Hi everyone! I want to have ability to program and debugging STM32 MCU's via CAN: in other words, I like to have functionality of ST-LINK (including connection via STM Studio), but using CAN, not USB. How to implement SWD master, is a any source code...
Hi,I am currently working on a large project of my own on an STM32F7 cortex-m7 microcontroller in C++ using GCC. I need to store a wide array in an external SDRAM (16 MB) containing vectors of notes structures (12 bytes each). I have already a workin...
Hello,We need to perform burst read and burst write in FMC (PSNOR) .HAL_StatusTypeDef HAL_SRAM_Read_DMA(SRAM_HandleTypeDef *hsram, uint32_t *pAddress, uint32_t *pDstBuffer, uint32_t BufferSize); HAL_StatusTypeDef HAL_SRAM_Write_DMA(SRAM_HandleTypeDef...
I testing SPI using two STM32F411 disco.One is master, the other is slave.My problem is only work MOSI , MISO is not working.I attach my Two source code.This is setting of my disco board.Do you have any idea about error of Slave transmit of SPI?
Hi,I use RTC for timing FreeRTOS (also in Tickless mode - in STOP mode) I use ALARM A in rtc. I noticed one weird behavior. Some times for examaple after 5 hours of running program the ALARM A is missed - no Interrupt of alarm happended, althougt the...
I am trying to use ov5640 camera with stm32l4r5 board nucleo-144. The ov5640 has SCCB bus which is similar to i2c. But ov5640 has register with 16bit address (0x300A, 0x300B like this). I used CUBEMX to initialise i2c pins and generated code. How can...
I am using STM32F407VG board. I wanted to know about the reference voltage and ADC resolution available on this board. I couldn't find the exact info related to these parameters in the datasheets.
Hello AllI understand that debug steps advance instruction by instruction (whether in C or assembly). I wonder if there is any way to advance CPU clock by CPU clock. I need this to debug an issue I have with the SysTick timer.Thanks
Posted on June 26, 2017 at 09:23Hello. I have custom serial bootloader, which located in the beginning of user flash (sector0), and also user application, which burned by bootloader starting from sector 1 (slightly modified IAP example from ST). Whi...
