Re: BV4627 Change I2C address on RPi - 7 years ago

Just to let you know i managed to do this in the end, took a lot of playing around but here is the short version: sudo i2cdetect -y 1 -- gives current i2c address default is 32 python from notsmb import notSMB bus = notSMB(1) bus.detect() -- this will give current id (50 by default) bus.i2c(50,[82,66],0) --(82 is to set new address, 66 is new value) bus.i2c(50,[85],0) --(r

BV4627 Change I2C address on RPi - 7 years ago

Is there a way to change the address via I2C? can i do it via notsmb? if so are you able to provide me with the steps? I've been trying to setup the board via serial on the raspberry pi but as the models i have are not usb, I'm struggling to get something working over binary.

ByPic Tutorial & Rookie - 10 years ago

I would find a complete tutorial PDF file, better suited to my style of effort than the current piecemeal setup. Also, I am under the impression that the interpreter program, "rookie" is not resident in the PIC MPU, as shipped, but is to be downloaded from the Web site.

Re: BV4111 and Raspberry Pi - 11 years ago

I've tried it with two different versions of raspbian, and they send me the same error. If it's still not working, is it possible to send back only the bv4111. The relay board works properly I'm an Italian customer, what's the easier and the cheaper way to send it back in the UK?

Loading - 11 years ago

I'm trying to load project_1.bas as shown in your tutorial. I have downloaded BV_COM2 and have called up the text file transfer box. I've then copied the URL into the top window, put cold……. in the bottom window and ticked send first. If I now click on the send button, I get an error message that COM3 is not open. Why do I need COM3 if I'm downloading from the internet?

I've got the board up and running fine and entered some real-time code and got everything working. However, I am having constant difficulty uploading code to the unit from the web site. The documentation says you may have to try it a few times, but after an hour of time-outs I'm now looking for an alternative method of loading the code. I've tried creating a basic file in PSPad and uploadin

Hi there, thanks for the swift delivery. I have assembled the micro controller circuit and have tried to load the basic program project1.bas however, the text loader fails to load the program.

I typed the program up externally without the comments and I got the same error and it then said there is a problem w

BV4618 - 11 years ago

When connecting to the keypad, the rows and cols were reversed. When I assumed that the C0-C3 and R0-R3 on the interface were reversed then it worked fine. The keypad itself appears to be correct using a meter. I cannot get the interrupt line to work on the keypad connector. I get an active low with the first key but it never resets. Which command is used to get the key char when using interru

Also port 7 is also not giving a PWM. So now i am linited to only 3 PWMS.Please check out on this. Attaching the PWM

BV4113 Motor Controller - 11 years ago

Hi, Due to the number of outputs, my project requires 3 BV4113 boards which I've configured with addresses 'a' 'b' and 'c'. However, I also require a couple of input lines and my understanding from the documentation is that I can only receive feedback from multiple devices in non-inverted mode and so as I'm controlling via a standard PC COM port, that is not possible? On that basis, I'm initia

Speed - 11 years ago

I am considering using the BV513 board and pic32 basic to measure flow from a paddle wheel sensor. The sensor pulse rate varies from 0 - 300 Hz. I wonder of the interrupt function would be fast enough to handle this task.

BV4626 Input - 11 years ago

We've got it working and can talk to it using the VB demo etc, all good. However I can't for the life of me work out from the manual how to use it for what we want. Essentially we want to monitor a circuit to see if it is open or closed and tell the computer whether it is or not. I'm sure I asked this before I bought it but it was a long time ago. Can you confirm if this can do it, if s
