Hi there, 

 

Currently i integrate the ft232r usb uart ic chip with labview platform.

 

I am conducting a basic test to check if the chip can communicate well with labview.

 

The chip is set to send a feedback signal once it successfully recieve the command. eg. I sent "ST0201;" to the chip then get a feedback signal "535430323031"

 

I test it succefully on a third party serial communication software (attached the capture pic below), but it seems doent' work on labview.

 

But when it is connected with labview " continuous write and read.vi", my command seems cannot sent succeffully to the icchip.but the signals in the  first row "nRF24L01 USB Dongle" means labview can recieve initial data from chip. So i can conclud that my chip actullay connect ok with labview

 

I check for a long time then found that my chip is only supportable for byte command.

 

Is it the problem that the command type sent from labview is string so that my chip cannot recognize that ?

 

Or is it any other problem?

 

Thanks

 

Regards,

Newbie from singapore
