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...
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...
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...
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, ...
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 ...
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...
Hi community,We are generating a static library for our Cortex-M7 (STM32H743VI), using the following command:arm-none-eabi-ar rcs libtf.a $(OBJS)How to generate the debug symbols ? (so we can debug the library files while using it in the main applica...
