Posted on October 12, 2017 at 17:10Ok, quick background first. I am using RTC ALARMB to have a timeout queue that survives STOP mode (which SYSTICK does not).My PREDIV_S is 2048, PREDIV_A is 16 in case this matters.The code that I am using can run i...
Posted on October 12, 2017 at 10:04Hi,trying to transmit data via USART1 of STM32L476 Nucleo evaluation board. Use PA9 for TxD.Character count is 254*2+14 = 522 or 255*2+14 = 524.522 always is ok, 524 gives errors at receiver site.Data switches b...
Posted on October 12, 2017 at 16:30Not a question, but an observation. I am using the STM32L476G-EVAL board with STM32Cube_FW_L4_V1.9.0 and noted that within the call to HAL_SPI_TransmitReceive_DMA(), if calls to HAL_DMA_Start_IT() do not succeed fo...
Posted on February 27, 2017 at 12:09Hello,even so e.g. OPTCR1 seems to to be used on STM32F401, system headers define values with OPTCR1. This pollutes the headers.
Posted on October 12, 2017 at 14:26Hello,I am using stm32f4 discovery board, but when I am trying to connect the board to pc I am gettingerror: 'One of the USB device connect to this system is malfunctioned'.In device manager error is ' Windows has ...

Posted on October 11, 2017 at 04:32Hello, I am going to use the internal RTC. However, there are a lot of errors when using the internal RTC. I wonder if there is a way to reduce errors.I don't know because I'm a beginner. Thank you for giving me a ...
Posted on October 11, 2017 at 13:27Hi guys,I'm using an STM32F446 micro-controller with USB CDC stack configured as VCP.Each time that i connect a device the operating system (Win 7) assign a new COM port number to the connected device.I know it's a...
Posted on October 10, 2017 at 15:34Hello,We are planning to use STM32L072RB microcontroller in our device.We have implemented USB type c connector on our board. STM32L072RB microcontroller has USB 2.0 support.So how to interface microcontroller USB ...
Posted on September 19, 2017 at 09:44Hello , i try to make a program scanning a keypad 4*5 with stm32F100RB so i have to use 5 inputs as pull up (using internal resistor of the mcu ),after initiating with cube i got this /*Configure GPIO pins : K1_I...
