Re: Protocol j1587
Hi Well done on getting it working. Following on from Martin above, your engine is constantly sending out a data dump containing many values that are of no interest to you and you will be processing these too, hopefully rejecting, but you will still be processing everything that is coming in. I don'...

Re: Error when returning a string from a macro
Hi I would need to see your chart to be sure but it looks like you are trying to do a type conversion within a calculation. Unless both variables are of the same type you cannot just use the equals (=) to assign values. In your screenshot, it looks like you are trying to assign the value of local va...

Re: ESP32: (unidirectional) RS422 component?
Hi
Could you just simply set "Use Tx" to "No" thereby freeing up the pin?
Regards

Re: History of Flowcode
Hi Thought I'd update with the latest edition to my arsenal. Pictured below is a SysBlocks board. This pretty much is a "lab on a board" for experimenting with DSP. It came with two SMA to SMA leads, two SMA to BNC adapters, a BNC T-Piece and a 3.5mm to 3.5mm stereo jack lead (auxiliary lead). Power...

Re: ESP32 and WS2811: init in macro not working
Hi
Does it fail to compile if in the Macro or does it just not work (initialise)?
Using a PIC it compiles in either.
Regards

DSP made easy
Hi I should perhaps have entitled this post "DSP made easier" as unless you have a brain the size of a planet and perhaps hold a doctorate in mathematics too, DSP is never going to be easy for mere mortals like myself. Digital Signal Processing is everywhere you look (and listen) and decades have pa...

Re: Decimal conversion to Hex value to load a PLL
Hi I haven't used that chip so I may be completely wrong. Page 17 of the datasheet explains the 16-bit number structure and as far as I can see for convenience and ease of reading it is "broken" into 4 x 4-bit Hex values for convenience. 16-bits = 1111111111111111 in binary, FFFF in Hex and 65535 in...

Re: Adafruit DRV8871 Motor control module
Hi The module can either run a motor forwards or backwards (at full speed) depending on logic levels on Pin 1 / Pin 2 as you describe above. To adjust the speed you need to use PWM on a pin. Using forward direction (and your pins) as an example, You would set Pin 1 Low then enable PWM on Pin 2. Puls...

Re: Protocol j1587
Hi Just reading through the posts and catching up. I assume you are referencing the above file. So if I've caught up correctly, you now have the chip connected to the bus and you have 221 displayed, meaning the programme has successfully interrupted. If so that's good. In the file, you branch to the...
