Hi rtrbt,
yes indeed. I totally forgot the PINOUT is different compared to older models.
Works fine now with these mapping. I can see my bricklets.
Thanks for your help ! Maybe you put a section in the Doc. I will not be the only one I suppose that runs a Raspberry Pi5 with a HAT and it is supported by Tinkerforge.
Regards,

Hi rtrbt,
I have update firmware and daemon to this version. It connects but does not show me any bricklets. Same behaviour I had on my Pi4, so I added to the /etc/brickd.conf these mapping
bricklet.group0.spidev = /dev/spidev0.0 bricklet.group0.cs0.driver = gpio bricklet.group0.cs0.name = gpio23 bricklet.group0.cs0.num = 23 bricklet.group0.cs1.driver = gpio bricklet.group0.cs1.name = gpio22 bricklet.group0.cs1.num = 22 bricklet.group0.cs2.driver = gpio bricklet.group0.cs2.name = gpio25 bricklet.group0.cs2.num = 25 bricklet.group0.cs3.driver = gpio bricklet.group0.cs3.name = gpio26 bricklet.group0.cs3.num = 26 bricklet.group0.cs4.driver = gpio bricklet.group0.cs4.name = gpio27 bricklet.group0.cs4.num = 27 bricklet.group0.cs5.driver = gpio bricklet.group0.cs5.name = gpio24 bricklet.group0.cs5.num = 24 bricklet.group0.cs6.driver = gpio bricklet.group0.cs6.name = gpio7 bricklet.group0.cs6.num = 7 bricklet.group0.cs7.driver = gpio bricklet.group0.cs7.name = gpio6 bricklet.group0.cs7.num = 6 bricklet.group0.cs8.driver = gpio bricklet.group0.cs8.name = gpio5 bricklet.group0.cs8.num = 5
After a reboot I get this in the /var/log/brickd.log and deamon is shutting down.

Does anyone tried to put the Hat on a Raspberry Pi working ?
I get this error in the /var/log/brickd.log

Hello guys,
I am trying out the standard java example of ExampleScanForTags. It scans a lot every second. Actually I just need when the ID changes and not if not. Is there some code that does that ?
Same way as the brick viewer shows it. Only when it changes.

Yes...thank you very much.

This link is dead. https://download.tinkerforge.com/3d/TBD/TBD.step
Does someone download this before and is willing to share ?

Hi Seismic,
thanks for the info. Good to know.

Hi there,
Is there any documentation how to connect those two ? On the Silent stepper I got 4 cables and on the servo 3 cables. Which goes where from to where ?
Any help appreciated.

Hi,
I am trying to set the min/max memory my java program can use on the red brick.
There is not a lot of information provided how to set it.
I specified JVM Options: -Xms 64M -Xmx128M
Invalid initial heap size: -Xms 64M -Xmx128M
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
What should be the right syntax for this ?
Thanks,

Moin,
ich habe nur einen Master Brick und 4 Sachen verbunden. Das musste doch eigelich gehen. Wieviel braucht einen normalen Java program um die Sensoren met 1Hz aus zu lesen ?
Mein setup ist :
-
Master brick 2.1
- Segment Display 4 x 7 Bricklet
- Motion Detector Bricklet
- Ambient Light Bricklet 2.0
- Temperature Bricklet
MfG,
Rik -
Master brick 2.1

Ist auch mehr fuer den Staff hier ob dss normal ist 😀
TinkerTeam ist das einen bekanntes Problem oder neu ?

Ich habe 1.15 auf den Red Brick und ich habe das gleiche. Wenn ich dann auch das Java program laufen lasse dan ist CPU 100% und wird fast nicht mehr idle.
Ist ueber 30% Last fuer den brickd normal ?
Und die CPU freq ist maximal
Every 1.0s: cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq red-brick: Thu Mar 26 16:58:26 2020

Gibt es schon einen neuen Releasedatum. 3-4 Wochen sind schon lange vorbei.
Need some help with Callback listeners in general
in General Discussion
Geschrieben
Hi,
I don't see any examples how to extend callback listeners or create new ones. Just an example with no meaning in Java from the documentation.
For the servo there a 2 OOTB examples, but I want to create my own for
getCurrentPosition or current used on the servo as example. How do I implement this properly ?
Regards,
Rik
