Hi.I'm looking for some answer which I can not find anywere.What is the time between instruction execution time consisting of writing '1' to GPIO->BSRR of any pin and port and real mcu pin state in case when HCLK is e.g. 72MHz and APB2 is 4,5MHz (APB...
As i state in the title, what is the best way to detect a connection to a console app on a pc?I want to include a while loop in my program, that stalls the main program until the user establishes a connection and the program proccedes to the super lo...
Hello, I am using STM32f407IGT6 with Keil uvision and HAL library. When I try to connect the device with ST-Link and flash the software using the JTAG interface, I always see "can't reset the core" as the error.BOOT0 - Connected to GNDBOOT1 - Connect...
Hello guys. I'm fairly new to stm and i've mostly worked on a pico.The thing is that i want to create a programm with the following function.The user sends a character and then a string from a python app on my pc. The first character is a pseudo hand...
Hi, I want to make I2C By GPIO I/O Ports Using STM32F103RBT6 64 Pins.run my source code result is above figure.When I2C Input Read time, It Can’t read data how can I get input data? Start_Setup_Time(); // b7 ~ b1 Addr + bo_wr + ack Setup_Addr(0x...
I found a very serious problem while using BOR, which caused my program to be erased innocently.At least 0x0800 0000-0x081f ffff is like this,This is the result obtained by jlinkI need to use the BOR function when I power on, originally this function...
Posted on October 28, 2017 at 21:00 Custom board based on STM32F429ZI with Microchip USB3300-EZK HS PHY. The clocks and USB connections modeled on the STM32429I-EVAL1 schematic. I've verified that the CubeMX-generated code for my board looks just...
Hello, i ordered a STM32F429ZGT6.Now i try to identify the revision of the chip i got.The marking on the package seems to have changed - there is no ARM Logo anymore.And where the revison was printed in the past there is now a QR-Code.Is 340 the date...
Hello, I am using a STM32F334 for a project where I am reading several analog channels, specifically connected to thermistors. I am using DMA to read the analog channels and also sending this data out on UART via DMA. I am seeing some weird jumps in...
Hi,I have an STM32H747IGT6 that I wish to:Continuously sample 4096 ADC samplesTransfer each sample from the peripheral to memory using DMATrigger an interrupt at the end of the conversionsAfter the CPU operates on the stored data, restart the process...
