Re: Problem with UART

I know this works as I have just tested it with my MAX232 Circuit. The problem may lie with your max232 circuit. import datetime import os import time import serial ser = serial.Serial('/dev/ttyAMA0', 115200, timeout=1) date = datetime.datetime.now().strftime( "%d/%m/%Y %H:%M.%s" ) ser.close() ser.o...

Re: Raspberry keeps sending serial data at boot

I already have the max232 level converter setup on the pi. and I have just checked this for you the first thing that is transmitted out of the onboard serial port (ttyAMA0) at boot is the word "Uncompressing". I have checked it 38400 also and from the PC side and left the R-Pi at 115K and you just g...

Re: Connect RPi to external MySQL

I had a similar problem and in the end it was the user privileges that were the problem.

Make sure you have the port open on your firewall to allow traffic over port 3306 (I think that is the default port)

The mySQL client works perfectly on the R-Pi using Python.

Re: USB RFID door alarm system help with code needed

Which Make/type of USB RFID reader is it ?, as it is USB it might appear as a Serial Port and use can use pyserial to listen to it.

Re: RF serial via USB port

There is a program which comes with pySerial called miniterm.py which is something akin to hyperterm, I have not used it myself so I don't know what is can do but it might be worth a look to setup up your RF devices. I assume you have setup PySerial on your R-Pi ,you will find it in the pyserial-2.6...

Re: RF serial via USB port

Roger, Have you tried using just a USB2Serial converter and connect it to hyperterm to ensure you are actually getting something out of the R-PI. I have been using the Pi with a Prolific USB2Serial Converter and it works perfectly using a small Python script. I think your problem could be how the mo...

Hello Tony thanks you for the detailed post. Have you actually tried this and does it work ?.

Would it be possible to get a 'Ball Park' price on the Pro Version per Unit and any pricing structure you might have for multiple units per customer. We are looking forward to seeing the full capabilities of the Pro Version in action.

Re: Broken SD card slot

The original design is a bit flimsy, I am going to only use the microSD card holder which make the SD card flush to the edge of the PCB. Maybe in the future they will use a stronger Card Holder with a full back on it to stop this happening.

Re: Broken SD card slot

Joan, that's a real pain in the rear end to do and it can break again, I am not saying my way is the best but it is more robust, that is why I did not bother gluing the pieces back on.

Re: Question about using the RPi with a relay.

Joan,

Its a 'No Brainer' then. so it supports 3.3v, so it can be attached directly to the R-Pi.

It actually looks like a nice little relay board and for $10.00 plus shipping good value too.
