Yea it was the carriage return, cheers!

Hi, I want to use DAQfac to repeatedly poll a device for info using the same command, and store this data. This command works fine using putty or teraterm etc, (you get the results and no echo) but when I open a serial monitor window in DAQfac with the same baud settings etc. and try it, I just get an echo of the command and nothing else - do you know what I might be doing wrong? Just to help, let's assume I'm a dumbass who has no idea what they're doing ok, cheers

Hi, I'm using DAQfac express, and trying to send an email following the user guide , but getting the error below on the first line: private semail = new(CEmail) Class does not exist, can't instantiate.: Line 1 Can express not do emails, or am I doing something wrong? Cheers

Brilliant, thanks, works great making control so much better than the trinamic IDE that came with the driver. The final code below for others if helpful: function Cmd(address, instruction, type, motor, valuein) private tosend tosend[0] = address tosend[1] = instruction tosend[2] = type tosend[3] = motor tosend[4] = transpose(from.urbLong(to.uLong(from.urwLong(valuein))),0) private cks = sum(tosend) & 0xff return(chra(concat(tosend, cks)))

Hi again, the following line works perfectly: device.QBCrig.Poll(ChrA({1, 1, 0, 0, 0, 0, 0, 100, 102})) Even though the output, as you said, is just control characters: ? ChrA({1, 1, 0, 0, 0, 0, 0, 100, 102}) But using the function as you suggested (I changed 'out' to 'tosend' as I thought that might be conflicting somehow with the 'out' in the poll function but it isnt...): function Cmdcopy(address, instruction, type, motor, valuein) private tosend tosend[0] = address tosend[1] = instruction tosend[2] = type tosend[3] = motor tosend[4] = from.urbLong(to.uLong(from.urwLong(valuein))) private cks = sum(tosend) & 0xff return(chra(concat(tosend, cks))) I get this: device.QBCrig.Poll(Cmdcopy(1, 1, 0, 0, 100)) C1136 Timeout: Cmdcopy Line 20: Cmdcopy Line 28: Line 1 and the actual output its trying to send is this: ? concat(tosend, cks) {{1, 0, 0, 0}, {1, 0, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 100}, {2, 0, 0, 100}} ...which isnt correct, as there should always be 9 bytes sent and received. I'm confused as C1136 isnt in the user guide, and there are only 9 lines in the function above, so I assume lines 20 (Write(out)) and 28 (throw())refer to the poll function (basically the same as the given one), and there's a problem with the format from the function above. A little more help please?

Wow thanks so much! I love your program by the way, and the support you give is amazing too - if theres any way to support you then let me know, thanks

Hi, I'm trying to make a sequence function to formulate commands to be sent to a TMC stepper motor driver. Each command is in binary in 9 bytes, with some info about addresses, motors etc in each of first 4 bytes, then the value in the next 4 bytes (MSB), then the last being a checksum of the first 8 bytes. A typical command which works is this: device.TMC.Poll(ChrA({1, 2, 0, 0, 0, 0, 0, 100, 103})) My function based on the topic above is this: function Cmd(address, instruction, type, motor, valuein) private string out = format("%03d", address) + format("%03d", instruction) + format("%03d", type) + format("%03d", motor) + from.urbLong(to.uLong(from.urwLong(valuein))) private cks = sum(asca(out)) & 0xff return(out + cks) But isnt quite working - the Long conversion isnt concatenating with the rest of the string properly - could you tell me what I'm doing wrong please? Many thanks!

Actually found this topic where youve explained it already - many thanks

Hi guys, Sorry for how basic this question probably is, but I've read the serial comms guide, but still can't work out exactly how to send 3 bytes of 1 0 1 in the monitor window - with a <CR> as the end? Do I just write 01 00 01\013 and click send? Do they need spaces between them like that? As this doesn't seem to work and it should I think? Many thanks
