Hello, Color-Sensor : The 16-Bit Values "Red", "Green" Blue" might be : fraction of RGBI (4x 16-Bit Raw-Values Mode 5) or HSV (3x 16-Bit Raw-Values Mode 6), but your observed Values are strange for HSV Also strange that according to Sensor Init-Data all 3 HSV RAW Values should be in Range 0 to 360° but Saturation and Intensity are according the HSV-Model in Ranhe 0 to 100% To can clarify what exacly is mapped, there has to be evaluated the Write-Command (0x54 with 4 Data or 0x5C with 8 Data) from Hub to Sensor that issues Mode-Combining Force-Sensor : The 16-Bit "ForceA" could be : ForceRaw (1x 16-Bit Raw Value Mode 4) or ForcePeakRaw (1x 16-Bit Raw Value Mode 5) Again here, to clarify what is really mapped, can only be clarified when evaluating the Write-Command (0x54 or 0x5C). Your FPGA is able to also read Data on TXD-Line (Pin 5) from Hub to Sensor. Can you do a record of this TXD-Data starting after switch over to 115200Bd or trigger on 0x54 or 0x5C on TXD Line to evaluate the Combine-Mode Data Jo

Hello, At Bricklink there is listed Tile 3068bpb1883. when you zoom the Picture, you will notice that there is no Green-Red Start Pattern. Seems to happen also at 3068bpb1910, 3068bpb1914, 3068bpb1918 & 3068bpb1911 Has anybody more informations about this ? Jo

Hello, Does you have records of the TXD-Line (Hub to Sensor) just before observed Values are starting (after initiialisation) ? I think you will get Mode-Combined Data (Mode 6 + 1 + 0) -> 3x Word with HSV Color-Data followed by 1-Byte Ambient-Light (max 100% -> 0x64) and finaly the Color-Index (max 10 -> 0x0A) that would explain the strange max limit of 2660 (0xA64 -> 0x64 0x0A with least significant Byte first) I would expect a Mode-Combining-Command similar to : 0x54 0x23 0x00 0x60 0x10 0x07 or 0x5C 0x23 0x00 0x60 0x10 0x00 0x00 0x00 0x00 0x0F Jo

Hello, More Info on the UART Protocol you can find here : https://github.com/pybricks/technical-info/blob/master/uart-protocol.md and also here Frame 52 00 C2 01 00 6E is the Comand "Speed" with the 32-Bit Valie for the UART Speed of 115200Bd. 6E is the XOR Checksum. Jo

Hello, Philo did Reverse-Engineering of the UART Protocol. You can find his results on his Page : https://www.philohome.com/wedo2reverse/protocol.htm There are also Logic-Analyser Records of some Motors and Sensors at Initialisation Phase and "normal" Data-Transmissions Jo

Sounds promissing. Is there a description how to get Code and Firmware into Inventor/Spike by USB ? I did not find. On Github I found Firmware-Files only for Control+, City- & Move- Hubs only. Where can I find Firmware for Inventor/Spike ? Is Firmware for Spike-Essential the same as for Spike-Prime ? Jo

Is there planned to support also Prime-Essential ?

Can you go more into detail, how DCCready will look like ? How can we imagine a PFx Brick as DCC Decoder ? On your Page Brick Dimensions from 2015 there was in interesting DCC concept, but the electronic seems to be much different to the PFx Brick There was also mentioned to charge a Battery to can drive on non metal rails sections too. An Architecrue-Overview (wiring) of the options/possibilities (examples) would be nice. Jo

Only small remark : PU can have 0/2/4/6 (0=Mario; 5=Control+; 6=Inventor) external Outputs that can also be used as Inputs Beside external Outputs/Inputs there are also availavle internal Outputs (LED, 5x5 LED Matrix, Spealer) / Inputs (Gyro, Voltage/Current Measurement); ...) At BuWizz there are BuWizz 2.0 with 4x PF Ports and BuWizz 3.0 with 4x PU + 2x PF Colored connectors are only at BuWizz 2.0 PU Connectors Jo

@Zerobricks can you confirm : BuWizz2 : 1S2P 3,7V 2x 950mAh (7,03Wh / 3,7V / 2 cells) Driver 4x DRV8833 = 4x 1A BuWizz3 : 3s1P 11,1V 3x 800mAh (8,88Wh / 3,7V / 3 cells) Driver 4x ? = 4x 2A + 2x 4A and how is handled balancing at charging / discharging ? For charging you still need an Step-Up Converter/Charger, right ? Can you give here some hints ? Output-Current has increased from 1A to 2A / 4A What Driver are you using for the 2A/4A ? Jo

Hello, In this (german) Video at Timestamp 17:55 there is told, that there are 2 additional Power-Function Connector Pins used. Jo

