we have several device with STM32H753, and they are talking to each other, over LwIP.one of the devices is the master who charges on the protocol communication between all other peripheral devices.the master send a ack message to each device in a loo...
I am new to stm32, I have a stm32F407VG discovery board. I tried to implement an interrupt using the user button and added HAL_Delay() inside the interrupt function. After I press the Button the Interrupt execute but it got stuck there, it is not com...

Hi :I noticed bl SystemInit called before executing movs r1, #0 in STM32Cube_FW_F7_V1.16.1\Projects\STM32756G_EVAL\Examples\FMC\FMC_SDRAM_DataMemory\SW4STM32\startup_stm32f756xx.s while after executing LoopFillZerobss in STM32Cube_FW_F7_V1.16.1\Proje...
Hello everybody!Is anybody tried to connect an STM32 to an KSZ846x (for ex. KSZ8463 - 3 ports ethernet chip MAC+PHY) chip? I have a very strange issue. I am able to communicate with the KSZ chip using MIIM and also over SPI, and I am able to start th...
Hi I made a custom board with "stm32f746". This board has a 32MB sdram (MT48LC16M16) and a "800×480" lcd. I use from STM32CubeIDE and touchgfx. I want to allocate 2MB of sdram (from 0xC0000000 to 0xC0232800) to frame buffer of lcd and I need to use r...
Hi, I am using a STM32F769I Disco board for testing the speeds of the High Speed USB as a MSC. At present, the system is working as expected as a MSC over uSD. However, my concern is with respect to the read write speed of 2.5MB/s which seems to be v...
Hi, I am using MP34DT05TR-A microphone with stm32f401re mcu. What is the I2s clock frequency required to get 24bit data at 48Khz sampling frequency. I also need to know the rate at which the data will be received from I2S?. Is it same as the sampling...
hi, In final end product we can't use the programmer for firmware update or upload the new program to chip . We need easy solution that compiled program in binary file has to be programmed in chip from SD card or USB Pendrive . In filed very difficul...
Hi,I'm currently developing a PLC-like device based on a STM32F429ZI. It works with FreeRTOS, and the I/O logic is implemented in a single C function, which only accesses a couple of buffers (the locations of which are known prior to compilation). Th...
