Any time I ask a really specific question here it always seems to go by the wayside. But what the heck -- it's Friday, it's late, and my @#$% processor won't go to sleep!!! Anyone have any mileage with the ST Arm Cortex parts and sleep mode? I've got a STM32F303 that doesn't really need it that goes to sleep beautifully, and I've got an STM32F051 in an application where low power is...

Maybe someone can help me out with this. I'm looking at the data sheet for the STM32L412xx trying to find details on the mapping of the input voltage range to the 12 bit code produced. It might appear that the Vref+ and Vref- pins define the exact range, but it seems unusual that it could be equal to the power rails. With Vref+ = 3.3V and Vref- = 0 volts does 0V on the input

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...

I'm pleased to announce that the tutorial titled "Ada and SPARK on ARM Cortex-M" got its second edition: http://inspirel.com/articles/Ada_On_Cortex.html The tutorial was extended and now targets four popular development boards: - Arduino M0 (or Genuino Zero) - Arduino Due - STM32 Nucleo-32 (with F0 chip) - STM32 Nucleo-144 (with F7 chip) The tutorial explains how to write Ada/SPARK ...

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...

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...

I want to test the I2C protocol between two STM32 (STM32L152RC) microcontrollers. Can somebody guide me on how to do it or suggest tutorials? I have seen some online portals where they are communicating between a microcontroller and any sensor. That I have done already. Now I want to test it between two MCU boards.

See: http://mcu.st.com/mcu/inchtml.php?fdir=pages&fnam=stm32 (and: http://www.freertos.org/portstm32iar.html :o) The Cortex-M3 marketing has trumpeted greater interoperability between vendors as one of the M3 selling points, so it is interesting to note that the FreeRTOS.org demos for Luminary Micro and STMicroelectronics Cortex-M3 parts use exactly the same port code, while the port...

http://www.microcontroller.com/news/arm_cortex_stm.asp STMicroelectronics has introduced the new STM32 microcontroller family, based on the Harvard architecture ARM Cortex. Article includes a roadmap and a useful chart of the STM32 low power operation, which is as low as 0.5mA/MHz. Regards Bill Giovino Executive Editor http://Microcontroller.com

Group, This is not spam. I am looking for a respectable and reliable company to do some business with. My company has a design and schedule in mind that cannot be achieved without some external help. Specifically looking for a firm with experience using Micrium tools on STM32. My design lends itself to use of thier RTOS, File System, GUI and USB-MSD software.

Hi! Does anyone know of a tool that will generate svf files (or something simillar) for ARM cortex based micro's. I've actually got an STM32 but which flavour of cortex shouldn't matter. This is the means by which a production JTAG interconnection tester (JTAG technologies in this instance) programs CPLDs, micro's or other simillar stuff. At the moment we are just using an open source co...

I am still trying to sort out a set of tools for the STM32 (and possibly other ARM processors). I know there have been several discussions on here. I have very little money as I am essentially a hobby user. Raisonance RIDE7 and the ARM toolit provide what appears to be a good IDE and a version of the GNU ARM tools. It is free and unrestricted. So far I quite like it. To program and debu...

(Not to start a tools war but) I'm about to start a project that will use the STM32 ARM from ST. IAR and Keil both supply high quality tool sets for the STM32. I've used both toolsets' evaluation copies. I believe I'd be satisfied buying any one over the other. Can anyone make any comments why one might be better than the other? At this point, it's a flip of the coin. I'd like t...

Hello... I am using the Cortex M3 ARM Controller STM 32, And my device to be interfaced is a 5V logic which is having an SPI and needs a signal which is 1Mhz I can make a 1Mhz signal in controller using PWM and it is having an SPI Hardware but both out put is 3.3V but the PINs of STM32 is 5V tollerable. so the output from the device can be directly connected or with a resistor in it.

Hi everybody- This question comes up from time to time from various posters but it never gets an answer that fits my specific needs. Here goes: Would anyone be able to recommend a free embedded basic interpreter with C source code? My intended target is the STM32 which probably has enough RAM for small programs. My intent is to create an embedded controller board with a serial p...
