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 use OCTOSPI1 and OCTOSPI2 in multiplexed mode to interface with two S27KL0641 ram in Memory Mapped mode.Those Rams are used for LTDC Frame Buffer and for other application data (structure, data ...).I started from the STM32Cube_FW_H7_V1.9.0\Dri...
Hello,I miss a specification for timer ETR input frequency. The fext specification is only for CH1-x and with ftimxclk/2 is show that these inputs are sampled. Is the ETR input also sampled?
I have been trying to create a asynchronous serial UART communication on GPIOA pin 9 and pin 8pin9- is RxPin8- is Txin order to sample the message at the right time I have create a dealy function using the DWT mechanism, the idea is to wait 1.5*(1/b...
Hi,As I understand, the STM32F413 MCU doesn't have dual-bank architecture, but I'm still able to perform read-while-write (RWW) operations without causing the CPU to stall.I have a little experience of working with the chips that don't have an intern...
Hello guys.I try to catch the IRQ of arbitration lost and error code in LEC in FDCAN in DAR (disabled auto retransmission) mode.I have 3 devices in CAN network: STM32F207 - 2 pcs STM32H745Q (dev board) + external phy.All devices works good. They ...
Hello , ı read RM0433 ,I could not understand the process in the image below(page 2198)
I am using a NUCLEO-L476RG development board, I am learning to write GPIO drivers for STM32 family I am implementing a simple logic in which I need to turn on an LED when a push button is pressed.I have a strange issue: The Bread board LED turns ON w...
Hi I am trying to optimise my gait generation code for my robot. I use a lot of float operations . I want to use FPU to accelerate computing. As an experiment I am using the following taskTickType_t start = xTaskGetTickCount(); while( i<100000000) ...
Hello,The M48T12 memory outputs a test signal at 512Hz, with a deviation of 0.001Hz.I tried to read this deviation using a 24MHz sampling logic analyzer, but there was still a fluctuation in the reading of the thousandths of a Hz.I think maybe a 100M...
