Beaglebone Black LESSON 1: Understanding Beaglebone Black Pinout 

Jon Gordon Thanks Jon, and I should have more lessons up shortly. Stay tuned.

If you have a min, what are your thoughts on using it as a 3D printer host and/or controller versus the raspberry pi?

Jon Gordon I think it comes down to whether you need analog inputs or not. For now, the user base for Raspberry Pi is so much greater, unless I need analog in pins, at this point I lean towards the Raspberry Pi 2.

drobbins It is always good to hear High Schools around have Tech Teachers. Keep up the good work.

I'm not using a begale bone board but the board uses the same method you explained the best content to me from this video is how you explained the GPIO channels and the color diagrams. I need to search through your video line and find using ethernet communication I'm using windows 10 WSL 2 to communicate using it to control my cnc plasma table. Keep up the excellent videos.

+KitCox That is really well beyond what I will be covering in these lessons.

+Paul McWhorter I was aware these lessons didn't cover the DRAM. I was asking in general. I was also curious if the 3359 had a memory controller in chip. The Raspberry PI also has a 512MB DRAM. You have a number of lessons on that as well and I want to thank you for all the work. They have brought me completely up to speed on learning the basics on these development boards. I'm learning this because a project popped up that requires me to store a string of data bits in RAM, in particular the string from the Cirrus CS5340 A/D converter as used in HD stereo audio components. For all I have found out so far the RAM may not be user accessible and used by the ARM for program storage only. Thanks again for all the lessons. Kit

+KitCox There's indeed an mDDR/DDR2/DDR3 memory controller integrated on the AM335x. When running linux you're always using the DRAM, it's what you're running from. There are ways to reserve a chunk of physical RAM for your private use but there's rarely a need to do so. I did so for a buffer to automatically store ADC data (using DMA), but since I only needed 32 bytes for that I used a piece of the on-chip SRAM instead.

I like the esp32 and it needs more DIY videos. I do not know why the world needs more Arduino Raspberry Pi videos? Unless the RPi5 comes out?

***** Oh and if you are changing them, can you get them back up please? Oh and is there a way to use the XBee with the BBB?

Hello Again...I may have been wrong. It was probably a glitch on my side. I am sorry for the confusion.

It really is in a different league than RPI and Arduino. That makes it hard to build mainstream community - but if you get good at this device you can make actual commercial products not just gimmicks.
