Is uint16_t and uint32_t interrupt safe in Cortex M architecture?
I am working on some embedded stuff and I had multiple interrupts possibly working on same data and so I was wondering if uint16_t and uint32_t data types are interrupt safe.If interrupt is working a uint16/32_t data and is halfway interrupted by ano...
STM32 I2C multi-device connection
Hello to everyone, I am a newbie on STM MCUs. I need to communicate 6 slaves and 1 master device. But I could not figure out. The master device has been selected Arduino mega due to some specifications. Slaves are responsible to drive motors, Arduino...
Sensortile standby high consumption
I am working on a project using the sensortile. When the MCU is not in use, it enters a standby mode. I measured a current of 4.5 mA in standby mode. What could be the cause of such a high consumption in standby mode?
Resolved! Can't download the software: there is no "Get Software" button
hello，I want to download software from ST Website ,but there is not button to supply.thank you.
Losses the bytes of data in LPUART IRQ HANDLER?
I have configured LPUART with 9600 baud rate and enable receiver interrupt with MCU 65Khz low power mode and my uart handler likevoid LPUART1_IRQHandler(void){ uint32_t isrflags = READ_REG(hlpuart1.Instance->ISR); uint32_t cr1its = READ_REG(hlpuar...
Uart timeout?
Hi,I am using LPUART for sending data to the GSM. I wrote own uart transmit driver without timeout, like void LPUART1_Send_Data(uint8_t *string){ while(*string) { if((LPUART1->ISR & USART_ISR_TC)==USART_ISR_TC) { LPUART1->TDR=*string; ...
HAL_SRAM_Read_DMA() assumes 8-bits word ?
Hello,When using SRAM without DMA I find several group of APIs for read/write, depending on bus width:HAL_SRAM_Write_8b HAL_SRAM_Write_16b HAL_SRAM_Write_32band also read APIs of course.But for DMA there is only: HAL_SRAM_Read_DMAHAL_SRAM_Read_DMAIs ...
FDCAN (Classic, Normal) STM32H753 STM32CubeMX HAL
I am new to FDCAN on STM32H7.Using STM32H753VIT6, STM32CubeMX , and HAL, I configured both FDCAN1 (master) and FDCAN2 (slave) at 250 kbps, and all seems to work fine.To check it, I used a MicroChip CAN Bus Analyzer Tool (BTW a very limited and buggy ...
STM32L4 ADC Configuration to read internal temperature sensor's data.
Hello there,I am working on STM32L4's ADC and wants to measure internal temperature sensor's readings.But somehow, I am facing some issues here.1. Calculated Temperature is incorrect:I used below equation, provided in reference manual RM0393's 16.4....
