How many clock cycles should it take to write to AXI SRAM from the M7 core, assuming that the cache is disabled (and disregarding instruction pipelining)?The reference manual says:"The system AHB SRAM can be accessed as bytes, half-words (16-bit unit...
Hi, i am very new to microcontrollers and have a problem that I cannot understand.I use a STM32F407 on a Discovery board. I set up channel 1 and channel 2 of the TIM2 timer for input capture. As soon the execution jumps into the interrupt handler "HA...
I have soldered MCU chip to a PCB and programed it by ST-Link using STM IDE.when I run MCU using ST-Link it is working fine. But When I use an external DC supply it's showing malfunction, (most of the time not working). I have connected the BOOT0 pin...
Hello,I want to setup a STM32F745IEK6 together with an SDRAM from Micron Type MT48LC8M16A2P-6A.I analyzed the theoretical signal Intergrity for the devices and I had to end because of my question:The setup time of MT48L is required with min. 1,5 ns. ...
Hello, I have a software that has been workingfine for several years on a STM32F100VCT6. However, today we are trying to use thissoftware on the MCUs ref: 100VDT6 or 100VET6. On these 2 new references no programming problem with the same binary file....
Please see post over on Arduino forum (since I can't post all that text here) but feel free to reply here.
According to the data sheet, the calibrated values for specific chip (at 30°C and 130°C) are at the following addresses:#define TEMP30_CAL_ADDR (*((uint16_t*)0x1FFF75A8)) #define TEMP130_CAL_ADDR (*((uint16_t*)0x1FFF75CA))Therefore the calculation s...
I am new to embedded C, and I recently watched some videos about volatile qualifier. They all mention about the same things. The scenarios for the use of a volatile qualifier :1. when reading or writing a variable in ISR (interrupt service routine)2....
I'm trying to write and read some data into flash. But not work. Anybody help me?I'm using Cubeide and STM32F429 board.char test_data[]="TEST";char test_data2[5];uint32_t PAGEError = 0; FLASH_EraseInitTypeDef EraseInitStruct; EraseInitStruct.TypeEras...
