Hi Team,I want to retain a value of variable after software reset i tried __no_init but variable was resetting to zeroIs there any way i can write into Flash during runtime and fetch it back after resetThanks,Krupashankar
I am using STM32F030F4P6. VREFINT is supposed to be calibrated at 3.3v +/- 10mV and 30 degrees C. In my application the VREFINT calibration value is 1543 meaning the reference voltage is 1.243V (3.3/4096*1543) this is on the high end of the spectru...
I'm getting above error both of the two STM32H735G discovery boards that I have. On both boards ST-Link worked fine for some time until I unplugged the ST-Link USB connection while the MCU was stopped at a breakpoint. Afterwards it seems impossible t...
Hello!Can a binary created from code for the STM32F767ZIT MCU run in the STM32F777ZIT MCU?Are they 100% pin compatible?Thanks!
Hello,I am trying to use USART2 TX-PA2 RX-PA3 with 115200 baudrate no parity as shown in the cubeMx settings.'u' in binary is 01110101's' in binary is 01110011I have generated the code bellow. and i got a photo of the scope signal as shown bellow....
I would like to be able to read the BOOT0 pin level at boot.I tried the following. It reads the BOOT_MODE from the SYSCFG register:// Turn on blue LED if BOOT0 is low at boot if (__HAL_SYSCFG_GET_BOOT_MODE() == SYSCFG_BOOT_MAINFLASH) { // BOOT0 pin...
Good afternoon,Maybe is an obvious question.I'm studying the default startup_stm32g030xx.s, a part of the syntax is figured out in the program manual of MCU and another part in the GNU AS command page.But, for example, those following commands: .synt...
Hi,From the data sheet of STM32L072xx it is mentioned that Tvrefint start up time is 2-3msec. When using Vrefint in comparator, does controller take 2-3msec each time to compare input with Vrefint or it is just the initial start up time?Because I hav...
