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...
Before starting the blinking program, when I plugged in my PC USB to micro the user LED's (1-3) could be toggled when I hit the blue push button, now they can't.Within Kiel, I started a new project LED blink. I found my MCU (as seen in the image), th...
I received my Discovery board a week ago and still I can't load any examples. I can run a new project (I followed a tutorial) without problems, but when I try to import examples such as the 'audio playback and record' I can't build the project, debug...
Hello,In the datasheet for the STM32F423 , I see at the table 18 "Features depending on Power Supply range". I want to understand what will be the performance of the MCU if I power it with 1.8 V. I don't clearly understand the table. At the column ...
Hello,I am using the XIP functionalities over QSPI on the EvalBoard STM32F7308-DK. I got the launcher working without problems (jump to 0x90000000U, which is the QSPI base address). I also got a basic demo (toggle led) working from the external QSPI....
I tried to sort through the manual. When I choose external clock do i actually connect anything to the PH0 and PH1 pins and what kind of oscillator.I see that there is already what looks like 8 MHz crystal is this one I am connecting when using exter...
Hello everybody,I wanted to measure the duty cycle (tone) of a PWM signal with input capture mode. Unfortunately, it works only almost up to 65% of the duty cycle(Ton). otherwise will the T_off measured instead of Ton. does anyone have an idea what c...
Hello all,In my Project i m using stm32l031k6t6 microcontroller interfaced with GSM and GPS module and external FLASH memory.For that , first controller read coordinates information from GSM and GPS module and store it into flash memory for record. a...
I will need to handle dynamic memory using malloc and free. Looking on FreeRTOS documentation, I found pvPortMalloc(size) and vPortFree(ptr) , pvPortMalloc(size) works fine. When try to release memory using vPortFree(ptr) inside a Thread, the code ...
Is there a way to have spi just send an abnormal number of clock cycles as opposed to just 8 cycles at a time? Is bit banging the only way? Can the LL library be configured or coded to do such a thing?
Hi I'm using STM32F7 series microcontroller. Is it possible to send 9 bit data using SPI? the reason is i have to send 8 bit data along with command bit (ie 9th bit). I have seen some option in datasheet like we can chose the data length between 4...
