Migrating code from IAR to GCC: __no_init, __ramfunc

Hey,I am trying to modify some compiler/linker directives from IAR to GCC. I think I already managed to solve the first two obstacles:1 - In order to not initialize a variable saved in some register:static volatile __no_init uint32_t SystemInfoFlags;...

I am using EEPROM_Emulation to write flash and used as eeprom, It works fine . I can read and write but porblem is i can write(or update) it 3 times 4th time it hangs and i can't write it . what can be problem.

while launching new project, libraries file does not exist

Hi everyone, I'm tryin to learn how to use stm32f4 boards. But I have a problem when I create new project libraries file doesn't exist as it was. I did not see problem like this before while using stm32f1xx series, and also there is a warning like th...

STM32F4 USART_Receive block usage problem in Simulink

Hi everyone,I am trying to read a laser sensor through UART of STM32F4 inside Simulink. The laser sensor's refresh rate is 10 Hz approximately but it does not give the data periodically. I am using UART Interrupt for reading action. There are two cas...

How can I track the status of the onboard LED (STM32LO) and write that data to the EEPROM?

Hello everyone,I have an STM32LO discovery board. Using it for a big project in IoT. How can i track the status of the onboard LED and write that data to the EEPROM? Say the led is on, saves that status and duration, then sends it as a packet to TTN....

How to write, overwrite and read random int data onto onboard EEPROM on the stm32l072z lora, sigfox discovery board.

How can I write and overwrite random integers onto onboard EEPROM and then read the same saved value from onboard EEPROM for further processing on the stm32L072z LoRa sigfox discovery board?
