I've got a strange situation. I've enabled systick, but it doesn't keep time unless the CPU is active. Key excerpts:main.c: SysTickInit(sys_clocks.SYSCLK_Frequency);void SysTickInit(unsigned base_freq) { SysTick->CTRL = 0; // Turn it off. ...
Say, I have a STM32L431RB (128k,64k) on a board design. This is the lowest flash size on the 6 chips on the STM32L4x1Rx 64pin variety. It certainty looks like I can drop-in any of the larger flash/ram chips as the pin outs all look the same. But do I...
This is my first time working with STM32H7B3IIT6 MCU. I wanted to make a led blink application, but the program is HAL_Delay(); it goes into an infinite loop and doesn't exit.
Hi,I have questions about LSE Drive (STM32L0).1) In RCC register are LSEDRV[1:0] bits and I am not sure if I understand it corretly.From datasheet about these bits: They are cleared by a power-on reset or an RTC reset. Once “00�? has been written, th...
Hello dear STM32-Community,I'm using an STM32L4R and wanted to configure my data retention of SRAM2 for standbymode.I did the following changes to the linker file:/* Highest address of the user mode stack */ _estack = 0x10004000; /* end of RAM */ ...
i am trying to use Stcube programmer in ubuntu by when i press connect button program is crashing i am attaching log file thank you
I intend to use CAN module in STM32F722ZE Nucleo board, but I have a problem- the CAN module does not work. I tried to see the example code, but it also is not run. Anyone has the source code for CAN module in STM32F722ZE Nucleo? ( Loopback or normal...
Hello, I want to generate an interrupt using the timer update event every T seconds at a given MCU frequency F using LL library and a basic timer with STM32L071CB.Lets say for example that:T = 5 sSystem clock frequency F = 32 MHzTimer TIM6 It look...
current tick count is say 0x0fffffffff (just 15 short of an over flow) and if my delay (wait) is say 20. Running count will rollover after 15 ticks and becomes 0. The new comparison will 0-0x0fffffff. Will the delay still work? I guess not. Your valu...
