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 October 14, 2013 at 15:49I'm new to STM32 so please help Is that possible to trigger SPI+DMA transfer from GPIO? I have RM0038 document and on ''DMA1 request mapping'' (page 213) diagram there are no GPIO pins. I assume that SPIx_RX and S...
Posted on October 08, 2013 at 13:49Hello,I work with a STm32F417 FreeRTOS + lwip 1.4.0 + 7.1.1.I get crash HardFault_Handler. Sometimes after a few minutes, sometimes after a few hours.There is a screenshot in attachment.I can see that it comes from...
Posted on October 12, 2013 at 22:03Hello,I am trying to apply CRC to an 8-bit array for creating checksum in order to use in transfer. Since CRC of STM32F4 uses registers as 32-bit, I need to do something tricky.For instance, a 8-bit buffer with 42 ...
Posted on October 11, 2013 at 16:46For example i want to use TIM9_CC2 event trigger. I don't understand when does this event happens & triggers the ADC to start sampling. I thought one controls it with TIM9->CCR2 value, but thought wrong - unless i...
