Dear,I use STM32L071 powered from serial 2xAA 1.5 V battery (3 Volts). I intended to use PVD to reset mcu when the VCC is dangerously low, but the lowest threshold to activate PVD IRQ is 1.9 V. Problem is that for me is shame to reset whole MCU at 1....
Hi,I am trying to interface 4-bit SDIO with STM32L452 Nucleo board.So far, I have tried CubeMx and SDFAT library, but it doesn't seem to work.I have tried same interfacing and library with other variants(STM32F407) and its working fine.Is there any i...
HiI'm using STM32F103VGT6 and now days i have a problem in working with SD cards.I can't use FatFs library."HAL_SD_GetCardState" function, always return 'TRANSFER' state.I try multiple SD cards, clock divider and any many configs.please help.thanks
I've been making decent progress on learning how to use C/C++ to replace an existing C# embedded application. I've cut a few corners along the way and I'd like to see if I can clean up the worst ones. Right now I have an ISR getting pressure data f...
I have been spending a few hours debugging my STM32G431KB Nucleo USART2 Rx not working and have found that the chip pin PA3 is not wired to the header A2 (or 11). Tx on PA2 (A7/5) works fine.Am I missing something? I ended having to solder a wire ...
Hello Community,I am trying to post-process my just sampled ADC values with the DFSDM sinc-Filter and mainly the oversampler.The problem ist: My DFSDM doesn't output anything. I tried DMA and polling. Polling generates a timeout.I configured the ADC ...
Hello,if I start a filter with DMA enabled using method HAL_DFSDM_FilterRegularStart_DMA(&filter1, buffer, bufferLength), then the filter output is not right shifted. The right shift works, if polling and manual result query is used.I cannot find thi...
Hello community,I am working on a STM32L562CETx micro-processor and testing out basic functions. I only use the internal oscillators, no external is connected.I managed to en-/disable GPIO output pins to drive LEDs etc successfully. The Problem is:Us...
I have 3 pictures 544K in size (ARGB). Please write in more detail how each time do not overwrite the data to QSPI during debugging. The reading of the IAR HELP "Linking using ILINK section" did not add to the understanding.Thanks in advance. Sorry f...
In the interrupt of serial port 1, data is output in both serial port 1 and serial port 2. Serial port 1 first sends data, then serial port 2 sends data. After serial port 1 outputs a few frames of data at the beginning, there is no data output, whil...
