Hi Kwinn,Thanks for the reply,I am assuming that the FT232 Chip is handling the timing (re different baud rates), as it's internal buffer of which detects the bits being sent and received.I have tested again, and definitely that DISABLING the Driver on the transmit side causes this problem.I can't get my probes ( of my scope) into the USB/485 Converter as it has a hard moulded case. I would like to see what the bits are doing there in relation to the driver enabling line.I have sent off another message to FTDI Support, and i guess I will have to wait for their reply.thanksDave M. Thanks Guys!I haven't finished yet!,I still have to transmit from the MAC to the PROP and NOT USE RTS lines, This is why I used the FTDI chip in the first place it supposed to handle this for you. I have had lots of issues with software control on the MAC/Realbasic side of things,mainly not knowing the status of the buffers.I have a modified FD Serial Object to handle RS485 timing, this is working really well.
Realbasic Serial Communication Test
I still need to work out error detection etc.I am also working on a small serial tool in realbasic, that helps with RS485 development, I might post it here as it can be used on MAC/PC & Linux and you can use the source code.If I could find how to make screen grabs form my oscilloscope RIGOL DS1052E, then I could post these here to explain the issue even better.regardsDave M.
Python is a general purpose language with tremendous community support and a 'batteries-included' philosophy that leads to simple-designs that focus on the business problem at hand. It is a good choice for a wide variety of projects.The only reasons not to choose Python would be:. You (or your team) have greater experience in another general purpose language with good library and community support. You have a particular problem that is handled best by a specialty language that was written with that sort of problem in mind.The only thing I know about RealBASIC is that I hadn't heard of it until now, so it's a lock that it doesn't have quite the community of Python. (Exhibit A: 60,000 Python questions on SO, only 49 RealBASIC questions.) And if it is a derivative of BASIC, it would be not be a specialty language.Python seems a clear choice here, unless it means learning a new language, and you are proficient with RealBASIC.
