Posted on July 06, 2018 at 16:09Sorry for my stupid question, but this makes me really confused. I was just looking for the the bus with connected with the EXTI, then I found that APB2 bus is connected as it is shown in the reference manual in here ...
Hi, I am using battery voltage charging as a part of my project. For some reasons my voltage reading in the prototype is 1.18 V and the ADC reading in my debugger is 1.25 V. This totally different for different module. Physically all modules are meas...
Any writes, erases or reads to flash range greater than 0x8100000 fails. When I inspect the region via Memory browser in STM32Cube IDE all memory beyond 0x8100000 appears as a "?" indicative that a read is not being allowed. Being new to this control...
We are using STM32L452CEU6 with 48QFPN package and trying to enable internal voltage buffer (VREFBUF), by using HAL_SYSCFG_EnableVREFBUF(), always timeout happening in this function. Is it because of no internal volatage regulator available on the co...
Hii, I am using STM32H503RBT6 controller. I have a requirement of frequency modulation in my project. Based on a GPIO state i try to switch between the frequencies of 200k and 300k. in my configuration, by default i configured for 300k and after shi...
Hi friends, I have to use Keil uVision5 Software to flash My Source code to STM32F407VET6 development board Instead of using STM32CubeIDE.But I have facing one problem during select the clock frequency of Crystal in Keil uVision5 Software that optio...
I have a weird one. Using an STM32H723 Nucleo board. The MOSI line for SPI2 is giving me trouble. The edges are slow (see picture). All I am doing for this test is transmitting on SPI2 with nothing attached but the scope. I am using STM32CubeIDE and ...
Hi everyone ! I have a curiosity and I ask you all how to interpret ...The behavior of the ADC_ISR_EOC bit during debugging is unclear, it is reset and I don't understand why. Code :// TimerSecurity is a security timer that runs every 1 msec1) TimerS...
Hello everyone, Im working on a Program that i have written in a StateDiagram way. I have 3 buttons wired to my micro, with a strategy to avoid boucing.this a part of my program where if the button is PRESSED then we add 1 to the variable "Day". The ...
Hello,I have an STM32F746 in an own PCB design. A 128 Mb DRAM IS42S32400F is connected to the FMC pins, similar as on the STM32F746G-DISCO board. I can write and read data but there are errors which occur in a systematic way:I start writing 16 bit da...
