We have a very weird behavior in a battery powered IoT device. We should have a very low STOP mode current draw of 1.4 uA @ 3 VCC. The problem is, as soon as we use the RTC Alarm just once and although the alarm already fired during NORMAL operation,...
Hello, I am using the NUCLE-F103RB and the STM32CubeIDE for developing and testing code. After my latest code change the program does not return form the below call of HAL_TIM_Base_Start_IT(&htim3)."TEST1" is printed to the terminal, but "TEST2" is n...
I am using the stm32f4 discovery board and writing bare-metal drivers for the embedded flash memory.I am facing a strange problem when writing to flash memory, to save you time for reading code and when the error happens, here is the status:Before Er...
Hello all,I'm using STM32F407 ADC1 with DMA enabled for sampling on 4 channels at same time, the configuration for these 4 channels are all same with DIV4 clock and 12Bit Resolution, but only 3 of them are working fine, and one channel always returns...
ST example uses 400MHz / 4 = 100MHz for SDRAM. What should the SDRAM clock be when the system is running at 480MHz? If we use 480/4 then it is 120Mhz for SDRAM, but datasheet shows max of 100MHz for SDRAM! Are we stuck running SDRAM at 60Mhz? Or run ...
Hello.I would like to use the STM32G0B0RE to write and read about 1KB of text data from an STM microcontroller to a USB memory device.When I looked for sample code to do this, I could not find any.So is there some kind of beginner's guide for writing...
Hello,We have designed a board around a STM32G0B1CB where almost all the 48 pins are used for different stuff (lots of analog inputs, communication and PWM).It is not our first design with STM32 uC, but we are facing an issue here and I would like to...
Hi ,I am trying to use 2 usart in stm32wl. But right now I am using Single uart which default PA2 and PA3 we can access through debug port, But I am trying to use through other gpios or pins through ttl But the output is not coming in terminal if I c...
I am trying to use the onboard DAC to generate a sine signal. The program runs without any problem on the Nucleo L432KC board but it would not work on our PCB with L431. As soon as the DAC is enabled with LL_DAC_Enable(DAC1, LL_DAC_CHANNEL_1); the pr...
I am using the STM32F746VET6. I am aware that assembly instructions do not have a guaranteed in execution time, however I am surprised how consistently inconsistent my inline assembly macro is behaving. I'm really hoping there is just a mistake in th...
