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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
When I try to run a project in Release I get this message:No source available for "Reset_Handler() at 0x80007c4"What does this mean ?I do not see it in debug, and BTW I did set the mode to Release...
Hi, i'm using stm32f429 to develop i2c communication, the mcu cannot generate START signal after running a few minutes but the SDA and SCL all high, I add the CR1 register to watch and find the CR1 cannot be modified after calling the bellowing: br...
Hello everyone,stm32l series MCU going in STOP mode and dwt has been enabled before, RTC wake it up with 20 seconds. Callback is called with 20 seconds and always dw_val increments with 2 sec. What is going on the backgorund. Normally as much as I go...
We're trying to read from the ADC from 2 channels by using EOC interrupts.When we read the values seems like the channels are wired together.As such we can't distinguish between whether they come from one channel or the other. Here is the code that w...
I need my code called when something connects to the HAL UART.I have a simple mini-debug that just prints something to the UART and I see it on a console connected to the STM debug COM port. I noticed that the HAL_UART_Transmit() always returns HAL_O...
Hi All.I am building a function using ADC with DMA.what i did in the while loop is just toggling a GPIO Pin.but it seems that the while loop will be interrupted when ADC is triggered.does it means that when ADC is triggered, while loop will be stoppe...
Hi, I have several issues trying to run ADC in continous conversion mode with DMA circular buffer. The fact is that is starts to work normally but after a random time adc raise the overrun flag and adc and dma stop running. I´ve tried multiple clock ...
Hello, I'm working with an STM32G05, on a very simple custom board. I expose both USARTs to external headers.USART1 seems to be operating fine - in that I can send/receive data.However, USART2 is not.When I inspected the TX line I discovered it was l...
I want to use FFT functionality on stm32f4xx mcu, so where can I find some guide document about this? Thanks!
