SDRAM in STM32
SDRAMs are mostly used when we are working with large buffers, for eg while using the LCD display. Here we need to store the frame buffer..
UART DMA with IDLE Line Detection
HAL_UARTEx_ReceiveToIdle_DMA is used to receive the data using the DMA until, an IDLE event occurs, or all the data has been received…
How to communicate between HC-12 using STM32
HC-12 wireless serial port communication module is a new-generation multichannel embedded wireless data transmission module. Its wireless working frequency band is 433.4-473.0MHz
