Hi Benj, Hi Benj, would it be possible to have the right ".aia" file of the V2 version of the robotic arm (AllCode ARMv2) allowing to program under appinventor? The one given by the QRcode corresponds to the V1 version and there is only an example file "RobotArm2_Buttons.apk" in ...

Hello Benj,
Do you think you can answer my request?
Best regards

Bruno

Hi, I just tested 2 repairs on two of my allcode. The first one was to remove the 10uF smd C13 capacitor; this is very delicate and the tracks are very very fragile! You have to be very well equipped to do the maintenance. I damaged the track and I had to do a strap from the "Vcap" pin of ...

Hi Benj, I would like to take advantage of all the macros in the api and act on the Allcode hardware. It would indeed require an additional function on the API interacting with the API Target method /Formula AllCode Sim functionality. This would allow to test all the codes with labview, python, flow...

Thank you very much Benj.
I love this Formula allcode and your responsiveness with Flowcode V9
Best regards

Hello, I am now using Flowcode V9 and I have just noticed that there is no possibility to choose the IR sensor simulation mode. Screen Shot 12-14-21 at 11.17 AM.JPG The simulation on flowcode V7 gave excellent results to within 1mm. The measurements in real life also gave a rangefinder with an accur...

Hello, would it be possible to have a modification of the Formula AllCode API so that we can send an external command in USBserial and transfer it to the Formula AllCode hardware in simulation. The idea is to be able to test the commands coming from a terminal (here Termite) or from a windows applic...

Miracle of the beginning of the year ! Thank you Ben.
They all came back to life!
Now my students will get their allcode on the classroom radiator!
Is there a repair solution (change of very specific SMD electrochemical capacitors)?

Bruno

They have all worked fine since 2012-2017. The recharge works and the BT connection too. I have just compared the signal at the terminals of the capacitor C28 of two allcodes and they seem identical: same rise time and maximum voltage. I'll try to keep them warm! But this is not a lasting solution ....

Hello,
I have 3 allcode out of 11 which cannot be programmed anymore; the red led no longer flashes. I can no longer program them either in USB or in Bluetooth. Is it about the 10uF reset capacitor C28? Can you confirm it to me?
Best regards and happy new year!

Hello, I am doing tests with a RGB WX2812B and an ECIO40. The test programs work, but the signals at the oscilloscope do not match at all. Here is a statement for a ring of 8 LEDs all lit in red (G = 0, R = 255, B = 0). Everything seems correct but here are the measurements for the low states: T0H =...

Hello, Some time ago you modified the model of the "standard servo" and "micro Servo" in order to allow to reverse the direction of rotation according to the manufacturers and I thank you for that. Can you now make a new modification to simulate continuous rotating servo motors (...

Hello, I still haven't solved this problem. Do you have a suggestion for me? The following popup window does not open and flowcode does not convert 3d files to a "mesh" file, so no link is created in "mesh". I can, however, upload a mesh file created with another PC! Screen Shot ...

Hello, back for a second modeling of IR sensors. First of all, a small modification concerning the exponential type equation: the equation which is best suited for a distance range from 15mm to 170mm is rather N = 2991 * exp (-0.04 * d) with d in mm. The coefficient of determination R² is 0.957. (I ...

Hello, on a pc, the conversion of STEP file to mesh works well but the converter does not launch on the second PC and the result is an image without link Screen Shot 02-06-20 at 05.17 AM.PNG ... I tried to inhibit the anti-virus, reinstall flowcode but nothing helps! An idea? thank you in advance Br...

great! I still have two questions Does the "IR simulation mode" parameter also work with line following sensors or only with distance sensors? What documents, video or tutorial help you understand how to modify a component such as the "Formula AllCode API" knowing that this compo...

My version of flowcode is 7.3.0.7 and I am using the update of the formula flowcode API component obtained here:
viewtopic.php?f=41&t=21574

Ok, FA component appears as a white square with my file but i can't add the formula allcode API component

maybe "unlock"...

sorry but the component no longer appears in the components bar, nor in the search bar.
I unlocked the file, put it in the "components" directory and restarted Flowcode ...

I'm on flowcode7. Thank you so much!

Hello Benj, I am currently working on the infrared sensor of the allcode. In simulation, the response is linear and responds to the equation: IR = 4290-3*distance. In practice, the answer is of exponential type and responds to an equation IR = 4890 * exp (-0.57 * distance), then I modify my program ...

Hello,
Everything seems to work perfectly. Thanks again
Bruno

It still does not work...
I do not understand where it comes from

Hello Benj, I have a problem with simulating a click event and moving an object. Execution of the event macro does not respect the time (1s) between the two object movement functions and executes the two functions after 2s! It works fine if I do a test with a non-event macro. Am I doing something wr...
