STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on February 25, 2016 at 09:22Hello everyone, i have a circuit where 8 I/O (5V tolarant)pins of my STM32F407(supply is 3.3V) are configured as inputs and are tied to 5V with a 10K pull-up resistor. The I/O as inputs work ok but when a configur...
Posted on February 17, 2016 at 01:15Hello and thanks alwaysI am programming a STM32 Nucleo with mbed and I have a curious situation. If it sounds familiar to you, I would appreciate any pointer, advice or commentI have successfully programmed the nu...
Posted on February 24, 2016 at 15:21Hi,I am using stm32f103vb discovery board. Here i want to access UART1 and UART2 simultaneously. I have done coding in which i am able to transmit and receive data either through UART1 or UART2. But not able to en...
Posted on February 25, 2016 at 04:43Dear all, I have made a board with STM32F105RCT6 to suit my requirements. I want to use the USB as device (Virtual ComPort). I downloaded the USB libraries from ST, where there is a mention of 105 libraries being ...
Posted on February 16, 2016 at 10:36I have a board that has an STM32F405 with the USB pins routed to the USB connector. I had problems getting that board to boot, and I was unable to get it to work as DFU device on USB. One of the possible causes is...
Posted on February 16, 2016 at 20:00Hi.I encountered a problem where I use CRC hardware with optimized code in Keil. I use CRC hardware inside of interrupt routine and without optimization I get correct result. But if I turn optimization on (level 1...
Posted on February 24, 2016 at 16:50Hello!I have a strange problem with the mass storage usb on stm32407ZGt6. Why is it odd ? That's because the same code works on stm32f407ZEt6 just fine. I thought that these cpu's differ only in the amount of flas...
Posted on February 23, 2016 at 17:40Hi i have a doubt about reponse register. The manual says that response register format is 48 bits but the SDIO reponse register is only 32 bits. then what about the remaining 16 bits .may be its sounds stupid but...
Posted on February 24, 2016 at 11:26Hello, we have a simple question. In the device http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/DM00090510.pdf for the stm32f072 page 41 - table 14 colum ''AF2'' describes thre...
Posted on February 17, 2016 at 12:57Hi to all, I tried to build my own acquisition board using a STM32F030K6 microcontroller and I am experiencing problems with SPI interface. At present only microcontroller is mounted, no other devices on board. As...
