I'm using stm32f105VC. I have enabled the WWDG clock in RCC_APB1. I'm writing to WWDG registers.The problem is that WWDG doesn't start. The printed value is 0x7F - always the same. I've checked also registers by Truestudio - both CFR and CR always ha...
Dear fellow STM32 users,I've Managed to get the current consumption on my l100C discovery board down to 3.8µA with only the RTC running on the LSI. Steps that I've performed so far:Removed r27 on the Discovery Board (connected to BOOT0 pin - it was d...
Hi,The STM32G0 seems like a nice lineup for Mainstream MCUs.For my product the specs would fit quite nicely, but I would need CAN bus support.In several Presentations it is mentioned that some will support CAN FD (up to 2 instances), but I have not ...
I would like to use four TIM1_BKIN pins with timer 1 such that if any one of the four break inputs is active, the timer outputs are disabled. I.e. if multiple pins are configured to be TIM1_BKIN, are all of the inputs OR'd together? This would elimin...
What are the changes required on STM32F769I-EVAL evaluation board to use UlinkPro debugger?
I'm testing stm32f302 ADC capture with DMA transfer, but get some strange issues.I set the ADC1 to capture single channel AIN2(PA1) in continuous and DMA mode at 72MHz and 1.5 sample cycles. Set the DAC1 output a fixed voltage of 2048 with VDDA = 3.3...
Hello, I will use STM32L4R9AI in a battery powered design with PSRAM that powered at 1.8v and flash memory that can work at wider voltage range (in addition to DSI display, RTC, ADC, DAC, USB, I2C) so my power scheme is as following:MCU:VDD : 1.8vVDD...

Hi everyone,I have recently starting becoming familiar with the M-Cortex structure and instruction set ( I was raised on Atmel MCUs in school and this is my first time working with M-Cortex and .thumb instructions) I am trying to learn as much as I c...
Hi, I'm using an audiocodec with a STM32F4011 through I2S interface. I configure I2S to transmit/receive in DMA mode and circular buffer. I need to get an ISR on HalfComplete and Complete transfer.HAL_I2SEx_TxRxHalfCpltCallback is fired on half compl...
