Make sure to install the Arduino Zero board to get the compiler, which the board manager called “Arduino SAMD Boards”.
Now to fire up the old trusty Arduino app. It keeps repeating this message, looks like it worked. It appears to detect the STM32 correctly:Ĭongratulations, you have installed the STM32duino bootloaderįor more information about Arduino on STM32

The instructions for flashing the bootloader are for Windows or Linux, but I’m on macOS, so I found this to try instead: stm32loader. Wire up TX, RX, GND, and 3V3 to a USB-to-serial adapter: Stm32duino gives instructions for the newer “black pill” board, connecting RX to PA9 and TX to PA10, where are these pins? Spotspot gives a hint: they are PA9 and PA10 are labeled A9 and A10 on the board. When I set boot0 to 1 high and boot1 to 0 low, when powered only the power LED illuminates. This took longer than expected, due to a n00b mistake of not orienting the header straight and nonetheless soldering all the pins had to desolder with copious amounts of flux:Īnd clean it up then reorient correctly, but all’s well that ends well:įollow the instructions in Burning the bootloader. This is because you must burn the bootloader. The red power LED turns on solid, and the green PC13 LED blinks continuously. What do I have? Let’s try just plugging in the micro USB and powering it:
The Maple mini clones don’t require flashing a bootloader. Stm32duino’s wiki page for Blue Pill has more information. This board will not be usable when you receive it, as it does not contain a bootloader. The device I ordered looks a lot like the what they call a “Blue Pill”. There is an active community and support forum at. Hardware files to support STM32 boards, on Arduino IDE 1.8.x including LeafLabs Maple and other generic STM32F103 boards”. How about Arduino? Found this useful page: Sunspot: Experiments with the Arduno IDE connected to a generic ARM board - containing an STM32F103C8T6, which points to [)() described as “Arduino STM32. I’d like to run RetroBSD, but it targets the Microchip PIC32 microcontroller (128 KB RAM, 512 KB flash), maybe it can be ported to the STM32F1? There is some discussion on the RetroBSD forums: STM32F103ZET6 board for RetroBSD?. What is the T6 in STM32F103C8T6? Digikey has 6 matches for STM32F103C8, so T6 appears to indicate the packaging not important for programming specifications.ĭatasheet: STM32F103x8 STM32F103xB Medium-density performance line ARM®-based 32-bit MCU with 64 or 128 KB Flash, USB, CAN, 7 timers, 2 ADCs, 9 com.

The full part number STM32F103C8T6 decodes to C8 = 128 KB flash, 20 KB RAM, 48-pin LQFP: The F1-series has evolved over time by increasing CPU speed, size of internal memory, variety of peripherals. The STM32 F1-series was the first group of STM32 microcontrollers based on the ARM Cortex-M3 core and considered their mainstream ARM microcontrollers. From Wikipedia, the 103 model (STM32F103) is focused on performance: Could’ve gotten one of those or the cheapest ‘F0 but the ‘F1 kit was inexpensive and I decided to go for it instead. The STM32F4 seems to be one of the most popular, it even has its own subreddit /r/stm32f4. Several versions run up to 180 MHz, with 2 MB of flash and up to 364 KB of RAM (in the case of the STM32F469).īut the brand-new STM32F7 - part of the new Cortex-M7 line of parts - goes even further, with 216 MHz maximum operating frequency, 2 MB of flash, and 512 KB of RAM. The STM32F0 has a famous big brother - the STM32F4 - that’s one of the most capable Arm Cortex parts ever built. This is actually a different chip than Jay Carlson covered, ST Micro’s STM32 32-bit microcontroller product lineup ranges from the low-end STM32F0 featuring an ARM Cortex-M0 up to the STM32F7 with a Cortex-M7F: Specifically, the STM32F103C8T6 ARM STM32 Minimum System Development Board Module Forarduino board from Aliexpress for $1.85 (not bad for the full development board). Inspired by the The Amazing $1 Microcontroller - Jay Carlson, I purchased a STM32 microcontroller.
