Connecting HC-05 in Master and slave mode
Before setting the device in the master mode, make sure you have another device which is in slave mode. I have HC-06 which is always in the slave mode.
Receive UART data using POLL INTERRUPT and DMA
Starting with the simplest one i.e using the POLL method. The data is Received in blocking mode i.e the CPU will block every other operation until the data transfer is complete. This method is good to use if you are only using UART and nothing else otherwise all other operations will be affected.
Getting Started With PIC16
PIC16 is a microcontroller series from Microchip. It is not difficult for a beginner to learn but powerful enough to be used in high level applications…
UART Tx data using Poll Interrupt and DMA in STM32
The data is transmitted in blocking mode i.e the CPU will block every other operation until the data transfer is complete.
