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...
Dear Members,I got a wrong data on I2C 2 for LCD, the first time it was ok, after a while it becomes like in the photo, what do you think the cause of it ?I have put a pull up resistor for it 10K, and the speed is 100KHz,I2C1 for Accelerometer and te...
HiTimekeeping in my application is pretty standard: 32 bit unsigned integers which store milliseconds since boot, overflowing every 49 days.To reduce power consumption, i need a way to wake up from stop mode at a set time in ms. But my device has nei...
Is there a document outlining how to power and test the crystal oscillator from ST? STM32F405
Hi, there, I am not sure this is the right place to ask if it's concerning IDE.Just got my new STM32H747 Discovery kit, running CubeMX examples,All running well, except for debugging:(I am using MDK Keil (V5.27 / V5.28) and on-board STLink V3)I found...
Hi, Im senior engineer using stm32, maybe, not newbee.I know that Higher interrupt priority can occur when mcu still process lower interrupt.Higher interrupt , i mean, lower priority value in nvic register.but just now, I found gpio interrupt can dis...
I do not understand the difference between the different sampling rates (cycles3 - cycle480). I know it is related to the time given for the ADC capacitor. I also realise that more time should mean more stable reading. I ran some quick tests and I f...
I have a Value Line Discovery board - STM32F100RB and three of the outputs are connected to a 3v3 converter to get a 5v output. I have tried another controller board with 3v3 outputs to drive the convertor board and I get a clean signal. (Either 0 or...
I am currently working on switching my Keil workspaces to Atollic TrueSTUDIO.I realized that my calculation cycle time in TrueSTUDIO is much longer than old workspace that is implemented in Keil.I was using __sqrtf() function instead of sqrtf() funct...
I'm a bit lost by this one. I can write to the flash but cannot erase a sector. I can erase sectors with the ST-Link Utility. The result codes at every step indicate success, but the flash is not actually erased. I am using the Standard Peripheral Li...
