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...
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...
I use the following code to create critical section. Is it correct?I use the __get_PRIMASK() and __set_PRIMASK(primask_bit) from exemple codes. Why are they needed? Why disable is not sufficient?Must I enable the IRQ after or is it done in the __set_...
