STM32F4 Discovery - External interrupt requires reset button press to function
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 ...
STM32L0 can't flash with FLASHER-STM32
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...
STPM33 reference circuit. I did not understand.
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 ...
Is there a HAL_ADC_Stop_DMA() alternative to be able to start second transfer using HAL_ADC_Start_DMA() for single conversion?
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 ...
Resolved! ADC gets stuck after doing a HAL_Delay
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...
Has anyone successfully ran an STM32F4xx CANBUS at 500K baud ?
We are using the STM32F446 at 180 MHz and one of my engineers says he can't quite get the CAN peripheral to run at 500K (reliably?) with the available clocking system.Anybody know any tricks to make this work ?This is partly what he said....."I don...
Resolved! Automatically set DBGMCU when debugging starts.
I am debugging my software on STM32L452CCU6 and it is mostly in sleep mode. By default, this disables clocks to the debug port, and the debugger (using STMCube) prints out the message "Target is not responding, retrying...". After a couple of times, ...
STM32L4R5: RTC slow when using SHUTDOWN or STANDBY mode with periodic wakeup
Hello,while testing our new PCB we discovered, that the RTC does not keep time correctly. I therefore measured the 32kHz clock driven by an external crystal, therefore I enabled PA2 for LSCO output: Interestingly, the signal was fine - stable and no ...
Project/Application with drivers updated
Good morning,I have an application based on the STM32L4 device. When I started working on this application (I use Keil) I used Cube in order to setup the device according to my application. Please, look at attached picture where drivers folder in Kei...
