Mode pin? #3

Closed panosss closed 10 months ago

Hi wdomski. I 'm trying to convert your library for use with an STM32F030F4P6. But I don 't understand what is achieved with setting or reseting the MODE_Pin.

You 're switching from master to slave the Lora module? With which pin of the Lora module should the MODE_Pin be connected? (pin PB2 in your code).

Hi

The MODE_Pin is only used in the example to choose work mode: master or slave. When you flash a board with the same firmware you can chose the work mode. It can work as a transmitter (master) or as receiver (slave).

Best regards,

Why didn't you use a variable for this?

wdomski commented 3 years ago

New version of software allows to change the Master/Slave operation. Please give it a try. Also the dev platform has changed to STM32 Nucleo L476RG board, so the switching is easier.

Hello! how and why to write the output mode pin if mode_pin is an input? that part I didnt understand.. HAL_GPIO_WritePin(MODE_GPIO_Port, MODE_Pin, GPIO_PIN_RESET);

I put 3v3 or gnd to select master or salve mode in mode pin, but the write pin I didint understand thank you!

You are right! It should be LED pin.
