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 All,I'm interfacing LSM6DSR IMU with STM32H745 over I2C (1mbps). The accelerometer data looks good and consistent with pretty low noise. However, as soon as I configure the Gyro as well to turn on - the accelerometer has really wild noise.Attached...
I could get HAL_FLASH_Program to write WORDS, as soon as I moved to FLASH_TYPEPROGRAM_DOUBLEWORD the last error returned is alwasy PGA | PGS flags in the SR. PGA = alignment, PGS = sequence. I referred to every internet article I could to figure out ...
@I'm trying to add a descriptor to my BLE characteristic.#define COPY_DESC_UUID(uuid_struct) COPY_UUID_128(uuid_struct,0x00,0x00,0x29,0x02,0x00,0x00,0x10,0x00,0x80,0x00,0x00,0x80,0x5f,0x9b,0x34,0xfb) COPY_DESC_UUID(uuid.Char_UUID_128); u...
i'm using STM32F730 as uart receiver and STM32f0 as uart transmitter baud rate 9600, 8 bit data representation. i'm using DMA with interrupt for the communication. i'm using HAL for programming on IAR workbench. The transmitter is continuously transm...
I'm trying to inject a simple wrapper around my timer interrput handler written in C - primarily for debug purposes to simplify debugging the state of registers and stack before the C code gets in and messes up the stack and state pushing all the jun...
Hi all,I am using Nucleo-L552 Evaluation board running , CMSIS_RTOSV2 (FreeRTOS), firmware STM32Cube FW_L5 V1.3.0. Debugging via built-in ST-Link. I have a Hard fault on HAL_GetTick() when running UART transmit on one of the threads. It debugs fine w...
Sir,I am using the STM32L432 for my project.How to get the PVD state ?I want to know the power voltage that is above the level or under the level.Thanks.void HAL_PWR_PVDCallback(void) { if ( __HAL_PWR_PVD_EXTI_GET_FLAG() ) { // TODO: get ...
I am not too familiar with embedded systems and just started learning about them. I have some parameters that lives in their own flash sector (16KB). They are stored as one long string ("PARAM1=X\r\nPARAM2=Y\r\n...." and so on). One of the parameters...
Hi everyone, I'm trying to use Input Capture with 1 Timer by using both edges option as external. I'm new at this microcontroller and I could not understand how to make it correctly with HAL library. Can anyone help me how to do?
Hi,I am using STM32H7's Timer 2 peripheral to generate a clock frequency ranging from 10Hz to 1MHz. To reconfigure the PWM to attain certain frequency, the PSC, ARR and CCR1 registers are modified.The sequence for modification is as follows: PWM_Star...
