RS485 Arduino INO

ok thanks

Hi I have a ItsyBitsy M0 Express. I want to connect a RS485 Halfduplex with just the 2 wires A and B. I have connected a converter wich makes out of the differntial signal of the AB RX/TX. I have just left the MISO and MOSI pins. The connected part just sends 2 bytes after it received 2 bytes from ItsyBitsy, can you send me just such an INO code? Let me know how much it costs. Thanks Franz

Hello. I have a experience for arduino communication. the RS485 is serial communication. the important is control for select RX/TX. how do you connect the converter? and what is MOSI and MISO left? Regards.

Hi, can you send me your wiring diagram? I guess the problem with RS485 transciever is it contain control pin to set wether it will be used as sender / receiver. I have used RS485 for several project, so I know it's co Plus

HI, I think you can use a basic test I've used with RS 232, RS 485 should "just" change the physical layer, not the logic. The software is very easy, I cannot bid for less because minimum bid is limited by freela Plus

Hi you should connect #0 and #1 pin for serial Rx and Tx "SCK/MOSI/MISO - These are the hardware SPI pins" also you connect the rs485 converter de/re pin to gpio output to set direction

hello dear i think you have to use serial port of arduino not the spi, also do you use max485 as a converter AB/RS232 ? finally you can find many exemple in arduino ide select : file > exemples thanks aymen
