Dear Community,I am currently facing this issue where my STM32 Black Pill F411CE suddenly went into hard fault during runtime. The MCU was permanently gone and was not able to be re-programmed, and four others that I connected to the same hardware we...
Hi,We made a board with STM32G473CCU and we are using OPAMP2 as follower internally connected to ADC2 to read a thermistor currently at 720mV. We find that the value given by ADC reduces if we read continuously and only becomes stable if we wait at l...
hello everyone, I am having a problem with my stm32H745I board testing code for the RTC,RCC and power supply it seems that it stopped working. At first it wouldn't let me upload code until with stmprogrammer I connected by holding reset. Now I can up...
Hi,I have been banging my head for a while now and decided to reach out for help. I am trying to get the IWDG to freeze during Standby. Based off the reference manual I have toggled the IWDG_FZ_SDBY bit to 0. In STM32CubeProgrammer it is set to 0 so ...
If I want to the timer to run for 10s, having the system clock running at 240Hz. What value should I choose for the prescaler and counter period settings. I want to know the process to calculate the above values?
When flashing the program, CubeIDE shows "Successful", but functions are not realized. We have checked the connection between PC, STM32, DAC(AD5791) and power supply is correct, but the LDAC pin of DAC keeps showing "high" and the pin on STM32, D1, w...
Why is the high level range 0.7VDD~VDD and the low level range 0.3VDD~VSS in Table 21 of STM32F103xC, STM32F103xD, STM32F103xE (DS5792 Rev 13), while the rise time in Figure 19 ranges from 10% to 90%?
We have been using the STM32H735G-DK eval board for a while with no issues with the STM OCTOSPI interface which is connected to a S70KL1281DABHI023When switching to our target we had to change to using a S27KS0642GABHI020 HyperBus RAM device.We have ...
Hello, STM32 community,I’m currently working with the STM32U5 and using the DCMI (Digital Camera Interface) to interface with a ADC Module which has a pixel clock and outputs 14-bit parallel data. While I understand that the DCMI supports extended da...
This code doesn't write anything:*(__IO uint16_t*) 0xD0000000 = (uint16_t) 0x01;However, this code does write:*(__IO uint16_t*) 0xD0000002 = (uint16_t) 0x01;As you can see, the only difference is the 2 vs 0 at the end. The 0xD0000000 address is defin...
