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. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. (autopromotion^)) You want to connect rs-485 to arduino, have some 485 bus dri Lisää

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 Lisää

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 Lisää

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
