Hi I am using below controller in one of our designSTM32G474CET3 i would like to know minimum external clock frequency on which my microcontroller works. Also my requirement includes 1 SPI, 1 I2C and 4 ADC input sensing. I would need very minimum ext...
Usually, fresh (no firmware) STM32 MCUs will be in bootloader mode by default without needing to toggle the boot and reset pins. In such cases, we proceed directly with the firmware update procedure using the default slave address (0x5d).However, we...
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...
Hi,couldn't find any STM32 dev kit that has DSI display interface and a demo where it plays video (or at least graphics) directly from SD card using DMA.Which ST dev kit does that? Thank you
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%?
