In USART2 interrupt service routine ISR is read isrval = USART2->ISR;Stopping at breakpoint just before this statement, Keil debugger shows ISR value 0x000000F8.Stepping one step (to read this ISR), value in ISR changes to 0x000000D8...
Hi, I have been using STM32F103C8T6 board whose B8 and B9 pin is connected as SDA and SCL pin AD5669 I2C device and has given 5v input and grounded the sensor with STM32 boardI am using Arduino IDE and after selecting the correct while flashing the c...
I am working with the STM32F446 microcontroller and for over a year I've successfully been able to erase sectors from within my code using FLASH_Erase_Sector. Now all of a sudden my code gets stuck whenever I call it! I have looked at the Option Byte...
The evaluation board STM32F429I-DISCO has a Synchronous Dynamic RAM: ISSI IS42S16400J I must use this external RAM instead of the internal RAM so I had a look to the example from "FMC/FMC_SDRAM_DataMemory"The example looks quiete easy. Nevertheless I...
Hi,I'm using STM32L072 Discovery Board and generated UART code using CubeMx, I'm able to transmit the data via UART but not able to receive the data. Please help me in this regard.int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ ...
Hello everyone, I'm using RTC on board NUCLEO-L053R8, so I have some problems. How do I connect a battery in this board? I know that if I want save my battery lifetime I have to put my microcontroler in a mode as StopMode, but how can I do that when ...
hi i'm using HRTIM for PWM output.i could complete pwm output. but i want to stop it at pulse count that I want.is there any good way to stop output at i set pulse counts??
