Hi, I am following the instructions in STM32 reference manual to configure VREFBUF to use in my ADC measures. In chapter 17, it explains that it is needed to set ENVR to enable VREFBUF, then reset HIZ and set VRS (in my case for VREFBUF = 2.5V), then...

Enable and use VREFBUF for ADC measures

Examples about USART serial communication (TX and RX simultaneously) with FreeRTOS. I am trying to adapt the examples in documentation (e.g. P-NUCLEO-WB55.Nucleo\Examples\UART\UART_HyperTerminal_DMA) to use them into FreeRTOS task but it is not working.
