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...
Hello I am using a STM32L476,I am having issues with the power consumption, Every time it resets, the power consumption is different as in +-500 uA but I have seen as much as +-1.0 mA.I am using the MSI at 48 Mhz. After initializing the clocks, I in...
I am new on STM32.I have one switch that i define it's external interrupt. i want to put my mcu in sleep mode and at another interrupt i want my mcu wake up. i don't have any idea how to write routine for wake up and sleep mode API when interrupt oc...
Hi,I'm trying to use my STM32F7 Discovery Kit to just fire a HTTPS-Get Request up to my Server.Im using mbedtls and some http(s)-library I found on Github. But that doesn't feel right, is there any official Guide, Library or even a sample project for...
Hello, I am trying to create an external loader for N25Q128A QSPI. I'm currently developing on STM32F469I-DISCO. My loader doesn't work once loaded into STM32 ST-LINK utility (nor in CUBE programmer). If I modify my project adding a main file with a ...
The datasheet states:>ADDR: Address sent (master mode)/matched (slave mode) This bit is cleared by software reading SR1 register followed reading SR2.In case a single byte has to be received, the Acknowledge disable is made during EV6 (before ADDR fl...
in some cases that we encountered, 2 types of failure occur. 1- when powering up, ALL sectors of flash, are Erased. we guess ESD makes all sectors erased. with additional protection in power circuit, this problem solved.2- after powering up, we reali...
Hi,I had to port to STM32L151ZE from STM32L151ZD because of a RAM limitation. The code seems to work as it is, however I am facing issues in SPI communication when the SEGGER J-Link debugger is kept connected to the board. I tried probing the clock ...
Hai , my name is Dattu i am working on a project which involves measurement of current using ADC on STM32f407VG to achieve this i am using a 30A ACS712 sensor i have interfaced the sensor but when i am running the program i am getting a const...
We have a problem like "2.1.11 Unexpected system reset when waking up from Stop mode withregulator in low-power mode", with chip revision Z, but with revision X too. This error occurs sometimes, even with workaround. Ist this topic completely solved...
Hello,I am struggling with integration of filesystem on external nor.I've been trying both littlefs, and spiffs. Both, with no success yet.Is there any suggestion from ST for filesystem example on external nor flash ?Thank you!ranran
