Hello guys !I am new at the embedded systems and I am trying figure it out ! I am using STM32F446VET7.I connected my buzzer to an GPIO pin(PB12) which has no pwm speciliaties.But my buzzer is not working when I connected to the DC signal source like ...
HiI'm trying to working on Enabling the TCP Server on STM32 NUCLEO-F767ZI using the LWIP stack and RAW APII am able to ping to the board & also connect to it. However, when I send a text data from Hercules say "123" then I receive "123". However, acc...
I used STM32F446VET7 on the board I PCB printed. When I use HSI, I can debug without any problem, but when I want to use HSE, SystemClock_Config(); function enters ErrorHandler().Can you help me?
I can not find any instruction in documents about gpio configuration in alternate function mode. For example I want to configure SPI GPIO. Examples found in the internet have different configuration. Is it unimportant to configure push pull and pull ...
Dear Stm32 users,I currently plan to design an analog function generator and capture System.The old System used an analog lock in amplifier circuit to excite and capture noisy signals from a measurement source.For cost and pcb size saving i am consid...
Hi,I´m running ADC1 (IN1, IN2, IN6, IN7) with DMA process. Everything works fine. But if I try to initialize afterwards the DAC1_OUT1 (normal or DMA - both tried) I get a hard fault. Is there a general collision between DAC and ADC or would could be ...
I have faced this issue, all the parts of my MCU registers are null. If I press "step over" button, it goes right, but when I press "resume" button, it goes as the following picture. I notified this issue when I was implementing a LCD project. I have...
Hello,I have an STM32L432KCU chip that's on a custom board. I have exposed SWD pins for debugging and flashing. Currently I'm only able to flash and debug the chip if I supply the STM with 2.2v from my external power supply. If I run the STM at the s...
I have been trying to figure out which code exactly needs to be put in SRAM4 memory region for the LPBAM tool to work. All the examples I could find only use SRAM4 and fail to explain which parts are strictly needed to be placed in that part of the m...
For a project I am using a number of timers to generate and/or monitor digital signals in a custom protocol. I stumbled upon a glitch in a timer Output Compare channel which I would like to share to find whether this is recognized and if there is a p...
