For STM32G071 controller, I see difference in information provided in Ref manual (RM0444 Rev4) and STM32 microcontroller system memory boot mode applicate note(AN2606 Rev44).In Ref manual on Pg 60 section 2.5 it is mentioned that for selecting boot f...
Hi,I am not quite sure about this. I have a STM32L100 µC operating at 1.8V, the analog pin sees a 3.0V coming from a battery and I want to use the ADC to be able to monitor the voltage of the battery.I plan to supply the VDDA Pin with 3.3V (the VRef+...
Hello, I would like to be able to run a program without using a board. I would like to be able to do continuous integration with Jenkins but I haven't found any solutions to emulate my STM32L072. Someone would have any idea ?
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...
