Hey all. I just bought the 4wd here and I cannot seem to connect my PC with my BAP 28 in my Bot Board II. I’m using the USB-> serial cable (FTDI USB-to-serial adapter cable FT232R chip) that is sold with the robot on the Lynxmotion web site. I have installed the drivers and run the software.
I can get the Basic Micro Studio program to recognize the correct COM port when I plug it in. It seems to know which COM port I have used so something is connecting. I have tried changing from COM1 , COM2, 3, 4, 5, 6, 7, 8, 9 and 10 and the software always knows which one I’m using, but cannot connect to the BAP 28.
When I choose Tools-Preferences- Find Processor it always says “Could not find processor”
I have tried changing Advanced - Reset Hold time from 25 26 27 … all the way to 100 with no success. Also tried 25 24 … to 0. No help.
I have a question as well. When I connect the 9v battery the 3 LEDs ABC cycle in a pulse and the speaker gives a chirp. As far as I know this is a default program on the BAP 28. Do I need the 9v battery connected while I try to connect to PC??? I have tried both ways and does not seem to make a difference.
Also I have tried this on my Windows 7, 64 bit desktop PC and repeated the whole process on my Windows 7, 32 bit laptop (Using the 32 bit drivers) The same problem with both.
I just can’t get Basic Micro Studio to find the BAP 28.
Any ideas??? I am so stuck and just can’t think of anything?
The BotBoard II must be powered in order to function whenever connected to the computer. The DB9 serial port does not provide power.
When having troubles with a USB-to-Serial converter or adapter, please follow these steps:
]Make sure the appropriate drivers are loaded and that the module is recognized by the Operating System. In windows it will show-up as a COM port and in Linux as a device /dev/ttyUSB0 for instance.
The most common drivers can be found here: ftdichip.com/FTDrivers.htm
/:m] ]Once the module is properly installed, do a Loop-back test. This test consists in connecting the RX line to the TX line and sending messages through a serial communication program such as Hyperterminal in Windows. The messages should immediately come back since the lines are connected together.
/:m] ] If there are still problems and there are no shorts or power supply issues, then it is likely the interface is defective and that you will need to exchange it. Please provide your invoice number and product code when requesting an exchange./:m]
I just did a loop test with my Serial-USB converter and found it worked just fine. Then did a loop test with the serial cable and it failed (both results were repeatable), so it looks like the serial cable I found in the storage basement was just plain broken. I’m gonna hunt for a new cable. I think that was my problem.
Lesson to be learned.
If you are not sure, DO a loop test.
