Platform ST STM32: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Vendor

RemRam

Please use remram_v1 ID for board option in “platformio. ini” (Project Configuration File):

[env:remram_v1] platform = ststm32 board = remram_v1

You can override default 3D printer controller settings per build environment using board_*** option, where *** is a JSON object path from board manifest remram_v1.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:remram_v1] platform = ststm32 board = remram_v1 ; change microcontroller board_build.mcu = stm32f765vit6 ; change MCU frequency board_build.f_cpu = 216000000L

3D printer controller supports the following uploading protocols:

  • blackmagic

  • cmsis-dap

  • jlink

  • serial

  • stlink

Default protocol is stlink

You can change upload protocol using upload_protocol option:

[env:remram_v1] platform = ststm32 board = remram_v1 upload_protocol = stlink

Debugging - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

3D printer controller has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Description

Arduino

Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences

CMSIS

The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. It simplifies software re-use, reducing the learning curve for new microcontroller developers and cutting the time-to-market for devices

libopencm3

The libOpenCM3 framework aims to create a free and open-source firmware library for various ARM Cortex-M0(+)/M3/M4 microcontrollers, including ST STM32, Ti Tiva and Stellaris, NXP LPC, Atmel SAM3, Energy Micro EFM32 and others

STM32Cube

STM32Cube embedded software libraries, including: The HAL hardware abstraction layer, enabling portability between different STM32 devices via standardized API calls; The Low-Layer (LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiency

Upgrade your 3D printer from 8bit to 32bit

32bits is the future of 3D printing. The latest marlin had ported to stm32 board,everything works, stable and smooth,have BLTouch,etc.
1)Use the easiest IDE tool that I developped for Marlin STM32 instead of arduino IDE;
2)source code link
https://github.com/Eryone/STM32
https://github.com/hackaday3D/marlin_stm32/wiki
3)Integrated 5 silent stepper drivers TMC2208,control it through uart.
4)Auto controlled Fan on big heat sink,prevent fan from pulling in dust to motherboard directly.
5)with board monitor temperature sensor, software can control the Fan automatically and protect printed model as stepper driver will reboot while over temperature.
6)lower price than any other 32bit motherboard, almost the same as the 8bit board.

    Iskaliyev Zhanat
    Supervisor: Kolosov D.A. nine0062 Buck converters (stepdown, buck) have become an integral part of modern
    electronics. They convert the input unregulated voltage to a smaller
    stabilized voltage. Buck converters transfer small bursts of power from input to output using a switch, a diode, an inductor, and a few capacitors. Although the

    switching buck converters (SBCs) tend to be larger than the
    linear regulators, they almost always provide better efficiency. nine0062 Manufacturers of APIs based on the analog PWM (pulse-width modulation)
    controller often provide a typical wiring diagram to help engineers quickly create a working prototype of the
    . However, analog PWM controllers, due to their logic of operation, are not
    capable of providing accurate digital control of the output voltage. In addition, the creation of a
    device that includes several IPPs at once with one control circuit is quite problematic and not economically viable. You can solve this problem using digital
    control implemented on the basis of a microcontroller. To date, inexpensive 32-bit microcontrollers (MC) of the STM32F103 family with
    clocked at 72 MHz have become widespread. These microcontrollers have 64kB of flash-memory and 20kB of RAM
    , which allows you to load a fairly large amount of code into them. These MKs are equipped with
    four 16-bit timers (65536 values) with the possibility of pulse-width modulation.
    Also in the MK there are 12-bit analog-to-digital converters (ADC), with an input range of
    voltage from 0 to 3.
