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...
Hi everybody,I am using STM32F042G6 MCU for an automotive project and since It doesn't have mush FLASH (32kB) I am trying to reduce code size as much as possible.Lookign at the linker file generated by STM32CubeMX, I see that instructions are aligned...
The STM32F429 processor operates at 180MHz, with a clock cycle of 5.56ns. Can we generate pulses with a width granularity of 5.56ns using only ARM instruction delays?For example: 5.56ns, 11.12ns, 16.68ns, 22.24ns?In practice, I have encountered diffi...
Is there a way to reset the counter and the prescaler via a hard event or something when an input capture happens?I use timer 1 to have a hall interface and to drive timer 8. But there are some fluctuations, because the interrupt (where i reset count...
I'm using STM32F407 as a USB host. I have multiple devices in which we are using CH340E as the USB to serial communication. The problem is if that device somehow turns off and CH340E loses its power. The USB Host can not transmit data to the other de...
hi,The datasheet says "In this mode, the TCR flag is set when the number of bytes programmed in NBYTES is transferred"Does this mean that the flag will be set when the data is transferred from TXDR to shift register, Or, the flag will be only set if ...
Hi,I've been using stand-alone RTCs that clearly indicate through a specific bit whether the date is correct or may have been corrupted by undervoltage.I cannot find any clear indication of a similar feature for the RTC integrated in the STM32F446 (u...
Can we use the Internal ADC Vref channel and External analog input channel simultaneously in STM32L053R8 and get data using DMA.?
Hi, I'm using an STM32L053R6Tx chipI've implemented at TMR2_interrupt hander it gets triggered on ARR overflow and CC1FI'm using the interrupt to trigger a GPIO output to work like a PWM the- GPIO is high when CNT is less than CCR1- GPIO is low when ...
I'm new to using the Nucleo environment I am not seeing any activity on the PB10 and PB11 when using the SMBUS_TwoBoards_ComIT_Master example, when looking at those pins on a scope. I only have one board currently. - Board: NUCLEO-U575ZI-Q (embeds...
Hello,I've been doing a small project lately and ran into a problem in one part. I have two STM32 microcontrollers and I want to communicate both of them with eachother over UART. One of them is designed to send a fixed array of 6 charactersuint8_t k...
