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, i want to store some bytes ( 4 Bytes) of data in MCU flash registers in program run time . In flash user locations are available or not. If available how can i assign the bytes to flash locations in run time.
The new STM32G474RE has an ADC that can run up to 4MSPS.I'm doing a project where I need to do the sampling in 1MSPS. But the maximum sample rate achieved was 300kSPS. When I set timer 1 for the ADC trigger to 500kSPS the "while" loop simply locks. S...
I need clarification on part 2.14.2 of Errata - Wrong data may be read from Message RAM by the CPU when using two FDCANs. As a workaround, it's stated there that "To avoid concurrent read accesses between the CPU and FDCANs, use only one FDCAN at a t...
Hello, i have some trouble with my L073z-eval board. I try to use RTC with LSE and found it very inaccurate. I checked the frequency using TIM21 (capture-compare mode with remapped LSE as input) and see very instabbility value - some times value goes...
This seems very confusing. In the manual the pin is marked ANA which it annotates as Analog-only input, and yet it has a bunch of special functions that are digital in nature (e.g. SPI_MISO, FMC_SDNE0) and both input and output. CubeMX allows me to s...
I am programming the uC via UART that is connected via a Transceiver. The transceiver has an DE (Driver Enable) pin which is active high. Unfortunately, it has a pull down instead of pull-up in a design, therefor the uC can hear but can't talk back. ...
RM0316 says it's TIM5:but there's no TIM5 in the 'F3 (except 'F373, to which RM0316 does not apply).ST please clarify.JWPS. Textual search finds TIM5 also in description of the TIMx_CCRx registers, obviously copy-paste relics.
Dear sirs,I'm trying to use STM32F469I-DISCO USART6 (PG9 as RxD and PG14 as TxD).The transfer is succeed (I checked using a logic analyzer). But when set the transfer data to the DR register, 0x7F is appeared the DR register and RXNE bit is set, with...
which one is more advantageous to work with as a Student and developer.
