Hello! I have a problem with half-duplex in USART. I connected two boards in this mode. Gpio mode is open drain in each boards. In the first case I use internal pullup resistor. The transmission doesn't work.In the second case I use external pullup r...
f_open function are not working as it takes too much time then it is timed outI am using stm32f4-dis-bb board
I want to generate a pwm in complementary mode such that it has following specs:-1.Non inverted pwm has to vary from 0 to 90% cycle2.Inverted pwm reamins in 7% duty cycle3.Inverted pwm and non inverted pwm does not match at any instant4.Both wave doe...
Hello, I am using timer 6 and generating interrupts for every 1s.it works fine when i dont enable the sleep on exit feature. but if i enable sleep on exit feature, after the first timer interrupt , processor goes to sleep and the next timer interrupt...
Posted on July 16, 2018 at 08:00Hi I want to design CAN-LIN converter. I chose the STM32F091CC microcontroller for its LIN support. Up to this time I coded the CAN communication in the microcontroller.I have basic information about LIN. I want to in...
Hi,How to setup gpio pull? If I have INPUT, should I setup to PULLUP or NOPULL or PULLDOWN?How about OUTPUT?Thx GPIO_InitStruct.Mode = GPIO_MODE_INPUT; GPIO_InitStruct.Pull = GPIO_PULLUP;
I am trying to use the WWDG EWI on the STM32F051. I can force the WWDG reset, but never seem to get the Early Warning Interrupt. I am setting EWIMode to WWDG_EWI_ENABLE when calling HAL_WWDG_Init(). I am trying to verify the interrupt by stopping the...
Posted on July 09, 2018 at 19:25Hi,I can't find stm32l4xx_ll_tim.h file from CubeMX generated code. The only place I can find this file is a zipped file download from ST.com. I am guessing this is a Cube issue, right?STM32Cube_FW_L4_V1.11.0Thx
Posted on June 05, 2018 at 14:20Hello, I'm trying to communicate between a STM32F746G Discovery Board and a Powersupply (over PMBus).While doing so i realized that the SCL wire is kept low after the ACK Bit of the Powersupply.To eleminate possible m...
Posted on June 20, 2018 at 09:16Hey there,I have a development board that includes STM32F091CC. After write my code i successfully build it but when i try to debug in Atollic TrueStudio(Eclipse based IDE) it i have an error messages that in attached...
