I normally see software source code for these STM32 Discos or Dscovery boards but I cannot seem to find it for this one... The STM32F412 Discovery kit featiuring the STM32F412ZGT6 Anyone know where I might find this one ? Downloaded the Cube patch but I don't think I see the demo in there for this board. boB K7IQ

Hi I have a project where I need to host a CDC on an STM32F microcontroller. The usarts are in use hence the need for the CDC. I have found library code from STs cube which configures the USB to host a CDC. The problem I have is making my application talk to the device. Obviously when a USB to serial adapter is connected to a windows PC a COMx interface is created which can then be connected...

Hi all, I am learning about the stm32f1xx devices, trying out some example-codes on using DMA with the ADC and DAC. However, when reading the information in the reference-manual about DMA, it mentions DMA in combination with Timers! Now, I am a bit confused. As far as I understand it, the DMA is there to transfer data between devices (ADC, DAC, USART, SPI, I2c) to memory wi...

Hello, I would like to use the STM32F207 in order to interface up to 8 can channels by means of the SJA1000 can controller IC. In addition there is need for Compact Flash interface, plenty of external ram and flash memory. The Flexible Static Memory Controller (FSMC) peripheral seems that it could handle these requirements, but I'm not familiar with STM32 and so I have some questions. First ...

Hi So, I have been using a ST Cortex M0 STM32, NXP LPC, PIC32 and also a Renesas RX63. Just for fun. They look interesting as a potential candidate All processors has a bit to set it up in protected mode, so the flash with proprietary IP cannot be read out But, say my competitor wants to dig into my code Is there really such a thing as a safe micro controller which memory is protecte...

hi, I am doing some more work to get to know the STM32F103, now looking in the libopencm3 library and learning from the example code. (using ubuntu as development platform) I am looking at the demo application to create a usb-over-serial interface (usb_cdcacm), as found here: https://github.com/libopencm3/libopencm3-examples/tree/master/examples/stm32/f1/stm32-maple/usb_ cdcacm

Hello, I am new to bluetooth, I want bluetooth in my application to send data send to mobile. I want a Bluetooth Stack which should be port on my microntroller where my other application is runnning. I want to add this lwbt stack on my application to send selected data to Particular Mobile Device. My question is, 1. Is lwbt is platform dependent or independent. I am using stm32 controller, ca...

Hi I want to know the best software tool for comparing the differences in the linux kernel. Actually I have STM32 microcontroller based development board for which I got the BSP in which the Linux Kernel is present. The version of the BSP of the linux kernel is 2.6.32 I downloaded the original kernel with same version from kernel.org Now I am trying to extract the differences betwee...

I'm building some hand-held gear with STM32 and other stuff on a 3.2V supply, with consumption up to a watt or two, and want to use a single LiFePO4 cell with USB charging, and preferably just run directly off Vbatt, with no additional regulator. The Linear LTC4098 looks nice, and Maxim has the MCP73833. Any experience using these, or alternatives to suggest? Hand-solderable would be ...

I'm interested in building a mini gadget that needs a fair amount of computing speed, and I'm thinking of using this Cortex M4 board, powered by a small lipo cell: www.mouser.com/ProductDetail/mikroElektronika/MIKROE-1367 I notice in the data sheet that the maximum power drain is 800 mA at 3.3 volts, i.e. around 2.5 watts. That sounds awfully high--even a fancy smartphone with a multi-g...

Hi We are working on a TCP/IP Gateway. Ideally we would like to use one of the free TCP/IP stacks that ST has made publicly available, but we are also open to 3rd party stacks We do however no know the maturity of any of the stacks listed at the ST website: http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1031/LN1564/PF221027 (click the "Design Resources" tab) Or should we be lookin...

Hi, We would like to announce that the CyaSSL embedded SSL library now has support for hardware-based cryptography and random number generation offered by the STM32F2. Supported cryptographic algorithms include AES (CBC, CTR), DES (ECB, CBC), 3DES, MD5, and SHA1. For details, please see the original blog post, here: http://yassl.com/yaSSL/Blog/Entries/2012/12/27_STM32_and_CyaSS

I'm working with an STM32F205, which I can program and debug with an ST-LINK V2 and the SWD port. I'm using IAR EWARM 6.40 and the C-Spy debugger. Programming, run, stop, breakpoints, etc, all work fine. However, when I set up for SWO debugging, the SWO icon reports that it is set up properly, but I never get any profiling data in the window. The O-scope shows regular activity on the S...

When preparing nonstandard USB firmwares for STM32 microcontrollers, it would be perfect to have a possibility to use a "CUSTOM CLASS", in "Class for FS IP" list in CubeMX. Unfortunately it is not available. I have taken a look into CubeMX, and have found that for example the CUSTOM HID class is implemented in the following way: In the USB_DEVICE_-STM32???_Configs.xml file there are the follo...

Hello, I'm planning to use Bluetooth in a medical device I'm developing. The device is already based on a MCU (STM32) and is powered by mains. The device will provide only the File Transfer profile sevice: it will act only as a server providing one or more files that a client can download (no modifications or upload on the server possible). I would like a bluetooth solution (single-chi...

I'm relatively new with embedded systems and electronics so I might be trying something above my skill level: I have a Nokia N95 cellphone and an ARM mini-STM32 eval board with mini-USB-socket. The problem seems to be that I can use only 4 wires (ID is floating on the board). What can I do to get my ARM-board and Nokia connected? Would a USB hub make either one of these devices a host? ...
