You can use Arduino IDE or VScode with Arduino extension, you will just need the Arduino_Core_STM32 from github. If you use the STM32CubeProgrammer you don,t need that FTDI at all, just plug the cable and do exactly same thing to go bootloader mode, the device will show up as HID

@dieSpinnt 4 жыл бұрын

This is a viable solution. But you'll use it exactly till the time when you discover that it is cumbersome and prevents you from using some features of the hardware. With another kind of the same device you can realize a full blown ST-Link programming adapter or other kind of debugging hardware that doesn't disable you from using the full potential of the hardware or any tailored libraries like libopencm3, CMSIS, etc. including a Makefile development solution that is fast and lean. Especially when you are developing USB solutions your boot-loader is in the way. Later, when the product is ready, there is no problem to have a DFU or github.com/feaser/openblt boot-loader for product updates. Please don't misunderstand me, there is nothing wrong with github.com/rogerclarkmelbourne/STM32duino-bootloader and friends, but there are alternatives and better(or different) debugging/development solutions out there, that you will like if you touched them.

Now you get a 32 bit, 100 MHz+ microcontroller with a mind numbing amount of peripherals (and hardware floating point) on a carrier board with the ability to use a proper debugger for the same price. I can't tell you how much time I spent printf debugging with bit-banged serial because the only real UART was tied up doing something else.

I know, right!? Giving away my age here, but in the late 90's early 00's before Arduino existed, I had a play around with a sort of similar device called the BASIC Stamp and BASIC Stamp II. They were PIC microcontrollers that ran a BASIC interpreter, that allowed you to be able to program them with BASIC. Those things costed $50 each in 1999 (yikes!). But, for a kid like me at the time, programming in BASIC was much easier than trying to learn assembly. C compilers existed for PIC's back then, but they were very expensive. I still have the BS2 I bought back then lol. That thing was precious to me, $50 was a lot of money for a 16 year old back then.

Still have a receipt for one hanging around from ‘03. One of the guys in the robotics club I attended at the time was making little breakout boards for the AVR microcontrollers (atmega8 and atmega32) well before the Arduino and I switched to them because they were so much cheaper. Built a theremin like thing for a "make your own instrument" project with an atmega8 in 6th grade and nearly got a zero because my teacher couldn’t believe that I’d made it myself. Fun memories.

Gary, thanks a lot for this very helpful video. I have a blackpill (F411) working as you describe, with both LED and serial port working. I'm programming through the USB interface, using the STM32Cube programmer. I cannot get the USBSerial object to work! I'm wondering whether it's an inconstancy between the blackpill board and the NUCLEO-F411RE board layouts (some incompatible USB setup parameter perhaps). I have the USBSerial instantiation statement at the start of the program, and when run the program never gets beyond this statement. I've tried blocking and non-blocking (true and false arguments to the USBSerial call) but the PC (Windows unfortunately) never picks up a new USB serial device. Have you managed to get the USB Serial functionality working using mbed, and if so, can you post your code? Thanks again for your really helpful videos!

I don't know which evil marketing guy has come up with that kind of confusion-kung-fu for us. The originally black pill was based on STM32F103 like the blue one, featuring mounting holes, one sided component placement and a micro USB connector that doesn't fall off when you look at it at an angle. Also you doesn't mention some "big" features of the blue pill: The 3.3V voltage regulator is very small (current wise) and you will most likely have the wrong pull-up resistors making USB-connections a gamble. That's no problem at all and easy to fix for that price, but better to keep such things in mind. So whats wrong with this "thing" ... should we call it Black Pill v2 ... Black Pill 401?

That USB disconnects when the MCU restarts and it has the same effect as yanking off a USB component while it is still in use. The serial terminal on your computer may crash or at least you will have to go though the connect routine again. When you are developing, you flash and restart the MCU very often and having to clear the error prompts and reconnect every time is a pain.

