Re: RC5 Remote Controlled Clock

Thanks Ben

Those boards are very useful, I use the 1/4 size a lot as well, although they are a bit expensive compared to veroboard they are very high quality.

I've just tried a simple flowchart for the DS1307 under V7.3 and it seems to work here.

Hi Slobodan

You will have to wait till Matrix open again on Monday, they will soon sort out you problem.
PM your problem and details to David

Re: Building Components - Step by Step Guide

Hi Dave
That's a great document.

Like Steve I've tried component creation and not had much success either.

I have those RF components myself, and have used them by programming them "the hard way", now I'll try working through your tutorial and see what happens.

Thanks again.

Hi Chris Sorry only just spotted your post. If I remember I have a small (different) transmit delay in each of the sensors to stop data transmit clashes.

Hi Ben

The Adafruit board has a default Ic2 Address of 0x77, (0r 0x76 if SDO is connected to GND)

Can these address be added to the component please, as It currently on allows 0xEE or 0xEC

Re: BME280 I2C/SPI Temperature Humidity & Pressure Sensor

The board is on its way, so should be here Fri or Sat. I've knocked up a quick FC program to read the 3 values in a loop and display them on the EB005 LCD Board

Will post my findings once tested.
