dear experts i am working on stm32f030c6t6 MCU i want to calculate the adc measurement of sine wave form at Gpio pin and that gpio pin has a adc channel also i am using the DMA here i am using another Adc channel for other purpose please check my cod...
Resolved! USART 2 Transmit not working
Board : STM32F746GI configure USART1 with same configuration. USART1 is working fine. I did same configuration for USART2 also, but USART2 not working. I don't know what's happening.Thanks Manikandan D
Push button: is there a need for software debouncing?
Hi. I am trying to trigger and external interrupt using a push button (rising edge trigger and use internal pull down). When the push button is pushed, the variable cnt should be incremented and the pulse width of the PWM shall be changed according;...
Incorrect RTC operation in STM32L073CZ
Good afternoon.I have developed a device for collecting data from sensers and storing them in external memory.During testing, I revealed a failure in the operation of the device.Investigation of the behavior showed that there is an error in the RTC o...
Resolved! Can STM32G4 DAC be use along with internal OPAMP to connect to headphone directly ?
I want to use the STM32G4 DAC along with its internal OPAMP to connect to the Headphone jack directly without the need for an audio IC, is it possible ?. This is my first time implementing such type of function hence I am unaware of the details or be...
MCU boot
I designed Control card using stm32f205vet6 and it working good. But when I changed MCU to stm32f205vbt6 I have boot problem. boot address is 0x1fff3de4 so MCU is not working.
High jitter on MCO output?
I just got my NUCLEO-H723ZG board, I loaded the GPIO_InfiniteLedToggling example project, downloaded the program to the board and it worked fine. Then I added a very simple code to output the HSE clock to an MCO pin. /* Enable the MCO1 Clock */ LL_...
Resolved! Solved; STM32F437VG: remove AF for a JTAG pin (pin 0x0F) make it be a GPIO.
I use `HAL_GPIO_Init()` to configure my GPIO pins, setting my `GPIO_InitTypeDef` structure initially to zero and then configuring the Pin, Mode, Pull and Speed parameters as I require but leaving Alternate at 0 since I do not want an Alternate functi...
