Hi all, I'm discovering 32-bit microcontrollers for the first time. My project is almost completely working (using Timer 1 in input capture mode and all the rest is GPIO related). I want to save one variable so that it survives power down. Because th...
I have some projects that were left inadvertently with some function calls that write 0x00 bytes into the data EEPROM. They work properly. I have tested it.I detected the problem on a prototype board with an old sample of STM32L152C6T6 and this made ...
I am using IAR EWARM 9.10.2 and would like to redirect printf to UART and fopen/fclose/fprintf to SD card hosting FAT File System(R0.12c (March 04, 2017)). Any guide on how to do redirect io streams on IAR would be helpful.Thanks in advance.
I'm quite confused when it comes to alignment.I opened linker script to make some modifications, so that I can fit two binaries into flash. (Relatively new to embedded, but frankly I learn fast).I use stm32f091Rx. Which has 256kB of flash memory.A li...
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;...
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...
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...
Hello, I have installed previous version of Atollic (< 9.3) before following the official installation guide, but now it seems to be outdated since the downloadable file isn't a .tar.gz file anymore, but now just a .gz file. I am using EndeavourOS L...
Hello,I am reading out of the book, "Embedded Systems Fundamentals with ARM Cortex-M Based Microcontrollers - A Practical Approach Nucleo-F091RC Edition, 2nd Edition. (DEAN)."He reviews the peripherals on the NUCLEO-F091RC and goes into detail on how...
