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...

Hello Experts,I am working on i2s of stm32h743. The Manual says when the alignment is left the zeros are sifted from 0 to 7 in case of 24bit data length which is correct work but when I change the alignment right the zero does not appear on 24 to 31b...
I'm using STEVAL-MKSBOX1V1 for vibration analysis and I want to change sampling frecuency. I did it in the past with other versions of the project but now it has chan a little. I changed the ODR in the file lsm6dsox.c , but I also need to change the ...
Pwm is not continuous My clock freq 20mhz Where am i doing wrong ? void PWMparamc(uint32_t PWM_freq, uint8_t duty){ PWMparam.period = (SystemCoreClock / PWM_freq) - 1; //PWMparam.prescaler = (SystemCoreClock / TimerTickFreq ) ; temp_duty = ((...
Why there are two pending registers for interrupt? One of them is EXTI_PR and other one is Interrupt Set-pending Registers(ISPR) which is in NVIC controller registers.?What is the diffrence between them?Thanks in advance
I have some data as static class members. I use `__attribute__((__packed__))` for some classes and structs. I use type punning to convert between types that I believe have the same memory layout, but different signatures (members of different transla...
I need to preform a simple SMBus read command but I'm not understanding how to set it up. I can do a I2C read() but I can't find any examples of how to do a simple SMBus read word(). Are there any simple examples?Thanks,Richard
I have the following block of code. I am averaging 6 A/D inputs. Stream holds these 6 average values and looks fine. One at a time the loop converts each sample to ascii and appends '\n' and '\r' and then transmits them over the UART. If I use UA...
I want the maximum processing speed from the STM32H723. So I enabled ITMC and DTCM cache. The project prcesses samples from 4 ADC inputs with ADC1. ADC1 is timer triggered and set up to use DMA in circular mode to transfer data to a buffer in D2 doma...
