t圎22pin and r圎22pin is the pin to connect to UART and they are mandatory.LoRa_E22(byte t圎22pin, byte r圎22pin, byte auxPin, byte m0Pin, byte m1Pin, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600) įirst set of constructor are create to delegate the manage of Serial and other pins to the library. LoRa_E22(byte t圎22pin, byte r圎22pin, byte auxPin, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600) LoRa_E22(byte t圎22pin, byte r圎22pin, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600) When transmitting data can be used to wake up external MCU and return HIGH on data transfer finish. Fully connected schemaĪs I already say It’s not important to connect all pin to the output of microcontroller, you can put M0 and M1 pins to HIGH or LOW to get desidered configuration, and if you don’t connect AUX the library set a reasonable delay to be sure that the operation is complete ( If you have trouble like freeze device, you must put a pull-up 4.7k resistor or better connect to the device. There are some pins that can be use in a static way, but If you connect It to the microcontroller and configure they in the library you gain in performance and you can control all mode via software, but we are going to explain better next. Users can access the register through the serial port to control the working state of the module UART and wireless channel are open, transparent transmission is on (Supports configuration over air via special command)Ĭan be defined as WOR transmitter and WOR receiver Può essere configurato come uscita open-drain o output push-pull (è consentito non metterlo a terra, ma se hai problemi, ad esempio ti si freeze il dispositivo è preferibile mettere una restistenza di pull-up da 4.7k o meglio collegarlo al dispositivo).Īs you can see you can set various modes via M0 and M1 pins. Durante la procedura di inizializzazione di autocontrollo, il pin emette una bassa tensione. Per indicare lo stato di funzionamento del modulo e riattivare l’MCU esterno. Can be configured as open-drain or push-pull output TTL UART outputs, connects to external RXD (MCU, PC) inputpin. Can be configured as open-drain or pull-up input. TTL UART inputs, connects to external (MCU, PC) TXD outputpin.
