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 03, 2013 at 18:38Hi all, on my discovery STM32F4 the LD8 is blinking and I don't know why. There is nothing connected to 3V nor 5V pins but some 6 ADC inputs 5 PWM outputs, one UART and one I2C data connections. All devices are powere...
Posted on June 02, 2013 at 21:41I am using the STM32f4 series. My goal to drive an external parallel loaded DAC using data from the internal SRAM. So, I need to update the data on a GPIO port and then toggle a pin connected to the load control signa...
Posted on June 03, 2013 at 15:35Hi,I want to use MCO1 to control an external device using the LSE RTC crystal 32Khz. Does any body know what is the behaviour of MCO1 in stopped or standby mode for STM32F2 device?Thanks. #mco-low-power
Posted on June 03, 2013 at 15:06Hello I want to use sqrt (square root) function to calculate sqrt (x^2 + y^2) but i haven't math.h in my root this is the error undefined reference to `sqrt' collect2: ld returned 1 exit status how can i fix it ple...
Posted on June 03, 2013 at 10:42Hello, I'm currently programmed a STM32F4 Discovery with the IDE Atollic. In my program, I get two fonction, the first in the file ''stm32f4xx_it.c'' and the second in the file main.c and i want to known if i can tran...
Posted on June 03, 2013 at 13:36Anyone know the fastest possible frequency that any GPIO pin state can be toggled?
Posted on June 02, 2013 at 15:52Hi community, for a few days i try to use the SPI1 on the F4Discovery board. I use the PA5-PA7 pins on AF5. But after my init the code does nothing? What is wrong in my init function? #define Open_SPI_MISO_PIN ...
Posted on June 01, 2013 at 17:05I have implemented the code of this linkhttp://www.st.com/web/en/catalog/tools/FM116/SC959/SS1532/PF252419 that allows sending and receiving a file from a flash drive via the usb stm .. but the problem is that an indi...
Posted on June 03, 2013 at 01:29I'm trying to output vga signal using timer1 ch1 for hsync, ch2 for interrupt (horizontal backporch) and timer3 ch2 for vsync and ch3 for interrupt (vertical backporch). I'm using E0-E2 pins for direct output and I ca...