Hello Does you mean by "full documentation" what is there : https://buildhat.readthedocs.io/en/latest/ ? If not, please tell us the Link, because about the serial communication I could not find at the "readthedocs" Page In the PDF https://datasheets.raspberrypi.com/build-hat/build-hat-serial-protocol.pdf the UART Communication is described very limited. On Github is a much better documentation https://github.com/pybricks/technical-info/blob/master/uart-protocol.md But unfortunately Documentation of the Modes of the Sensor(s), Motor(s) and LED-Matrix and the used Data-Frames are only very fragmented to find. In the PDF there is an example of the List Command that reports : speed PID: 00000BB8 00000064 00002328 00000438 position PID: 00002EE0 000003E8 00013880 00000000 Is this part of the RPI/HAT or from the PU-Motor (Type 0x30) ? On 2nd would be nice to find out, how this was transmitted on rhe UART from Motor to Hat/Hub What would happen with the HAT when using 9V (6x 1,5V AA Cells) ? Would that Toast the HAT, or would the H-Bridge-Driver support this ? Jo

Hello, Impressive pictures. Many thanks for sharing them I assune, that there are used the same chips (uC : STM8S103F3 marking "S103" and unknown 3D-Hall) like in other PU-Motors. Can you confirm ? Jo

When digging in Link kbalage posted, I found nice Info. It seems that Lego has patented also remote controllers in XBOX/PS4 shape and WEE-Format : https://patents.google.com/patent/US20200298106A1/en?q=lego&assignee=Lego+A%2fS&page=1 Why did they not introduce them with BLE and LWP3.0.0 Protocol for use with 42109 and other Jo

Hello, At Time-Stamp 2:24 you can see the correct alignment of the PCB-Assembly to Cable- & Motor- Connections The pictures from Time-Stamp 12:10 to 12:57 has the assembled PCB put 180° rotated on the Motor @zumaidi Is the PCB on the other side "empty" ? I think, that on the PCB-Part cliped on the white Housing with the red Cross-Axle Bush there will be placed the HALL-Sensor Does you conform ? Jo

Hello, Any Idea how new angular S-Motor can be made so small ? Looks, that there is no place for Motor and planetary Gear itself in "old" Design like M- & L- angular Motors. Jo

Hello, What in the LIB has to be updated to work also on a Arduino Nano 33 BLE (using a nRF52840 ) ? Is there planned an update to support also : Spike Essential Brick to Brick Comminication (by BLE Advertising Broadcast) Luigi Brick Motors & Sensors from Spike & Inventor Sets Jo

Hello, You can find here : https://social.sbrick.com/custom/The_SBrick_BLE_Protocol.pdf Jo

What confuse me more is the operation voltage Range of 3,0 to max 6,0V Why, when Spike (Prime & Essential) uses a 7,4V Accu ? Why not design it up to 9,0V to can use it also with the C+ Hub ? Now PWM Range will be reduced tp 0 .. max. 60% at 9V, so regulation will be more limited

Hello, I want to learn PyBricks that seems to be a MicroPython Version. I'm novice here and want to find Information on Basics of the Language. For example : from mindstorms import MSHub, Motor, MotorPair, ColorSensor, DistanceSensor, App import hub as hb from mindstorms.control import wait_for_seconds, wait_until, Timer from mindstorms.operator import greater_than, greater_than_or_equal_to, less_than, less_than_or_equal_to, equal_to, not_equal_to import math So when I need some Functions of Library math, then I have to include them by import. But what is then difference to from mindstorms import MSHub ? And what is intention of from mindstorms.control import wait_for_seconds ? What is difference to from mindstorms import MSHub ? What commands are still included and has not to be imported ? Where can I find a Table/List/Overview about this ? Where can I find a Table/List what Modules are available for import and what they contains ? Sorry for this Newbe Questions, Jo

600mAh and Education reminds me to the Energy-Meter with 2 PowerFunction connectors. Will there be replaced the PowerFunction Energy-Meter by a PoweredUp Version ? 600mAh (3,7V Li-Ion) instead 200mAh (8,4V NiMH Varta HR 6F22) and 2 Ports, one to a Hub like Spike/Inventor and second for a Motor, maybe ? The short-term confidentialy for internal & external photos and an User-Manual ends 180 days after 29.04.2021 (noted in the document Cover-Leter), so arround 01.Nov 2021 we should know more.

Hello, There might be a new HUB in the Pipeline : https://fccid.io/NPI47591/Label/Label-and-Label-Location-5227949 Referenced Hub No. 7 / Hub No. 12

Hello, Is there a description what ARM controllers you are using on your boards ? Are there also available Schematic diagramms ?

Hello, Will there be available an Document update with the Barcodes introduced since August 2020 ? Jo

Hello, An corrected schematic diagram can be found here : http://www.robotika.sk/mains.php?page=/projects/lego/tower/index.php Google-Translate help to read Czech Description Jo
