I was looking at some slides that I found called STM32H7- CORDIC co-processor (CORDIC, Revision 1.0) and noticed the following on slide 6: According to this, the fractional number being represented by the fixed-point integer bits is (-1)^s multiplied...
I have a written C# windows application that receive data continuously from MCP2221A. MCP2221A receive data from STM32 UART through receive data line. When the laptop goes for sleep (in battery mode), it send a suspend signal (it will go low) to the ...
shall we able to configure stm32g431mb gpio to high impedence state when configured as output pin. We need to access output pin in tristate mode
Dear all,Apologies if this is a naïve post.I am trying to find a processor for the product that I am working on with larger RAM and FLASH but it must remain pin compatible to minimise code changes. The current processor is this "STM32F756ZGT6". With ...
We are using STM32H743IIK6 microcontroller. There are analog only pins, designated as ANA. What is the use of these pins? Also, what will be the difference when GPIO is used for analog functionality and ANA pins are used for the same purpose?
Hi.I want to acquire data from a 5M pixel image sensor (for example OV5640) with YCbCr4:2:2, 8bit using DCMI.(I want to process the image data, so I need to transfer it to memory using DMA)However, AN5020 and RM0481 (Rev1) mention a maximum of 2048*2...
Hey, i got this STM32G491MET6The datasheet does not really help here to identify pin 1, since there are 4 markings to see. Anyone has a clue on this? In the previous revision of this datasheet, Pin 1 is bottom left . Already burnt 2 mcus because of t...
I am developing an TCP/IP Server Client application on my NUCLEO-F207ZG development board.I am implementing a function to send ADC values on Ethernet.void Client_Data_Send(void){char temp_buff[TEMP_BUFF_SIZE];volatile uint32_t buff_len;volatile uint...
Hello, i bought this board and the board was burned with sw with signal genrator and other things. Somone can send me the .HEX file that i can burned it again? i cant found this file.
Hello,I am running simple LED Blinking on STM32F446RE.I want to measure the Bootup Delay once it is Hard Reset.I have conducted the following test through Oscilloscope and Logic Analyzer.I want to know and prove this through calculation.Is there any ...
