Hi,I’m using an STM32U385 (Cortex-M33) and trying to enable the Micro Trace Buffer (MTB) using ARM’s MTB-M33 register addresses (0xE0043000 base).No matter what I try, the EN bit in MTB_MASTER never sets.Does the STM32U385 have the MTB component?Than...
Hi, I’m working on an STM32L431CBT6 project where I enter STOP2 mode and measure ~1 µA current, which is great. However, I need to use PA0 as a GPIO input to wake up the MCU from STOP2. When I configure PA0 as an input (no pull, or pull-up/down), my ...
Hello, I hope this message finds you well. I am currently testing two MT25QL512ABB devices in dual mode using the STMH747I, with the same driver for the MT25QL512ABB. After performing write/read verification and rebooting, I encounter issues during s...
STM32U575RGT6 + LIS2MDLTR三轴磁场传感器，通过IIC配置传感器寄存器模式，0x20、0xFE;0x21、0x00;0x22、0x00;0x23、0x0C;0x24,0x40。但是通过测试，Debug出来的点数，Z轴数据不变
I am working with STM32H745I-Discovery board. I trying to do Data transfer through SPI with DMA. But unable to transfer the data. Could any help me with example code for STM32H745I-Disco board.
I made pcb with stm32l011d3, but st-link doesn't detect mcu.Detect other commercial pcb with st-link, so st-link has no problem.I know that boot0 in the current dataset is not connected to gnd. It is not recognized even if I connect it to gnd right a...
Hi For some reason, an interrupt isn't being triggered when I connect the USB to my stm32 board, and the reason is baffling to me. I have attached the relevant excerpt of my code static inline void core_initialisation(void) //from page 3403 { USB_O...
I am working with an STM32C092CCT6 (STM32C0 series) and I need help with reading and writing variables into Flash memory.I want to store a few configuration values (like integers or structures) that should persist after reset or power cycle.From what...
I'm using the STM32F103C8T6, and trying to blink my LED via the interrupt handler of a DMA with this code#include <stdint.h> // STM32F103C8 is a medium density device, hence we use the xB header #include <stm32f103xb.h> #if !defined(__SOFT_FP__) && ...
Some of the STM32 CPUs have a USART with a Timeout timer which is good for modbus applications.Is there any overview available which CPU devices have this specific periperal implemented?In the Datasheet this function is called RTOIE, or RTOR.
