I have a problem with DMA on this board that was not present on an F407 using code generated by Cube.I2S2 has been configured as master half duplex and IS23 as slave half duplex (fed clock and WS of I2S2). The plan was to have a MEMS microphone on th...
Hi,We were planning to use ST32H750VB (LQFP100 Package) in our design. The critical interface in our design will be SDRAM ( planning x16 bit).But while checking pin-multiplexing details for LQFP100 package, we observed that the D[0-15] and A[0-15] ar...
Hey there.. iam currently working with a L432KC on a custom made PCB.My programm reads a sensor value (I2C) and sends it so another device via SPI.This operation is performed every minute.iam using the HAL_Delay(60000) command to wait fot the next mi...
I had an issue with a STM32F103RB connected to a poor Power Supply with slow Ramp-Up.In this case, the CAN Peripheral was not correctly initialized. After adding an external Voltage supervisor the Issue dissapeared. My question: is it also possible t...
Hi all,I am trying to run the OSPI memory mapped example found here on the STM32H7B3i-DK board but does not work correctly.There seems to be a corruption during the comparison block of the code mem_addr = (__IO uint8_t *)(OCTOSPI1_BASE + address); ...
The nucleo ported project doesn't work , i cant understand what could be the issue . I keep getting verification failed error , HAL_TIMEOUT .The download timeout is 10000U ,changes made to it (50 seconds) how does this impact the code, will it wai...
I have an issue where CDC transmission from an STM32L4 is dropping or duplicating data.Here is a simple test case that runs from main.c extern USBD_HandleTypeDef hUsbDeviceFS; static uint8_t UserTxBufferFS[100]; void TestSerial() { // connect ...
Hi every one! I work with STM32 Nucleo H755ZIQ development board. A dual core MCU with 2MB of flash and 1 MB of Ram. I need to first store data the size of which is around 512KB on Ram and send the data set to a Wifi module. what I need is to see ex...
Hello, I am using a Nucleo-f401re Board and unfortunately I have serious troubles with External Interrupts. I have two inductive sensors which are supplied by 24V. These sensors shall trigger an external Interrupt when the controller detects a rising...
This seems like it should be pretty straight forward but I’m still struggling. I have a project that started from the STM Nucleo413ZH RTC Calendar example. I did set it up in the embedded project wizard as a C++ project. I changed main.c to main.cpp...
