Hi,I am using STM32H753XIH6 in a new design. The PCB is already manufactured, ready for the assembly. The issue is that I mistakenly designated the pins F1, F2 and G2 as NC in my schematic library model, but realized that the datasheet says they shou...
Hello everyone,I am encountering difficulties with a project. I decided to use an STM32H7B0 microcontroller, which I had previously used in other projects, for a new application. However, I have encountered a difficulty due to the signal propagation ...
Hello, I have a STM32F411 and I am ready using the SDIO port, I would like to connect 2 SDCARD to the SDIO port and be able to switch from one to another like using a CS Chip select GPIO. Is it possible ? how would I do that ? Thanks Vincent
Hi,One of our project is using the STM32U575 and we use the ADCs analog watchdog feature of the CPU. At the beginning of the project, we did not used the ADC oversampling, but for stability and reliability purpose, we have turned on the ADC oversampl...
Hello folks,I've been having a weird issue and haven't found anyone else with the same problem, so I figured I'd post here.I have a project for the STM32H735 BLANK. The PCB has an 25 MHz external oscillator (ABM8W-25.0000MHZ-8-D1X-T3) used as the HSE...
Hiin my project I have enabled FreeRTOS, so the NVIC prios 0-4 are reserved for FreeRTOS.I need to generate a highly accurate 1 sec timer interrupt.Is it correct that FreeRTOS interrupts might delay my (cortex) timer intterupt handlers to be called?I...
Hi,I need to synchronize my UART transmission with a timer using DMA. I don't want CPU intervention in fixed data transmission. My data and size is fixed. I need to continuously transmit the packet every 5ms.kindly suggest!
I am using a nucleo-F103RB. This device was functional in the past. I am getting an error Error in final launch sequence: Failed to execute MI command:target remote localhost:61239 Error message from debugger back end:localhost:61239: Connection tim...
Hello I have project where is used a STM32F103RGT6 (1Mbit flash and 96 kb SRAM) in LQFP-64 package.Is there a replacement for this MCU with more SRAM and faster clock? I found a STM32F415RGT6 with the same package, bigger SRAM size 192 kb versus 96 k...
I currently have ADC1 working with DMA at 14 MHz so my sample rate is 1 Msps I believe. I want to double my sample rate, so I thought I could use both ADCs with DMA and interleave the buffer data. My issue is that when I am trying to configure ADC2, ...
