I am using micro switches in my system with the GPIO EXTI. I would like to detect only the press of the switch, but the interrupt was triggered on both press and release of the switch. The interrupts were even triggered twice on each press and releas...
Hi there ! I start a project with STM32G031k8. This board i'm gonna make is a RS485 slave on the pin 4-5-6-7 of GPIOA i put a dipswitch with pullup resistor , and i read in this way: uint16_t Add = ( 0x00F0 & GPIOA->IDR)>> 4 ; right now my add is 5...
I am using the STM32 Nucleo F411RE, and have 5 GPIO pins set up as inputs, each set to trigger an interrupt on the rising and falling edge, configured to use the internal pull down.However, what I am finding is that causing a level change on one of ...
Can anyone help me with debounce code in C for Rising and falling edge interrupt??
In order to mute the COMP for some time, I deactivated the interrupt with HAL_NVIC_DisableInterrupt(COMP_IRQn) and re-activated after a certain time respectively.In between I am in STOP2, some uA normal consumption.Now, while the interrupt is disable...
Hi We use an STM32L452 with an external LSE (32.786 kHz) oscillator. We would like to use PC13 as a GPIO input with interrupt. In the errata sheet for the STM32L452 (ES0388 Rev9) I find the following entry:“2.2.12 PC13 signal transitions disturb LSED...
I set up EXTI so I get interupt on the correct pin GPIO B.6. But I cannot get it to wake up from stop1 mode. I call WFI and RTC wakes upp the processor regularly but EXTI will not. Reading the reference manuel it says any interupt should wake the pro...
i want to add some work on food_recognize.c in fp_AI_VISION ,I want to use CN9 analog to control some leds but it doesn't work in first place. I can't control those pins with writegipo.so far i only see A0 always on and A1-A5 always off. On the same ...
I developed a 62.5kbit synchronous self-clocked (similar to SDLC) communication firmware for STM32F412, to be interfaced with an old device via RS485.It works in "bitbanging" using a 16us interrupt timer (TIM11) to sample the bits and EXTI0 (PB0) int...
Dear STM team,I am debugging the chip since hours and I think there is something wrong with the PB5 and PB15 pins:1. SPI1 with MOSI on PB5:I have configured SPI1 and want to get the SPI1_MOSI on PB5 (as mentioned as ALT5 in datasheet).I use a STM32U5...
