How to know what cause Error_Handler?
Often trip to Error_Handler from usb_device.c and usbd_conf.c.void Error_Handler(void){ /* USER CODE BEGIN Error_Handler_Debug */ /* User can add his own implementation to report the HAL error return state */ __disable_irq(); while (1) { } /* USER CO...
STM32F429 to STM32H7A3 migration
Hello There,I'm looking to migrate from STM32F429ZIT6 to STM32H7A3ZIT6 for a TFT application.I have checked H7 will provide better performance on this.There is one more thing that comes to my mind that H7A3 has better specs than F429. Then why F429 p...
Resolved! Nucleo-U575zi-Q ADC reading garbage values
I'm new to the stm32MCU. I am using a Nucleo-U575zi-Q board. I am trying to read ADC values by setting the built-in DAC. I have check my DAC out and it is working fine. My ADC reading is giving me garbage values. I have set HAL_PWREx_EnableVddA() als...
Debug problem
Hi, I have a problem where I cannot debug my code bcs of this error. Anyone know how to solve these problem?btw im using the STM32H750VBT6x for MCU and ST-LINK V2
Resolved! STM32L4 current consumption is more than expected.
I am working with a NUCLEO_l452RE, temperature 25°C, 1.8V, and I am measuring current on JP6, so I tried to reproduce: I set up MSI@1Mhz, I got 280uA, much more than 100uA which I was expecting.Later with MSI@24Mhz, I got 3.24 mA, 135uA/MHz, closer t...
Resolved! PWM Input capture reset behaviour
Hello,I have a question regarding several timers which are confiugred in PWM input mode (CCR1 is used to measure the PWM period and CCR2 is used to measure the PWM Width). So far when I plug a user signal on the evalution board, I can see the correct...

STM32L552, relocate IRQ Vector Table
We are porting code from a STM32L4P5, where we relocate the IRQ VEctor Table with memcpy(g_RamVectorTable, g_pfnVectors, sizeof(g_RamVectorTable)); __HAL_SYSCFG_REMAPMEMORY_SRAM(); // not implemented on STM32L5xxthat works fine, but as commented ...
