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 November 09, 2017 at 10:11 Thank you for your patronage. I'm using STM32F3348-Discoverywhich has FPU and EWARM. I made calculations like the picture below. I'd like to check if floating point arithmetic is calculated correctly. So,...
Posted on November 09, 2017 at 13:35Hi all,I see an inconsistency between application notes.Here, AN4221 shows that all STM32F303xx controllers have I2C bootloaders:But if I open a different document (AN2606) I see that it is NOT true:Which is true?...
Posted on November 09, 2017 at 13:35Hi,I am porting my code from FREERTOS to RTX on stm32 nucleo platform,but once data transmission starts programs stucks with in second in hardfault handler because of the stack over flow, but if I put some delay b...
Posted on November 09, 2017 at 11:14Hi all,I have an application when I need to reserve 4Kbytes of memory. This size is fixed during the whole life cycle of my application.Therefore my first idea was to create a static memory allocation. But I also ...
Posted on November 09, 2017 at 11:19I'm having a problem on data logging.I use Chan's FatFs R0.08a, SDIO 1 bit mode, DMA and ST standard library, IAR compiler.I save 600,000 data per 200ms in SD Card using CSV format. It need about 33hours.If I try ...
Posted on November 08, 2017 at 21:05In the STM32F030X8 datasheet the PortB pin 15 alternate function AF0 is both SPI1_MOSI and SPI2_MOSI(see table 13 on page 35 of en.DM00088500.pdf). The pin 15 is just an example - there are more of such.How can th...
Posted on November 09, 2017 at 11:30Hello All,While build my project i got some error like below,but in application level no error . I am using the below environment1) NUCLEO L476RG2) IDE: System Workbench on STM32 3) updated AC6 plugins Error Messa...
Posted on November 08, 2017 at 08:00I am working with a DAC that requires the CS signal to be asserted/release on every command which it is 24 bits. Using normal SPI HAL functionality there is a idle/dead time between clocks for each byte being tran...
Posted on November 09, 2017 at 09:41Hi all, currently i hv facing a problem about 'no target detected' message from ST-Link utility.At the initial the physical connection is successful between STM32 microcontroller with ST-Link V2 utility, after few...
