Hi,I am trying to assign an address to a pointer the following way:#define FM_P_ADDR 0x0807F800uint64_t * addr = ((uint64_t *)FM_P_ADDR);However, running the line will direct the execution to the Hard Fault Handler routine.What is happening? What ...
Hi,I have designed a keypad with 11 touchkey's. For this I have used TSC group 1,3,4 and 6. As FW i have used the STM32_TouchSensing_Library and I have a problem. All groups are working ok, sensing touch corectlyexcept group 1. This group has the sam...
In my application, I have a watchdog timer that resets every 45 seconds if not fed. I also have an RTC. The application records sensor samples, along with timestamps from the RTC.Problem is, when there is a watchdog reset, the RTC is re-initialized t...
Hi,We're storing some device configuration on last sector(7) at BANK2 inside internal flash memory. Sometimes device goes into state where part of this this sector is not readable by our code(generates fault) also this sector is not readable by cubep...
Suppose I use an oscillator instead of the suggested resonator for LSE. Will that even work, i.e., will the internal RTC continue to function when in battery mode? I assume that I'd have to power both oszillator and STM32 (using Vbat)?
Hi,It seems that in some events the I2C data setup time (Tsu;dat) is not respected by the MCU.Please let me know if I am wrong.I am using the I2C1 of an STM32F745 at 100kHz with the HAL library.The I2C setup was done using the CubeIDE.When using HAL_...
I use the TIM3+DMA function of STM32F103VCT6 to generate PWM. I need to generate a series of adjustable frequencies, adjustable duty ratio and controllable pulse number.Such as 10KHz, 200KHz, 500KHz, 1MHz, 2MHz, 5MHz.I modify the VALUE of TIM's CCR b...
Hi, I've worked a bit on STM32 before (STM32F7 to be more precise), so I have little knowledge about the STM platform. I normally don't need to ask question on forum because Google is a very good professor, but this time I'm not sure to have found en...
Hi everyone! I'm trying to learn how to program microcontrollers with C and stuck with trivial task.I have blue pill, stlink v2 and ssd1306 oled displayI'm trying to enable all pixes on the display via i2c: https://gist.github.com/ksevelyar/5e6c0335a...
I'm working with STM32F405, not sure if I'm asking question in right place, or if it matters... I'm working on a self-test for CRC FLASH (can't use libraries, just basic code). I notice that, for non-optimized code, the generated BIN file matches FLA...
