we are configured that pin as Input. We got 0.5V drop at PA7 pin after flashing code.Please let me know the resistor values for all GPIO pins
Hi,First of all, I apologize for my English level, I am not a native speaker. I hope you can understand me :) Explanation:1) PHYSICAL WORL: I have searched for information on the electronics behind the memories. In 32 bits microcontrollers, the memor...
Hi,I am using STM32H7 Nucleo board. I soldered an external 25MHz crystal oscillator with 22 pf capacitors(Load capacitance of crystal =20pf) but the controller doesn't seem to work on 25Mhz crystal oscillator. I tested this by blinking an LED at 1 se...
I am having a little difficulty getting a USART 2 signal to output to a logic analyser using transmit Tx serial asynchronous communication. I have configured a USART 2 peripheral to communicate through a DMA. The GPIO pin PA2 is outputting a constant...
Dear Sir, Debug and driver folders are not created in code generationDebug option is also not highlighted in menu button.Below is the screenshot of that please help.
Hello,I have a problem with EXTI0 after a compilation with 03 or Os.In an ISR (EXTI0 for exemple) the place where the __HAL_GPIO_EXTI_CLEAR_IT is made seems to influence its action. If it is immediately followed by an exit from the ISR it does not wo...
Hello Everyone!I have thoroughly understood touch sense controller peripheral of STM32F051C8T6, I have also developed a test code using the HAL layer and is working file and detecting touch (i.e. is count value decreasing when finger comes near elect...
Good day, I'm trying to interface the STM32F401RE with a DS3231 RTC module. The idea is to read from the time-keeping registers of the RTC module. Based on the code, I decided to set the 'hour' register to 6 and when the register is read, 6 is expect...
HelloI am basically designing an interrupter for plasma arc speaker. I have a small signal amplifier which I connect to STM32F746 and perform FFT to determine which note was played. Whole process takes about 2ms. My transformer works with 25khz. I wa...
Hi,I need to write some data in the flash memory of my STM32H743ZI MCU, for example serial numberCan I write this data in something smaller than a whole flash sector ?Regards,Gabriel
