STM32F411 / Bootloaders / Mecrisp Forth / Blackpill

This video will introduce the STM32F411 Arm microcontroller and the operation of the three on-board bootloaders. Description of the pin out and control push-buttons will also be covered. The STM32F411 is a Cortex M4 microcontroller which is a step up from the familiar Bluepill.

Great vid. Particularly helpful how you distinguished the 3 ways to upload code. That was baffling when I was getting started with the blue pill. Thanks for sharing.

Clear, concise and to the point on the STM32 ARM Cortex M4 microcontroller with various programming and debugging options. You've helped me make an easy decision on which microcontroller platform to choose when developing embedded applications for my clients. Thanks for your hard work and your video.

Excellent and much educative video. I use the STLINK myself.

Thank you for your clear, concise, and useful instructions!

Great video and I have had the parts for years. One tip - never use a pencil as a pointer as you will have high impedance leakages.

[PeterForth]

Thank you very much 0033mer another great forth video. A great thanks to Matthias Koch outstanding creation. Mecrisp is a lighthouse in the dark, and beats all commercial forths.

I would like to congratulate you and say thanks for sharing your knowledge in such a clear way!

Thanks for the video. You came like an angel

[randallyoung]

Thanks for posting, just what I needed today ...

Nice video! If I may, I would recommend to upgrade to 2.5.3!. And for serial communication I think "folie" is more handy.

Amazing video! WeAct (original designer of this board) should be linking this on all their store pages.

MicroPython on this board is a lot of fun too, editing main.py directly through the USB mass storage interface is luxurious.

The mecrisp words .mode, port.a, config? etc are not available in the vocabulary of Mecrisp-Stellaris 2.6.5 . 😞
Do these words reside in a special vocabulary ?

[rompipelotas]

very clear do you enable the external memory soldered on the pads of the board and where to go to enable it ??

Hi
I need help.
I have a stm32f chip with 48 legs.
Leg 44 is the boot where I should give it 3.3V. But which side is the 44th leg? I can't find a description of this anywhere.

I'm fine until 7:05 where it says Available DFU devices, which is blank. Windows Device Manager shows a STM32 BOOTLOADER under Universal Serial Bus Devices. I have been able to install and run the blink program using the Arduino IDE so I expect the board and the cable are good.

Sweet! I picked up a 3-pack of Blackpills, and am having a blast with Forth! (Haven't used it since the C64's Blazin' Forth!)

One question, though... How did you get the MCU to 100mhz mode? When I run the command from the Mecrisp folder (100mhz.fs) the thing hangs so hard that even STM32Cube loses connectivity to it.

I love my black pill since it is a powerful all purpose machine.

[francoisp]

Thank you for that vidéo and explanations

[egehanceylan]

I am using the STM32F411 processor and I could not find any data on the boot time. Could you guys help please?

[blahman]

I connected the stlink and stm32f411. It does not connect. Any help?
