Hi,I am using STM32H753 controller in my design, I am measuring the current consumption in vbat mode with the battery and found it to be around 1uA. The RTC Configuration was RTC_Alarm_A enabled.But disable the Alarm_A in the RTC configuration, the c...
RM0440 table 7, even in rev. 2, does not describe the flash layout of devices with less than 512 kB flash in dual bank mode.Is there a gap between the two banks is this case or not? The textual description doesn't even mention devices with less than ...
When UART works in RS485+DMA mode, after initial, HAL_UART_Receive_DMA/IT enalbe manually, I fould systick woundn't work any more.Who meets this issues or has any advice, comment is welcomed, thanks in advance.UART configuration in MXCube
Hi everyone, i'm using uP STM32F103C8T6 processor and GPS module NEO M6Q with standard uart configuration on 9600 baud-rate .I enable global UART2 interrupt to receive data from GPS module on every second. But for some reasons, interrupt starts skip...
Hello,I'm trying to use an STM32F4 Discovery, specifically the LIS3DSH accelerometer onboard and I'm experiencing some behaviour relating to the external interrupt of the LIS3DSH that I'm confused by.When downloading the code to the board using Keil ...
Hello, I am using STM32L021F4 on a custom board and I am attempting to flash firmware using the FLASHER-STM32 software via the internal bootloader and a FT232RL USB/UART serial bridge. I can connect to the MCU and the flash loader says the MCU is rea...
I am trying to use STPM33.I am designing a circuit with reference to the reference circuit.The circuit I'm looking at is the 'EVALSTPM33' circuit from the STPM33 kit.I have two questions.1. Many circuits are falling to ground. What is the difference ...
Using a STM32F413 and ADC HAL drivers.After a successfully completed single conversion initiated by HAL_ADC_Start_DMA() one apparently needs to call HAL_ADC_Stop_DMA() in order for next HAL_ADC_Start_DMA() to actually start a new transfer. There are ...
In the while loop I have this:HAL_ADC_PollForConversion(&hadc1, 1000); adcValue = HAL_ADC_GetValue(&hadc1);The ADC works okay until I execute this line, which is inside a function:HAL_GPIO_WritePin(GPIOB, GPIO_PIN_7, GPIO_PIN_SET); HAL_Delay(3000); c...
