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 June 07, 2013 at 17:32Following my last post on the subject of flash memory erase vs watchdog I have another concern.Reading the spec I believe that I may be able to change the prescaler+reload of my watchdog just for the time that the fla...
Posted on August 20, 2013 at 16:57Hello,I am working for 6 months with the Timer 2 of a STM32L15x.I use the channel 2 to capture the timer value; The pin used is PB3.My application is working fine.Now, for an hardware problematic, I need to use the ...
Posted on August 21, 2013 at 01:04I can't get USB_OTG_FS communication to work on the STM3240G-EVAL board. USB_OTG_HS works with no problem. I tried disabling HS using JP31, but ST's example application still can't reach the USB_OTG_FS.I thought thi...
Posted on August 20, 2013 at 17:12 Hello, I am trying to access GPIOB registers on STM32F373 using bit banding memory access. Per the documentation, all the peripheral registers are mapped to bid-band memory locations. While it is easy to ...
Posted on August 20, 2013 at 17:35 Hi, I'm trying to implement ADC multichannel scan (single sampling) with DMA on STM32L152 but there's a problem with conversions start. First SW conversion start takes the samples but following start com...
Posted on August 20, 2013 at 20:03Hello, I was writting a driver for SPI transfer using double DMA ... to test it I wrote a few lines of code that prepared a buffer (locally), and sent it over SPI. The result was the first 4 bytes were ok then the d...
