I am porting a code written for the stm32f4 to stm32l0. The code uses the ll diver to configure USART1 with the following statement:LL_AHB1_GRP1_EnableClock(LL_AHB1_GRP1_PERIPH_GPIOA)The LL_AHB1_GRP1_PERIPH_GPIOA value is not defined for the STM32L0....
There is a race condition bug in FreeRTOS 10.1 that currently ships with STM32CubeMX. A fix is available but users must manually paste it into their build system. It would be helpful if ST could integrate the bugfix into ST's shipped version of FreeR...
Is there a way to implement a feature of suspend/resume on usb HS on STM32F7?Or, turn off internal power to USB HS port?
Please advise if that is possible and if not what will be the best way to implement MQTT IoT Cloud Application with the STEVAL-STWINKT1 board.Thanks,Marcelo
I put my code on a nucleo board, and the loopback test works, so I don't think it's my code. This problem occurs only on our setup. I have included a schematic of our setup so you can see it clearly. The loopback mode is enabled by setting the l...
GPIO_InitStruct.Pin = SPI_NSS_Pin; GPIO_InitStruct.Mode = LL_GPIO_MODE_ALTERNATE; GPIO_InitStruct.Speed = LL_GPIO_SPEED_FREQ_LOW; GPIO_InitStruct.OutputType = LL_GPIO_OUTPUT_PUSHPULL; GPIO_InitStruct.Pull = LL_GPIO_PULL_UP; GPIO_InitStruct.Alternate ...
I am finding some ways to detect USB cable is plugged in or not and I found the PLTS seems to fulfill my requirements.After some experiments, value of PLTS is 3 and other values will appear if cable is plugged in.However I cannot understand what is t...
Hi, if I call: HAL_UART_Receive_IT, and I disable all the error IRQ (I don't want to be waken if I sleep) with the following instruction: __HAL_UART_DISABLE_IT(&huartx,UART_IT_ERR) ;The uC stops to run because the HAL doesn't manage the IRQ error if ...

Hi everyone,I am student who is new to STM32. I am trying to understand how to program the MCU and noticed GPIO_InitTypeDef data type. I went into the reference manual but did not find anything about it. Is there a document including all the function...
