I have an application running on HSE as system clock..and I set the multiplexer to select HSE, totally not using PLLbtw, should I put any configuration to my PLL? such as PLLON =0, and while(PLLRDY==1) , to “properly configure�? the unused PLL?Or sho...
Resolved! Could ADC+DMA brick my mcu?
I was happily developing some ADC+DMA routines for my stm32f205 and suddenly my MCU started to freeze.I am able to connect, erase, and flash binaries with stm32CubeProgrammer trough an ST-link.After erasing multiple times my STM32F205 with stlink and...
STM32G071 write protection, bricked MCU flash
Hello, MCU bricked after I tried to remove write protection. Now when I read the flash it shows only 0xFFFF0080. Read the full description bellow. We are making new project using STM32G071.We use serial communication custom bootloader so we can updat...
Resolved! Reset timer output compare output with timer in one pulse mode
I am using an STM32H742 MCU and have a timer with an output connected to the output compare function. The timer is triggered from another timer and set to One Pulse Mode. Basically I want the output to go high and stay high once the compare value is ...
DMA unexpected work on stm32g071
i want to use dma ch2 to response a request of Req_CC3 to load a new value to TIM1 CCR1 or CCR2 . i need dma in some turns but not always so i choose nomal mode. i'd like to know if dma request is accumulated in stack or somewhere. caus...
How to find the address of the BLE advertising device?
I have to extract the RSSI from scanned packet w.r.t to its device address. I got the RSSI but I am unable to get the actual device address. But in the manual they mentioned that"Once the scan parameters are set, the device scanning can be enabled. T...
Resolved! When my code erased the configuration page, and the other pages is also erased
I am using STM32F103C8T6.
Resolved! Is it possible to trigger serially using timers.
For example, there are 3 timers (Timer 1, 2, 3).I want to set like below: Timer 1 : MasterTimer 2 : Slave of Timer1Timer 3 : Slave of Timer2When I checked the waveform after setting similarly to the above, it seemed that timer2 could not trigger time...
Resolved! IWDG reset
Hi,I use STM32L496RGT6 with own bootloader. If I start IWDG in bootloader and periodically reset it it is work good. If I jump to application and call HAL_IWDG_Refresh(..), function doesn't refresh IWDG and IWDG reset mcu. I tried call MX_IWDG_Init()...
