Hi, I have a custom board based on the STM32H745 and I'm trying to understand an issue I'm experiencing with the SPI Interface. I have a BMP280 attached to SPI1 on the M4 coreand I've successfully written a driver for it both using DMAs and Interrup...
In STM32F407 locked to RDP Level 1, with a battery on VBAT, I keep some (not critical) data in the RTC Backup Registers. In an attempt to investigate an incident, I tried to read out content of these registers using SWD. While I was able to read RTC ...
Do we able to calibrate the RTC for better accuracy?
Hi, its not clear for me, does lower number represent higher or lower priority?Is "System tick timer" at highest or lowest priority?
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...
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
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;...
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...
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...
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.
