STM32L412 how can I individually turn off EXTI flags without HAL?
Im using external interrupts on an STM32L412. I want the interrupt to run as fast as possible so I'm not using the HAL to turn off the request, rather I am writing directly to EXTI -> PR1, which needs to be written high to turn off the interrupt, but...
STM32G071 Temperature Sensor stabilization time
HiIn CubeIDE the temperature sensor stabilization time for my STM32G071 is defined by: stm32g0xx_ll_adc.h#define LL_ADC_DELAY_TEMPSENSOR_STAB_US ( 10UL)But in the Datasheet I see at least 15µs max for Tstart(ts_buf) and for Tstart itself its alrea...
interrupt problem
Hi thereI am using a STM32F103C8T6. I defined this pins as External Interrupt:PB4 - GPIO_MODE_IT_RISINGPC13-GPIO_MODE_IT_RISING_FALLINGPC14-GPIO_MODE_IT_RISING_FALLINGPC15-GPIO_MODE_IT_RISING_FALLINGthe problem is that every time I SET/RESET PB4, it ...
STM32H745 Cortex M7 UART Transmit and Receive with DMA Problem
We have tested UART3 with both Polling and Interrupt and working fine. But now we wanted to receive stream of 25 bytes each line continuously with DMA enable on UART RX.But We are unable to Receive any data with UART DMA. I dont find any example for ...
what are default memory attributes in ARMv7-M architecture?
Flowing pictures have no hints to "Bufferable" attribute. Also in Cache column, some region have WB attributes which is just about caching capability; but we know that ARMv7-M architecture didn't consider any cache or cache controller inside the proc...
What are default memory attributes for stm32F4 or other stm32 devices?
Hello;I want implement MPU unit in stm32F4. I have read ST documents about stm32F4xx, but did not find any thing about default attributes (write and read policies) for memory regions before enabling MPU. It means that: what memory attributes dose stm...
Resolved! Error with pointer to a typedef struct
Hello, I have a problem with a typedef struct.I made a typedef struct :typedef struct BMP280_HandleTypeDef{ uint16_t dig_T1; int16_t dig_T2; int16_t dig_T3;} BMP280_HandleTypeDef ;In my function I declare the instance of it :void myfunction{BMP280...
