I am implementing an application when I need to set high a status variable when a button is pressed. I would like to do so via the interrupt routine of the push button. So, in gpio.c I havevoid HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){ if (GPIO_...
HelloI use the embedded Op Amp in STM32U585VIT3Q to charge a 47uF capacitor.The input of the Op Amp is connected to the output of DAC. The voltage level is 3V.So you can see when the Op Amp begin to charge the cap, the peak current is quite large.I w...
Hi,since some days I try to get a communication between a STM32F030R8 Nucleo and an ESP8266 WIFI module working. Communication between Putty and WIFI module works already. I am stucking at receiving the answers from ESP module. I already tryed it wit...
Hi STM32F103 ProgrammersI am fighting with my RTC. I have it working but have problems with accessing the Alarm registers for the second time. I can't find the reason why I can't.I program the RTC direct using Bit fields and when needed register bit ...
I understand that that may be the usual method for the internally handled cases, but here we would like to have them open for discussion.Thanks,JW@Jaroslav JANOS https://community.st.com/s/question/0D53W00001uKlwxSAC/i-am-using-the-stm32l051k8u6-and...
I'm using Nucleo STM32L011K4T6 kit to test different low-power features.For this, the code is executed in RAM for 10ms (GPI/Os management) then the MCU is put in stop mode with the WFI instruction, to be woken up 90ms later by the RTC (RTC wake up).T...
Hey,I am using nucleo F030R8 om window os.I connected buttons to the board and i proggramted that each push will trigger an interupt(rising and faling). However many times i can see the the unterupt callback function is triggerd twice(2 calls for on...
