    I have been working on developing embedded systems for 8 years, and I've greatly benefited from your video. Thank you so much, you have the gift of explaining things well!

    This week has been busy with crating machines, but next week and the following weeks, I intend to publish two to three videos per week on this microcontroller subject. CNC videos will also be published scattered here and there, mainly on equipment that poses a challenge to my customers. I hope you enjoy t his video and I am so excited to make more of these videos in this series. For those of you that are purchasing the books and kits, thank you so much. This really helps me keep going and provides some offset financially to make these videos happen.

    This video introduces you to USART and compares a few other communication methods. I am learning Davinci Resolve, so it is a bit slow, but the features of this software are pretty cool. Hopefully, I have been able to do tracking in some creative ways to convey the content in a new and fresh way for you. Let me know if you like it. It is a bit harder and more time-consuming, but it is fun to see the results.

      Ha, yeah. I'm still learning. I want to create a faster set up to go from camera to editing and back to the camera. I'm still working on getting better with focus. You can see in my close shots the camera doesn't really know what to focus on. I will need to think about how the camera focuses to "focus"" on the work.

    Thanks for this other great video. I really enjoy the effort you are placing in teaching things step by step. Great work !
    I had one question concerning the 74LVC2G241 - This is a dual non-inverting buffer/line driver with 3-state outputs. Can you explain what is the function of this IC, is it to avoid conflict transmission between Rx and TX?

    • @PatrickHoodDaniel
      @PatrickHoodDaniel  2 роки тому +2

      Yes, it is a chip that allows the microcontroller to select which line to transmit or receive. There are three lines from the microcontroller to this chip, the TX, RX, and the signal to select which one to be used.

    I was hoping to find an off-the-shelf solution that does SYNCHRONOUS 9-bit UART at 1Mbps, both as a master and slave. For example, as a Master it would output a 1Mhz CLK, and TX, where the data shifted on the TX pin (changes on the falling edge of CLK) and consists of:
    1-start (low), 9-Data (lsb-first), 1-odd, 1-stop (12 bits total)?
    And as a slave, it would latch what's on the RX-Line on the rising edge of 1Mhz CLK (generated externally)?
    The closest I found is, Digilent's Analog Discovery 2, but it only lists u*A*rt.
    Microchip has a (discontinued?) PicKit Serial Analyzer (DV164122) capable of doing USART.. however, the GUI (2.2) shows only "USART Sync Master". More concerning is that the firmware (305), and Dll (2.4) is from 2009, so even if I buy the hardware, not sure if it will work with Win10. The API examples are for VB2005.

    Hi, is the code written in the book bare metal code or does it use some framework such as the HAL of cubeMX?

    • @PatrickHoodDaniel
      @PatrickHoodDaniel  Рік тому

      Mainly register level. The new series I'm doing on my UA-cam channel is mixed. I do everything at the register level, then using autogenerated code and HAL.

    I just wondered about peoples experiences with breadboards - I've bought a bad bunch - flakey connections and really frustrating. My fault I know for buying cheap but are the expensive breadboards any more reliable?

    • @PatrickHoodDaniel
      @PatrickHoodDaniel  2 роки тому

      Yes, more expensive breadboards are generally more reliable, but pay special attention to reviews and where the breadboard was made. The cost of the breadboard could just be the seller pricing it higher.
