Re: thoughts on prices and features for addons

Have the SenseHATs too, can't complain other than no light sensor. But then it was designed for astropi and the camera can be the light sensor The ability now to emulate it for a large class to use is excellent and then move it to the Pi. If they had remote I2C (say if gpiozero evolved) and it was a...

Re: while loop question

I've used gpiozero module for a clock timers. You can also use a button group if I remember correctly. It's there to make buttons a bit easier for beginners and other alike. But it can be a bit slower with to default gpio setup. But it's an easy change. Another thing to look at, touched on above. Is...

Re: Simple Temp monitor Question

The one with less it's is the best. (On the right)
Less to go wrong and less connections

Or buy a PiW it's cheaper and solder wires directly to the gpio holes to some strip board and solder the wires and ds18 to that.

Re: Most accurate gps chipset

It's not just that, it's just a restriction in the system used. Only recently has a higher accuracy channel been available from the satellite Even a GPS/GLONASS combination is only down to 2 meters iirc. Though it does give more Satellites to get a lock on (hence less drop out) You'll need an additi...

Re: Raspberry Pi - Arduino baud rate missmatch when using mini UART

It says how to do it in the link above to the docs I gave.
It a line or two in the config.sys and then just use ttyAMA0 (or serial0).
In fact if you always use serial0 it will/should always point to the UART pins

Re: Configure RPI 3B as both AP and station?

As far as I know you cannot have it 'at the same time'. But have one of mine setup as you may be wanting and in the rc.local it runs a little programming that if it first detect a now SSID it will try to connect to it. If it fails or if there is not one in the list it will then trigger into AP mode....

Re: GPIO UART incorrect baud rate

Have you tried it with the full fat UART. I.e. turn off and disable Bluetooth. Oh and you just shouldn't need any of the other faff, turning the UART on set the 250 and stuff needed in the background. The rest just slows the Pi itself down if I've read it right. But I do not know Arduino so cannot s...

Re: GPIO UART incorrect baud rate

Unfortunately I cannot help you.

But I can link you to the techy details they have on their website, if you not been there already.
https://www.raspberrypi.org/documentati ... on/uart.md

Perhaps a way to see if it's a mini-UART problem is to temporarily switch to the full fat UART.

Re: More frequent updates?

One alternative
Once you make your image and update it, copy it to another SD card.
Then when it comes to making images just update it and copy it.

There has been a new leap in tech on this, I think Broadcom (47755 iirc) are making some with accuracy down to less than a meter (30cm/1' )now and probably others may be using it as well. Look for L5 use. Normally you are looking at about 5m accuracy, less if you sit there for a while and could get ...
