Ken: Nice job of explaining what's in the ZIP file. For others, I have written other Open Source programs and I tend to follow this convention: The project's header file will list the download URLs for any libraries that are not part of the standard IDE installation. For example, in my MCT, you'll find: #include <stdint.h> #include <SPI.h> #include <Adafruit_GFX.h> // https://github.com/adafruit/Adafruit-GFX-Library #include <Adafruit_ILI9341.h> // Do a DuckDuckGo.com search for these...(I'm done with Google.) #include <Adafruit_MCP4725.h> #include <Wire.h> // Standard with IDE #include <Rotary.h> // https://github.com/brianlow/Rotary #include <Time.h> // https://github.com/PaulStoffregen/Time #include <TimeLib.h> #include <Tone.h> // https://github.com/rogerclarkmelbourne/Arduino_STM32 -- Clark's core library. Install it #include <EEPROM.h> #include <string.h> #include <stdlib.h> #include <stdio.h> #include "Menu.h" // This is our header I got a little lazy here, but I think most know that Adafruit has multiple libraries. It would be very helpful if anyone who submits an Open Source program would use the same convention as it would save some bandwidth on the supporting Forum group. Ken's work also shows that there are multiple files in the project and many of them are named using the *.cpp (i.e., C Plus Plus) secondary file name. I've explained here before that there are numerous advantages to this multi-file project approach over one huge INO file. (I've seen one INO file that was over 10K!) Anyway, thanks Ken for taking the time to explain what's in the MCT compressed file. Jack, W8TEE

Greetings, I have no idea if a person who uses MS-Windows or Mac OSX has to purchase a program to unzip a 7z file archive? On my Debian GNU/Linux system, the program is provided by p7zip-full in the Debian repositories ( # apt install p7zip-full ). If you use MS-Windows or Mac OS, you will have to find the program and pay for it, download it, whatever. Don't forget to check your download for malware, whatever, before you open it, right? To extract a 7z file archive with full paths, use the 'x' option: $ 7z x STMFMorseTutorSimplified007.7z The above command will extract all the .cpp, .h, and .ino files to the STMFMorseTutorSimplified007/ directory. To extract a 7z archive without using directory names, use the 'e' option: $ 7z e STMFMorseTutorSimplified007.7z The above command will extract all the .cpp, .h, and .ino files to the directory that the 7z archive is located in when you extract the files. IF the directory the archive is in already has files in it, the un-archived files will be mixed in it. So if you use the 'e' option, you should probably create a new directory, put the archive in it, then extract the files. For example, I created a new directory called mct2/, moved the STMFMorseTutorSimplified007.7z archive to mct2/, then used the 'e' option to open it. Then I renamed STMFMorseTutorSimplified007.ino to mct2.ino because it is shorter, and fits in the Arduino IDE tabs better. But you can do whatever you want to do. I suggest that you use the 'x' option. That's all there is to it. Leave all the files in that working directory. Perhaps someone with a Mac OSX system, or a MS-Windows system can give details on where to obtain a program which will extract files from a 7z file archive, and how to use it to extract the files from the STMFMorseTutorSimplified007.7z archive? The above instructions were for a Debian GNU/Linux system. I am attaching the Morse Code Tutor 2 program files as a standard ZIP file. The difference in size is trivial by today's standards, but most people know how to unZIP a ZIP archive, no matter which operating system they are using. I have also attached an MD5 checksum for the ZIP file. This standard ZIP archive will extract all the archived files in a directory called mct2/. The .ino file has been renamed to mct2.ino as well, for compatibility with the Arduino IDE. Hopefully helpful?

