Re: Serial port communication

Hi

I've had bother in the past with USB/Serial when trying to implement flow control.

This is quite interesting

Re: Serial port communication

Hi My understanding is that Xon / Xoff are ascii and can't be present in data. I don't have the greatest Arduino knowledge but from forums it seems it's going to be tricky for you https://forum.arduino.cc/index.php?topic=15676.0 as neither H/W or S/W control is supported. I stress my knowledge on th...

Re: Serial port communication

Hi

Not sure I can be of much help but I too have had issues implementing software control in the past. Does your circuit allow for hardware control for comparison?

Re: EB006V9 PIC Programmer

Hi

I might have one without Ghost, need to check.

My board(s) are 9-pin too but Matrix sell adapters (BL0113 and BL0119) so your old board(s) can be compatible with a new programmer (and vice-versa). That may be a better option.

Re: Opening a Version 4 program in Version 9?

Hi I think you will have issues trying to do a straight conversion from v4 to v9. I think you may need to go "via" v7. Programs I have in v5 can be opened in v7 but not v9 and if I open v5 in v7 and save, I can then open the new v7 in v8/v9. I don't know what, if anything, is lost during this though...

Re: Serial receive using PIC18F4620 not working

Hi For a baud rate of 9600, that would equate to a character being sent in approx 1mS so I would assume that v5 trace would be working. I haven't got one of those chips myself to check but I would look at configs. I know it is simplistic but an led flasher as suggested elsewhere is a good sanity che...

Re: DQ542MA Stepper Driver

Hi Further to Peter's answer above, I too can confirm an output train of pulses using his code. You mentioned earlier that your motor isn't doing anything so things to check if you haven't already, and sorry if this is stating the obvious. It isn't clear your control connections. The controller has ...

Re: Binary representation in watch window

Hi

I definitely agree there are good improvements in each version, although some can take a bit of "adjusting" to <s>. I started with V3 and I've still got an old combo-board with the BT-plug connections kicking around. Museum piece perhaps? <s>

Re: Binary representation in watch window

Hi I too think it would be a nice selectable feature to change the format. Meanwhile there are many calculators out there for both on and offline conversion. My favourite is Dec Hex Bin ASCII Converter (by Colly Dog Code), available from the Google Play store. As you enter a value in any of the form...

Re: External circuit

Hi There are simulators available that will allow you to model your RC circuit and also run the hex generated in a modeled microcontroller. Indeed TINA (www.tina.com) openly advertises compatibility with Flowcode and is also available from Matrix themselves. You specify your microcontroller (AVR sup...
