      Wanted to leave this here I currently created this PCB to work with @maghac his code. The prototype on the breadboard worked so now it is being produced. As soon as I have a working model I will post the gerber files so anybody interested can also order it for manufacturing. The weird shape by the way is because of a enclosure I am using this one (the 100 X 68 X 50).

    • RE: RGBW controller design issues

      Thanks all for your input. It is going to be back to the drawing board for me. At least I learned a lot about the mistakes made here. I did try the setup on a breadboard before and that worked but that was with a arduino pro mini so not with the seperate chip. Aw well lessons learned and let's get going for the next PCB. Probably gonna post it here before ordering it 😉

      @hard-shovel
      The chip is this type
      0_1534401813418_IMG_20180417_173338.jpg

      I am externally programming it and then soldering it on the board. I did try to use a 10K resistor between reset and 5VDC source, it did not work unfortunately. Do I also need to use a 0.1 uf decoupling capacitor with it as well? I am afraid that I maybe fried the chip in the meantime... Also I am not very certain about the NRF24L01 + PA + LNA SMD antenna. I think I am going back to the drawing board and design it for an non-SMD antenna.

      Thanks,
      Jim

      @hard-shovel That is probably going to be my problem.. I will try it this afternoon! thank you very much for your help! I have been staring blind on the issue! If I am going to disable the pin in fuses is the chip still programmable? That because I thought that the reset pin needs to be pulled low before starting programming to get the chip in a halt state?

    • RGBW controller design issues

      Hello all,

      I hope you could help me with something. I am currently working on troubleshooting my own RGBW LED controller. I have made the PCB's myself but after uploading the software there is no response from the controller. I am using a SMD NRF24L01 + PA + LNA board and I have made the pinout accordingly. Unfortunately I can not for the life of me find the (electrical) issue with my design. I did check everything with a multimeter and find all connections as should be. Am I missing some critical component which you should include with the atmega328p smd chip? I do have the atmega328 p pu-ph chip by the way but I am able to read and write on it so that should not be an issue (I hope).

      I hope that you guys can be of assistance.

      Thanks in advance!

      Kind regards,
      Jim!
