Hi,On an Stm32f4 based board, we have the external crystal (8MHZ) mounted. The Firmware however uses HSI clock. Does the HSI drift have an impact on CAN communication with another device over a long period of time(say weeks)? Is it recommended to use...
Hi, I am experiencing a problem on the STM32F411RET6 and STM32F411RCT6 MCUs. When programming these devices I am getting a repeated "Target is not responding, retrying..." message until the debugging session shuts down and exits. I have managed to na...
Hello everyone,I have recently been trying to get the CAN1 bus working on the STM32F427. So far, however, it has not worked in either loopback or normal mode. For the normal mode I had a CANCaseXL Analyzer available. The problem, however, is that not...

Hello,I am developing project where I need to do some image processing on BW image. All was great, but I started having problems with DMA (maybe I always had, don't recall)Idea is that I simply load data to internal SRAM with DMA, and when I get TC, ...
Hi,I´m using the TCPP package (inside CubeMX). For my application I also need an ADC channel on the same ADC1 as used by TCPP to measure the Bus voltage. But it seems, that I don´t get any result in my application (configured as DMA). Investigating t...
dear：PH0-OSC_IN：12.288MHZ，duty=50%。but MCO2(PC9) output clk is 35%。can you help me？
Hello my friends,I am trying to setup an I2C slave that is being addressed with a read-request and then answers a fixed number of bytes. I was trying to find out what the XferOptions do, but after I could not find out I went through the HAL-driver co...
Hi everybody,first an apologies for my poor English.I'm using STM32G030K8 in my project and I want to use eeprom emulation to save some parameters. I used the following code, however It didn't work. I spend a lot of time but I can find the problem. v...
In attempting to figure out how to stay in the bootloader loop while exchanging packets with the USB DFU tool I came across as what looks like an unintentionally undeleted line of code.Here is the code:static void OPENBL_USART_Go(void) { uint32_t a...
