I tried running prolific usb - serial comm port but there is no communication.ĭo i need to change the program in c# application. Is the device class same for both : usb serial port (mcp2200 ) and (prolific usb-serial comm port). That is why i want to use prolific usb-serial comm port. But the mcp2200 gets disconnected very often and there is error that usb device not recognised. The c# application wass made using mcp2200 module in mind. Please find the attached images for reference. Mcu tx-rx ->max232->db9 female connector -> dm9 m connector on module pcb->max232 on module pcb ->mcp2200 on module pcb-> usb connector on module pcb ->cable usb-> usb port on laptop. So i am connecting the system as follows : Since you read the buffer it clears it, then you get another event and get the ady and again you ignore.
I have build an c# application which connects to an embedded mcu based hardware via uart communication. The Serial.DataAvailable may fire when Re is received, you go to do a 'Serial.ReadAll and don’t recognize it or ignore it.
