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...
Is it possible to set an output to "1" or "0" with an instruction of one cycle?
Hello, ST expertFrom the picture below, it showes that 5V tolerent GPIO connect to VDD_FT through a protection diode. But what is detailed difference between VDD_FT and VDD? BRYang
Hello. In a project with stm32g030 (071) I use two different timers to generate two PWM signals. The triggering of timers and PWM signals is out of phase by 180 degrees. Can I use one DMA buffer to load data into CCMR registers of two different timer...
Hello,I have a problem with pins PC2_C and PC3_C on STM32H7. We have custom board based on this MCU and we want to interface SD card via SPI. We are using these pins: PA9 as SCK, PA0 as CS, PC2_C and PC3_C as MISO and MOSI respectively. I can not ini...
Is it possible to calculate how many clock ticks a function or select block of code will use up?
I'm using Atollic TrueStudio 9.3.0. I know it's not the latest, but now is not the time to change anything.I've been debugging my custom boards no problem, for years, including setting at stopping at breakpoints. All of a sudden this morning, the d...
Hi everyone!I'm using a custom board with an stm32l051 and an lsm6ds3(and two 4.7kohm pull-ups). I am setuping the I2C1 (pins PB7 SDA and PB8 SCL). then I do the IMU setup in which I write some values to control registers on the IMU. then I read the ...
In RM0440, it states that "Generation of a single interrupt request for the DMA1 controller," however looking at the exception vectors indicates that there is a separate interrupt vector for each channel for both DMA 1 and 2. Also the stm32cube libra...
Hi all,I am using STM32F303CB microcontroller, connected with a I2C slave which has no CLK stretching support. The I2C bus lines are pulled high with 4k75 ohms resistors and the lines have a serial resistor of 50 ohms (approx.). The schematic looks l...
We have got quite complicated repositories structure and excluding everything manually for new projects takes too much time.
