Hi,I am using random number generator of STM32F407VGT-DISC1, which generates values between 0 to 4294967295. In order to make sure if I get random value for debug purposes, I want to write this value to serial console via UART. When I write my code a...
Hey there :)I am having trouble running the nucleo (NUCLEO-U5A5ZJ-Q) as an I2C slave where read/write sizes are unknown (only known by master)For the configuration I am using CubeMX and most of the time the slave is working quite fine. However someti...
Hi,I'd like help to understand what is thew PWM frequency.As far as I understand:1. The main system clock is 64MHZ -- see below SystemClock_Config()2. PWM frequency is 64KHz (= 64MHZ / (1000 - 1))BUT, measuring the frequency shows 4KHz (rather than 6...
Hy guys, I want to be able to create a named file in an SD card based on how many files I have in the directory, per example: if I have only 1 file "file1", I'll create the next one as "file2". I searched the ff.h library, but didn't find anything th...
Hi all,AbstractWe are developing our product based on STM32H7. We would like to use the HTTP server and Netconn to update the firmware for our product. We consider this method easy to use for customers more than Serial or USB. We have tried looking f...
Hello everyone, I have STM32F407 and RJ45 connector i want to establish a ethernet connection using this rj45 connector so that i can send and receive data through tcp/ip or UDP using RTOS. can anyone help me to get start. Any leads will thankful. T...
Hello,I have been trying to connect my STM32H573I-DK to our web server for some time now, unsuccessfully.I am basing my secure application on the X-CUBE-AZURE-H5 Expansion Package project.I can successfully run the example and connect (and publish) t...
Hi, I'm a student that want to integrate a logger in my project: I configured the fatfs middleware and i tried a lot of different libraries but none of them worked for my nucleo-f401re. When I tried to import the libraries, I had a lot of errors that...
Currently I am trying to interface with a LM75A temperature sensor using the STM32F446RE nucleo board.From the datasheet of the LM75A, I gathered that the sensor, returns a temperature measurement without any configuration.So I tried to simply hook u...
After 'fighting' with the speed (performance) of the HAL_UART drivers used in Interrupt mode (_IT) in a complex FW system (using RTOS and many other interrupts and peripherals), I have realized three issues with the default HAL UART drivers:They are ...
