer_B) I've had very quirky results, even with ple...

Hello Again. First, your data is looking considerably better now that you've slowed things down :) I've taken a quick look at your code and my first advice is to get rid of the decision operator and connection points in order to exit your loops. Connection points , while 'OK' in many instances, are ...

So in total i have to send 2 bytes for the first wordb, 2 more bytes for the worb again and then 2 more bytes for wordA, this should initialize the chip. Yes, I believe that should do it, though haven't studied the datasheet in any depth as I'm presently working on an urgent consumer project. Then ...

I understand and empathise... If you can follow my first example, I'm sure things will quickly click into place :) Think of a string of 1's and 0's just typed on an old-style typewriter, where the amount you temporarily move the carriage to the right is decided by the value in LoopCount, and the bit...

Hello again. Once you've established your register values then you need to extract the individual bits and send them serially. For example, if I had a value in 'SendByte' that I wanted to send in this fashion (MS bit first), this is one of a number of ways you could do it... 1. Create a loop that co...

Hi there. I'm sorry I've no time currently to help in any detail, but a quick glance at the datasheet confirms this chip doesn't actually employ I2C at-all. All you're doing is clocking single bits into a 16-bit wide shift register (repeated to successively program Latch-A and Latch-B), so you shoul...

Hello FC team. I have suggested this elsewhere, though relevant to this thread in particular... Due to our successes using Flowcode to develop bespoke, portable, standalone test rigs, we're now integrating large capacitive touchscreens and FTDI's "Vinculum-II" chipsets into the mix. This will suppor...

That's fantastic - Thanks Ben

All the best,

Brendan

Hi.

Thanks, and continuation lines noted.

I was attempting to use the same double-click method as per calculation and other flow icons, but have observed that drag-&-drop must be used for the C component.


All the best,
Brendan

Hope you all had a good Xmas :) My 2-bits... When editing the 'C' component macro, I believe it would make perfect sense for Flowcode to facilitate selection of declared variables/C-styled functions/etc (just as with any other component macro or calculation), plus automating uppercase conversion and...

1-wire timings are critical and must be strictly adhered to. If you're trying to use the internal RC oscillator (8 MHz) then you could try playing with the OSCTUNE register as timing tolerance may play a part. Whether or not others have successully had it working on a specific PIC is only part of th...

I'd used Norton Internet Security for years, though dropped it after it couldn't remove a morphing virus that waltzed in, so I located and removed it manually. I then installed Kasperky which promptly discovered five further viruses on the system and automatically removed them. Time and technology m...
