    new master and slave to be substituted (1 master 2 slaves) (slave at right is ok)



  • NSCE repo

    Some time ago I remove WebCLGL JS library project from GitHub... But now I have decided to share it again and something better as NSCE which has included NCLGL (WebCLGL totally ported).

    As gratefully to people that love technology instead the money, at that time he made me feel ashamed not to share with them.

    (Don't use for something that involves the loss of privacy and the rights of ordinary people or for simple economic gain)
    Enjoy it ;)

  • two slaves sending

    3drobert10/18/2021 at 15:59 0 comments

    I have replaced the two transistors that going from slave to master by simple diodes and finally work.

    I thinked I was problems with ST levels on RC1 (as MISO) and I replaced this by TTL using another pin but it not was the problem and either other causes that I thinked and tested...

    I need to pause this project sometimes (no much time) because I have multiples ownmade parts and these parts have brought me many headaches and many coding time and I need stop and take this long-term project with many calm, no hurries refactorings to easily understand any part after a long time and allow me touch new interesting projects too :)

    I will need to make new clean PCBs soon. These are already somewhat touched and exist new small changes too

    I'm having some problem to detect slaves when I connect both but not when I connect only one. They have even the differents IDs and work individually but not work when they are together.

    I'm using custom protocol to master-slaves communication, to use any pin that I need and to have completely free the I2C, SPI, UART... pins, to use without problems a MPU9265 (I2C) or ESP8266 (SPI)

    Some resistors corrections

  • some problems

    3drobert09/20/2021 at 00:24 0 comments

    some old printed PCB looks like a minefield (less varnish sprayed) and needs some fixes.

    I have made some correction on the tester too :)

  • selector for sensor type ADC or MPU

    I added some feature more in the new printed slave

    clock come OK too :)

  • simple pendulum

    3drobert09/14/2021 at 21:13 0 comments

    I'm going to test first learnings making the typical pendulum test. But I have only 1 slave now (1 sensor=MPU & 1 actuator=servo). I need other slaves to offer more sensors (without actuators for this configuration).

    I wan't overload slaves making many things and anyway I will need to add other slaves with different sensors (ADC, etc...).

The idea of using multiple small MCUs instead of big one always was on my mind. The hardest part is to get them talk to each other.

I try to divide the work as much as possible so that the master only has to listen to the data of its associated sensor from the slaves and send it all via WIFI to the PC. And receive the action also via WIFI and indicate it to the slave that has that action associated with it.

Even one of the 3 MCUs of the slaves is just to coordinate the other two which are one MCU for the gyroscope and the other MCU for the servo. So that the information is quickly available and flows without much of a jam in making calculations when the master requests things from the slaves.
I have activated PLL to achieve 48MHz too