My experience with the black pill has been very promising. For the cost, it's remarkable. A few dollars only and you get 84Mhz clock, an FPU and buckets of functionality. I have been leery of the tools like the ST-MX where I saw something like this in the Motorola tools a few years ago - these were expensive and kind-of-hard-wired you into a programming model that hid the details far too much (for mine).However the ST MX toolset enables you rather than channelling you. Initialization and start up configuration is a snap. Having spent the last few years with the PIC32 and ICD3 plus a $1,000 compiler (back in 2009) these tools are unprecedentedly inexpensive and versatile and enabling. I still have not got the ADC in the PIC32 running properly yet. It's just so complex. The ARM STM401ccu6 ADC is 12 bits compared with 10 bits for the PIC - 4 times the resolution (on a $5 board!) and with black pill and ST-MX I simply say I want the ADC to run, interrupt driven and I'm pretty much done. (well almost!)

Regarding speed of these MCUs I can say that the STM32F4 is a lot faster than the STM32F1, more so than the frequency might suggest. The F1 is seriously crippled by the slow flash access times. The F4 has some simple caching going on and also a wider bus to the flash making it way faster than the F1. Something like 2-3x faster at the same frequency.

@@GaryExplains Exactly. A native interface for sd cards is spi . Doesnt matter what microcontroller you have as long as it has spi you can communicate with an sd card.

It is apparantly a bit easyer to implement too if you are going with the more advanced IDE's.

Thr black pill name was already used by a stm32f103 board. It just has some different passives on the PCB and a different Vreg or something. It was to fix some design issues on the bluepill but then "they" just fixed the bluepill anyways. All cortex m3 boards

Hi Gary. I've for a request and plea for a video....Support for non-FOTA NONOS ESP8266-01 WiFi module ended some time ago, in that the "eagle" based bin files were no longer included in the SDK. There seems to be vague instruction that these bon files can be compiled e.g. @t (python utility) and usually from in Linux. It would be great to be able to flash the ESP-01's with the latest firmware as it's less buggy and gives good new AT commands to the module. I am thinking about the 1MB (8Mbit) 'black' silkscreen modules. Could I appeal to you technical skills to make a video on this to allow the many millions of these modules to operate at a better level. I really appreciate all the help you give us and would love it if you can crack this problem. Thanks.

So to get this straight, let's take a very powerful embedded CPU and make it work with shitduino IDE to blink an LED. Great, now I've seen this too. Amazing, and you're going to debug your code how?

I wouldnt bother with this one. Get yourself the Arduino Pro Micro based on the ATmega32U4. There are a few great libraries for it and Arduino IDE. Its VERY easy to use and you can simulate 4 Joysticks on just one Pro Micro. I have built myself a Joystick this way. I have 6 Axis 28 Buttos and so on...

An online compiler...? I'm trying to suppress the urge to vomit... I sure hope there's another way to get code onto these things. These are ARM based chips... shouldn't there be a way to GCC to emit code for them...? Please... the OS is nice, but all I really ask is my choice of IDE, and a set of register descriptions... The boards I ordered are going straight into the trash if I've got to use their online tool.

@GaryExplains 4 жыл бұрын

Yes there are lots of alternatives including using GCC etc, the mbed OS compiler is just the easiest to demo in a short video.

As USB/Serial adapter, I'd recommend the "golden CH340G" (good search term) instead, as it can deliver 150mA instead of only 50mA from that red board. While 50 mA may be enough for some boards, it is quite low if you go into MCU chips with Wifi (like ESP32 and ESP8266).

Why not use the much better esp32 or 8266. the 32 is dual core and much faster. It comes with 8 touchpins by default. They only cost 1 dollar more at 5.00. On top of that you can run micropython on the esp32 and 8266 and it is much easier /quicker to program.

It has USB, but to program it one has to jump through a dozen hoops, no wonder all the electronics I bought recently sucks a big one (meaning morons so entrenched in the past designed it so that all the advances in hardware are brought to nill). I wonder why they haven't brought back videocassette recorders or 8-tracks.
