Resolved! Package UFQFPN32 (5x5 mm) for STM32F302x6 STM32F302x8
Hi,The package UFQFPN32 (5x5 mm) have an exposed pad but where is the definition of this Exposed Pad in the datasheet for the STM32F302K8 K Must I connect to the GND or is it not connected or maybe another pin definition ? I can't see in the datashee...
Resolved! STM32F373 can't set GPIOB->AFRL for PB3 to USART
I'm using USART2 on PB3 and PB4 which means setting the AFR bits for those GPIO pins to 7. The CubeMX wizard and HAL GPIO libraries agree with this, but the AFR bits for PB4 stubbornly revert to 0 and my USART wont transmit. What is going on? I've tr...
Resolved! STM32G474CE wont start on debug or after power on.
Hi,I have a new project with STM32G474CE and cant get it start. If I program it with STM32CubeProgrammer it runs the a simple code for led blinking. I checked all VDD,Vref,Vbat pins and all okay. But after powering it off and on again, code gets stuc...
STM32L151RET6 is in halt state
Greetings,I have a board with STM32L151RET6. I can program the controller using st-link, but as soon as i try to enter debug mode it ide says cannot read memory. I am using keil and i am trying to enter debug modue using keil debugger and stlink.I ha...
Triggering the read timing of ADC when using DMA
I am using ADC DMA to read 100 sample from 1 cycle input sine wave whose frequency is 1KHz . When we using ADC to read DMA, the DMA reads ADC continuously until buffer is full. I want the DMA to read and store ADC data in buffer one at a time when it...
32 bit limit on chained 16 bit timers
Working with a L4R5. I have chained TIM1 & TIM3 to create a 32 bit 1mS counter.Is it possible to reset both counters on an arbitrary 32 bit value?I would like to limit the count to 0x240c_8400; msec in one week.I understand how to reset a timer base...
Resolved! VCO frequency discrepancy in STM32H743 datasheet and reference manuals
There is a discrepancy between rev 8 of the datasheet and rev 7 of the reference manual regarding the PLL VCO output range parameter when the PLL is setup in wide VCO frequency mode.In section 7.3.10 of the datasheet, the VCO output range is between ...
STM32g491KE MCU does not reset in debug mode

Resolved! Nucle-L4R5ZI Hard Fault Timer with Output Channel
I use the NUCLEO-L4R5ZI Evaluation Board.I use STM32CubeIDE with HAL and gcc.When i activate an Timer Output Channel (I have tried it with Output Compare, PWM, Forced Output) i get a Signal:0 in the gdb after the Timer init (e.g. after call of MX_TIM...
