suggestion if you are struggling with the STM32 board #morsecodetutor #mct

It looks like several people are struggling setting up the blue pill type boards. I have a suggestion for those of you that are losing sleep trying to get your boards working. I should back up and state that I had no first hand knowledge of these boards prior to W8TEE mentioning in a post he was going to use them for this project. In one of the earlier messages about this project, Jack mentioned the Maple Mini variety of the STM32 boards. That got me looking to see why. There was a very good reason to call out the Maple Mini specifically. That board was developed by Leaf Labs as one of the first, if not the first, Arduino compatible boards using the STM32. They built it to be as Arduino user friendly as possible. Skipping ahead to why that matters, that board has onboard USB and a preloaded bootloader. You still need to add the board to the Arduino IDE but it is as close to plug and play as there is in a STM32 board. Unfortunately, Leaf Labs is no more but according to https://wiki.stm32duino.com/index.php?title=Maple_Mini , a good read if this is of interest to you, AliExpress seller Baite sells a good quality clone of the original. The wiki links to a listing for 5 pieces, here is the link for one board https://www.aliexpress.com/item/leaflabs-Leaf-maple-mini-ARM-STM32-compatibility/1400667476.html With the cheapest shipping option, in the US you're looking at about $5. It took 15 calendar days to get to me in EN52. I didn't time myself but from ripping open the Chinese shipping bag to having the board blink at my command seemed like hardly enough time to hard boil an egg. If you are comfortable with this sort of thing the blue pill boards give you a ton of power at an unbelievable price. However if this is a challenge to you, I humbly suggest you spend a few more bucks and order the Maple Mini clone.
Disclaimer I am far from an expect on this topic. There is a reasonable chance following my advice will lead to heartbreak and poverty. If you do what I suggest and you burn your house down or turn your dog into a cat you should probably rethink your life choices and wonder why you took advise from a stranger online.

Hi. Thanks for this information. I've played with one then two blue pills. Using the 3 load methods I can load but haven't seen execution. I'll keep trying but I now have some Maples on order. Thanks Ray ae5hn

Hi,
I've had good experiences with these boards. Pretty much plug and play with the STM32Cube toolchain, and the STM "official" Arduino toolchain. Have not tried them with Roger's Arduino STM32 toolchain (at the moment seemingly the most popular Arduino toolchain), but imagine they should work with the ST-Link programming mode. A couple of examples are: https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-nucleo-boards/nucleo-f303k8.html https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-nucleo-boards/nucleo-f103rb.html But I'm coming up to speed with the Blue Pill as well.

Trying to compile mtc code and not having any luck I think I have all the libraries installed now but the compile goes nowhere and exits out. It does not hilite any line of code so I have no idea what to do now. Here is what I get: Arduino: 1.8.9 (Linux), Board: "Generic STM32F103C series, STM32F103C8 (20k RAM. 64k Flash), STLink, 72Mhz (Normal), Smallest (default)" WARNING: library Tone claims to run on (avr) architecture(s) and may be incompatible with your current board which runs on (STM32F1) architecture(s). /home/david/Arduino/libraries/Tone/Tone.cpp:126:4: error: expected constructor, destructor, or type conversion before '(' token ISR(TIMER0_COMPA_vect) ^ Multiple libraries were found for "Wire.h" Used: /home/david/Documents/arduino/arduino-1.8.9/hardware/Arduino_STM32/STM32F1/libraries/Wire Not used: /home/david/Documents/arduino/arduino-1.8.9/hardware/Arduino_STM32/STM32F1/libraries/WireSlave exit status 1 Error compiling for board Generic STM32F103C series. This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. This is getting very tiresome. Happy for any assistance. Dave

Also, does your Wire.cpp file specifically mention the LeafLabs in its header? If not, you're using the wrong Wire library. Mine compiles without error for the same Generic board. I've attached a copy of the code just in case they are different. Jack, W8TEE

Jack that is the same tone library. My wire lib does not say anything about leaflabs. Where did you get your wire lib? What is it called? Thank you Dave

That library was included with my install of the STM32 system. I have attached a copy of both Wire and WireSlave. Jack, W8TEE

Multiple libraries were found for "Wire.h"Hi David, This may be one of those classic helpful replies I see so often on programming forums: "Well... It compiled for me". Actually I'll try a little harder than that. I compiled Jack's Morse Code Tutor with Roger's Arduino toolchain. (Yes, I caved in and became a complete wimp and installed the toolchain that works with Jack's code, rather than fighting the brave fight to force it to work with another toolchain). (I still may do that as a learning exercise at another time). First, when I compile the code I get the same message about the Wire/WireSlave libraries, so that may not be an issue. I did a global search for all the Tone.cpp files I have on my computer. I have one in the /Arduino/hardware/Arduino_STM32/ toolchain directory and another in an /Arduino/hardware/heltec/ESP8266/ toolchain directory. Best I can tell the ESP8266 version is not entering into the picture. This is the version it looks like is in Roger's package: https://github.com/rogerclarkmelbourne/Arduino_STM32/blob/master/STM32F1/cores/maple/tone.cpp The one thing I noticed in your log file is: "/home/david/Arduino/libraries/Tone/Tone.cpp:126:4: error". It looks like you have a "Tone.cpp" file installed there also. I'm not sure, but is is possible that the Arduino toolchain gives preference (via a search path mechanism) to libraries in the generic /Arduino/libraries/ directory? Maybe uninstalling (or simply removing) the generic (AVR 8 bit) library would be worth a try. Hopefully this helps. Tom, wb6b

Doug,
I have ordered a few from Wavgat store (experienced on this kind of boards) https://www.aliexpress.com/item/32525208361.html Your link part number is STM32F103CBT6 and mine is STM32F103C8T6 which is cheaper and has a crystal on it. Just one letter is different, but which one is legit?

Both are legit. The “CBT6” has more memory than the “C8T6” version… no other differences. See: https://www.st.com/en/microcontrollers-microprocessors/stm32f103.html

First, what op system are you running and do you know the maker of your board? Second, what happens if you make this: #define WIRING the first line in the MorseTutor.h header file. Jack, W8TEE

Jack when I add #define WIRING to morsetutor.h I get exactly the same errors. My os is linux mint 19. The board is standard blue pill from ebay. No idea who made it. Works fine with blink sketch.

David: Adding the #define would have been a bad hack anyway! I do not have a Linux system, so that's a problem. It clearly seems to be an issue with the Tone and/or Wire libraries. Perhaps someone else running Linux has some ideas?? Jack, W8TEE

I am rather new to programming and I am seeing references to "toolchain" in some posts lately.
What is a 'toolchain' and how is it used? We newbie programmers would like to know... maybe. PJ, N7PH

It's an old timey way to do programming. Without an IDE, you need to write a program, (c,c++, fortran?), and use a developers compiler and library linker to 'make', an executable. to load to your memory chip.

Hi,
If it claims that tone is for AVR rather than STM32 two possible causes I see.
For some reason unknown the tone library in the STM32 directory has been replaced with the AVR version. Try downloading again, maybe rename the original file first so you can see if there is a difference.
The compiler is still looking in wrong place/order. Try renaming the AVR and any other versions there might be except the STM32 version.
