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...
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...
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...
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 ...
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...
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...
I am using STM32F103C8T6.
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...
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()...
I am working with a STM3220G-EVAL board and am using the SMARTCARD_T0 example code (from the STM32 website, “STM32Cube_FW_F2_V1.9.0�?/CubeF2 firmware.With the example code, the default value of uint8_t CHV1[8] = {'0', '0', '0', '0', '0', '0', '0', '0...
