Iam using stm32 IAR workbench 8.20.Iam trying to run scanf. but scanf isn't reading first character of any data type. If enter 1234 through keyboard then it will print only 234.does anyone know how to resolve this issue???
ECC uncompressed X point Public key to Y point.
Hi Sir, we need to uncompress the ECC public key. Now we are using Crypto_v4.0.1 LIB. We could use it on comx_aead&hash&ecdh API. Please inform us how to use the ECC. We need the uncompressed X point Public key to Y point.
SWV ITM Data Console not working properly
Hello,I am working on Nucleo-h745ziq board. For debugging purpose required the printf function, I can't use the UART for that because its used for another working. So using SWI I am creating the printf function but it cannot print the all the othe...
STM32L476 Locks up during Radiated immunity EMC testing
I have a design with STM32L476 microprocessor that I am having EMC issues with. The processor is locking up at 100MHz to 240MHz radiated immunity EMC, 10V/m, and not recovering. Product Architecture is that there is an external 24V supplying power to...
Hİ Bros, I am trying to read the weight from the HX711 amplifier with the STM32F407VG Development board.
I'm following the 'value' variable in the code below from the STM Studio interface. When no pressure is applied, the 'value' variable starts from a fixed number (3.62049). When I apply pressure to the Load-Cell, the digit of this value changes after ...
Resolved! [SOLVED FOR NOW] HAL I2C and HAL SPI not initialising correctly when using a custom static library that houses HAL Library
Hi,I have multiple projects that use the same code but use different processors (STM32F4xx). To try and solve the common code problem I have created a static library, this has the HAL driver code inside and the main applications for each processor li...
H7 SPI Issue: 4us delay between enabling SPI transmission to starting the clock. How can I reduce this time?
I use a STM32H723VGT6 as a master in a critical SPI communication with another microcontroller (critical because this mcu is very strict in the SPI timing, especially the time between CS and the start of CLK, and I cannot operate on the firmware of t...
STM32F407 hang and watchdog doesn't reset
Hi everybody,I'm sorry for poor English.I'm using STM32F407VET6 in my board and I set up watchdog timer. However sometimes microcontroller hangs . Here is the main loop of my code:while(TRUE) { // ====================================== ...