Looks good.
Downloaded Arduino IDE 1.8.9 this morning. Small problems. Arduino: 1.8.9 (Mac OS X)
uint16 --> uint16_t That sort of thing. No big deal. Working through them now. I'm using a different hardware target which explains most of the issues. Nothing we can't handle! bob wm6h |

I'm glad it is working for you. I think those are the kinds of details people are looking for? There are at least three systems (Linux, Mac, and MS) that the MCT2 can be built on. I think that each system presents its own set of "Blue Pill" problems. Regards, Ken, KM4NFQ "Not Fully Qualified" On Mon, Jul 8, 2019 at 10:59 AM bobolink <rwhinric@...> wrote:

uint16 --> uint16_tI had the same issue when I used the https://github.com/stm32duino toolchain. Did not have issues with the https://github.com/rogerclarkmelbourne/Arduino_STM32 toolchain. I simply added a #define uint16 uint16_t to the top of the file to fix that. There were enough additional issues that I switched to the Roger Clark toolchain, as I had no hardcore reason to use the stm32duino (supposedly official) Arduino toolchain. I also have STM developer boards for client projects, but I tend to use STM32Cube, rather than Arduino, with those. Don't know if you are still in the STM32 family or porting to another processor altogether. Tom, wb6b |

Tom,
Don't know if you are still in the STM32 family or porting to another processor altogether.Another processor altogether. ESP32. Which is kind of a waste as I’m not using the onboard radios at all. All I really expect to salvage is Jack’s “game logic” and expertise in Morse code teaching methods. Bob |

Bob: Actually, I started the Morse Code Tutor several years ago, but went back to it and modified it for the STM32 for the FDIM talk. I made that swtich not so much for the performance aspects of the STM32 (Blue Pill), but for its additional SRAM space compared to the Nano (i.e., 10x) Since then, I've been playing with the ESP32 myself and really like it. In fact, Al (AC8GY) and I liked it enough that we went back in the chapters of the new Projects book and added it and we're using it in several projects. For those who are not familiar with the various microcontroller, this table from the book shows the important differences:
The ESP32 also has WiFi and Bluetooth build into it and is based on a dual core architecture. True, it costs a little more, but this thing can really boot-scoot along at 15x that of a Nano. It is overkill for projects that are not processor-intensive or involve a lot of human I/O, but it's programmable in the Arduino IDE so you can leverage everything you already know without messing with another tool chain. I just wish we had "discovered" it earlier... Jack, W8TEE

Thanks Jack. I’m printing out that chart now.
The floating point performance of the esp32 is, according to this guy, not too great. Even though they have FP in hardware. But it is my goto processor these days. Did you know it has a third processor core just for extreme low power? It’s the Swiss Army knife. bob wm6h |

I have found the ESP32 ADC to be so nonlinear and noisy as to be
essentially useless. Even the spec sheet notes a +/-6% unit to
unit variation in ADC results before calibration. If your project
depends on an ADC, consider another chip or an external ADC. On 7/9/2019 9:17 AM, jjpurdum via

ESP32 ADC to be so nonlinear and noisyThat is good to know. I've started to look at the specs for the ESP32 and it looks really impressive. Great reminder to look deeper past the first glossy descriptions. I was considering the ESP32 for some IoT projects that include analog measurements. Because the ESP32 requires external memory, it is almost always purchased as a module with the extra support chips included. Is the poor ADC performance inherent in the chip or might it be due to the module manufactures cutting corners on bypass and filter capacitors? Tom, wb6b |

The nonlinearity and unit to unit variance are described in the
chip datasheet in the ADC section, so it's not the module
manufacturer. To see the noise, set up a resistive divider or a
pot and look at the ADC output, preferably using the Arduino IDE
serial plotter. Even with a heavy bypass cap, I saw roughly +/-
5% noise. That could be from the module manufacturer and heavy
averaging might give an acceptable result, but it's a real issue. On 7/11/2019 10:44 AM, Tom, wb6b wrote:

Here is a discussion (from Espressif)
ADC Calibration Strange you can’t supply an external reference. Doesn’t Arduino have that? I wonder if turning off the WiFi helps? WiFi transmissions seem to always draw more current than the designers have accommodated for. bob wm6h |

Jack,
A couple of minor comments: I assume you mean ADC not DAC resolution? I think a Teensy3.6 has 3 SPI. FWIW there are also lots of other parameters which might be of interest: e.g. does a module actually have a DAC? But those are often pretty use case specific. I think you've got a reasonable set in this table. Dave L. |
