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 20, 2017 at 20:16dear ST Community,i am trying to talk to a smart battery through SMBus as bellow:to initialize: an I2C of the STM32F407 as SMBus.to transmit battery address ( slave )to acknowledge from itbut the command doesn't b...
Posted on November 20, 2017 at 04:30Can you reset a counter from another timer? I'm using TIM2 as a PWM input and in the callback() I'd like to reset the counter for TIM22 to stop it from triggering its interrupt. Is this possible?This is what I'v...
Posted on November 20, 2017 at 17:26Hi, I wonder why the STM32H7 distribuitors prices are so much higher than ST prices for 10K units compared to others STM32 devices. Ex: STM32L4R7VIT6 ST price for 10K = U$7.80 and Distribuitors minimum pr...
Posted on November 20, 2017 at 13:41I'm using STM32F302 Nucleo board and I'm trying to configure TIM1 in such a way that it will output a 12 us long pulse on its output.I've configured TIM1, GPIO port C with its appropriate alternate functions as we...
Posted on August 24, 2017 at 23:47More (Cube, both L4 and F4).Why does Cube write to DAINT, once it's read only?And why does it handle GINTSTS.MMIS interrupt, once it was never enabled?JW
Posted on March 20, 2015 at 14:12 I'm having issues making the RTC work as expected. This is the code which is called periodically: RTC_TimeTypeDef currentTime; HAL_RTC_GetTime(&hrtc, ¤tTime, FORMAT_BIN); char uartMsg[32...
Posted on November 10, 2017 at 15:29Hello,e.g. pm0253, chapter 2.4.4 Vector table talks about a possible value of 0x80 for the vector table offset register. However chapter 4.3.4 'Vector Table Offset register' clearly requires an alignment of 0x200....
Posted on November 13, 2017 at 05:01Hi,We are planning on using the STM32H753 in our design. We currently have the STM32H743 eval board with us and we have the following query regarding the sd card schematic on the user manual 'UM2198'.Qn.: The sd ...
Posted on November 20, 2017 at 03:04 In the flash memory as shown in the following code, the str1 and str2 values are divided into 4 bytes I want to write down. I have an error like the image I captured .; When I have an event, I write it to Fla...
Posted on November 20, 2017 at 07:45I am working on STM32F765BIT MCU with our custom board . In our board NAND flash is connected to Bank3 (0x80000000 - 0x8FFFFFFF). I configured using STM cube and just tried to read device ID but MCU is getting loc...
