Recently we have received STM32F103RBT6/T7 samples which could not be flashed using internal bootloader. We have checked working devices and under 0x1FFF F000 they have readable bootloader firmware code. Problematic samples have FF bytes in the same ...
Hi,I am working on STM32F777 MCU LQFP 176 Package.I need to confirm if i can use FMC interface with my EtherCAT chip FIDO5200 that uses 16-bit data lines and 4-address lines.Also I need to interface SRAM (parallel bus)that has 8-bit data and address...
I have a specific requirement to capture input PWM analog signal using Timers.The timer should capture both period and duty cycle of the input signal for one pulse, then stop the capture automatically.The application can read the capture compare regi...
Hi STM,I am having short question about BACKUP SRAM on STM32F437 MCU. So, for how long will BACKUP SRAM keep data, if power supply is removed. Will the data stay there, after some long period or will they be wiped out?If they are going to be wiped ou...
I've been working on getting the STM32f7-EVAL operational to later on migrate it to STM32F767II. For this we decided to split up functionality into 3 sections, there is a forward facing application that has the main and specific business logic.Curren...
In my STM32, if I have set the GPIO_MODER as "Alternate function" and did not set any values in the GPIO_AFRL and GPIO_AFHL, I guess it will take the defaukt value of AF0. What is AF0 used for ?
Hello, I am having trouble calculating the correct calibration value for my RTC 32K osc. My setup is as follows. STM32F411. 32768 LSE osc. I am passing a 1HZ signal out of the micro and I am measuring it with a 5Mhz precision oscillator and counter,...
I'm building my application which includes the CMSIS core_cm4.h file and get an `undefined reference to `ITM_RxBuffer'` message. What file actually defines this variable?
If so, what are the reasons for the difference，If not, which phenomenon is normal? Please see picture， Thank you very much
