Re: Pi as a modem/router

I don't have anything running on the amiga core at the moment, I have looked online and people have been using terminal software such as Aterm of Ncomm on the amiga to connect to the pi then om to the internet.

There are videos on youtube but no descriptions of how it was done.

Pi as a modem/router

Not sure if this is the right place. I have a Mist FPGA on which I run an Amiga core, this has no network interface but there are pins that expose a serial port, I know I can connect the serial port on the mist to the serial pins on the GPIO on a Pi Zero. What I want to know is what software do I ne...

Re: GPIO Power

Both ways work, I just wondered if there was a right or wrong way.

If I can find them under my pile of cables I am going to use a short usb cable as this will leave the gpio free.

GPIO Power

If I use the gpio header option for power do I plug the usb from the powerblock into the pi or the display board?

Re: Unable to address I2C on MCP23017 IO Expander

I can't make out from the photo but have you connected the pins on the MCP23017 to select the address? Pins 15,16 & 17 need to be grounded or to 3v3 to select the address.

Collactable

I have a mint in bag Maplin GPIO breakout board for a Model A/B raspberry pi, should I keep it so that in few years my kids can have it valued for thousands on Antiques Roadshow or cannibalize it for my new model B+?

Re: Pi-mote from Energenie

The controller cost me about 10 UKP in materials, (ATMega168, resonator, 433MHz transmitter, connector) and uses I2C for the communication with the Pi. I made it stackable, so it doesn't obscure other GPIO use, and used a simple lighttpd setup and a simple C application (CGI) to allow it to be run ...

Re: Stepper motor keeps buzzing instead of turning

Just got another board and motor today. The values of WaitTime that worked were 0.4 to 0.004. I tried the original board and motor again and the same values worked. I am waiting for the third unit to come and then will report back with detailed analysis of the WaitTimes and other changes needed.

I have just got the same board and stepper motor, I had the same problem and thought the motor was broken. I found that changing WaitTime to a smaller number worked I first tried 0.005 this worked, various numbers between 0.09 and 0.001 worked but not the 0.5 or 0.2 in the examples. I have ordered t...
