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 have a STM32H745 MCU, which has both M7 core and M4 core. I created a project in CubeIDE, and the code that is automatically generated expects both processors to be active.Indeed, in the code of the main. of core M7, wait for core M4 to boot be...
Hello.I'm trying to make an I3C Master device using the NUCLEO-H503 board.I am trying to implement GPIO by directly controlling, without using HAL Library.However, I3C port uses both Open Drain and Push pull,Is it possible to implement this function ...
Behaviour of WWDG on STM32L071KZUx.We are trying to read and write 256bytes from the Slave. In a specific case the Slave needs delay of 120ms to process the data when we add 120ms of delay in the MCU, the void HAL_WWDG_EarlyWakeupCallback(WWDG_Handle...
I just want to know about using SPI CS alternate function or a simple GPIO output. In my design I just have a pin with no SPI CS alternate function available, so could I use it as a simple GPIO output?
Hi AllWe are testing the STM32U585 Smart Card mode with clock and trying to connect with external SAM module. We are able to get the USART-ISO7816 frame format from the controller but we are unable to capture the ATR value from the module in a correc...
I've been trying to get TIM2 PWM (or even OC) to produce an output. When looking at the registers, using openocd w telnet, I find that setting 0x40000000 (the CR1 register) with 0x81 also sets the 0x4000004C (the DMAR) register. The reverse is the sa...
I'm having trouble getting TIM2 PWM to work so I've been studying the RM closely. The following conflict came to light.The RM shows TIMx_ARR and TIMx_CNT as 16b, but TIMx_CCR1,2,3,4 as 32b. The text (section 17.2) says TIM2 & TIM5 are 32b. Some debug...
The goal: Debug the NUCLEO-H743ZI2 with Tracealyzer.To do it I have to connect the board with my computer via jlink. I found the tool STLinkReflash, that can emulates the jlink in the stlink. The problem I found is that it does not work for the stlin...
I am attempting to use a rotary encoder (Bourns PEC11R-4215F-S0024) with an STM32F091 Nucleo board. I would like to have it count a consist number of "counts" for every "click" of the encoder.Hardware Setup: Pin A is connected to PA0, Pin B is connec...
