Hi,I am using the continuous mode of the ADC to continuously sample a channel and transfer the data by DMA. I have set the ADC frequency to 32 Mhz , and the sampling CLK to 3.5 CLK. According to the manual , the whole sampling conversion time should ...
Hi everyone, I’m working with the STM32H747I-DISCO board and its onboard QSPI flash (Micron MT25QL512ABB). I’m encountering a frustrating issue: Problem: Writes to even addresses (e.g., 0x90000000, 0x90000002) work perfectly. Writes to odd addr...
Hello everyone,I'm encountering an issue with a circuit that incorporates an STM32F103R8T6 microcontroller. In my design, the MCU's VDD domain is powered by a battery, while an external supply is used for the analog reference (VDDA). When the circuit...
Hi,I am laying out aboard with STM32L073. I would like to add a debug header and a programming header. Do you know which pins i should connect these headers to? I see that PA13 and PA14 are involved in debugging, but which other pins do i also need...
Hello, I am using the STM32F407IET in one of my projects and I have timer 1 set us as follows below currently my channel 1 is used to record the positive rises on a incoming pulse signal and what I want to do is use the gated mode to be able to tell ...
Dear All,I am a student working on a project where I'm trying to use an STM32U585 microcontroller to drive an AMOLED display with an ICNA3306 driver IC via the OCTOSPI interface. I'm quite new to this, and I've been struggling to get the device ID fr...
Looking for any suggestions.I grabbed a Nucleo_F411RE board and hooked it up to a bog standard 600PPR rotary quadrature encoder and set up a basic test program in Cube IDE. I've done this a few times with F407 boards (my MCU of choice for most projec...
Hi, I am designing a STM32G484RET into an application, and I wanted to confirm that my oscillator design will theoretically operate before having it manufactured. Target clock speed: 170MHz Crystal chosen: https://www.digikey.com/en/products/detail/e...
Hi there, I'm configuring CAN filtering for STM32Hxxx. I have several filters configured. Currently, when CAN Frame match filter it is not going through other filters.Is there a way to change filtering behavior to hit all filters that match given pat...
I'm trying to read a .JPG image file from my SD Card (FATFS) and want to use LIBJPEG for decoding it. Everything seems to be fine until I execute the **jpeg_start_decompress()** function. As soon as this ifunction is executed a UsageFault is generate...
