4/29/2023 0 Comments Arduino Set Serial Parity![]() ![]() To send and receive I used the basics tutorials like: if (Serial. ![]() So I start searching more about serial communication and found about start and stop bits and parity and start wondering if I'm sending and receiving data in the way the device expects. Using this function will set the remaining UART parameters to default values ( Data length 8, Parity bit 1, Number of Stop BitsNone ). The speed parameter is the baud rate that we want the UART to run. The device sends back a response like "CE 0F " with spaces in between. The easiest way to configure the Arduino’s UART is by using the function Serial.begin ( speed). Everything went fine.īut with the device itself it's not working. I've set the start and stop bit as ASCII characters put the data and CRC in between and simply Serial.write(data) I've setup two Arduino boards and both communicating this way. ![]() The device uses a request/response protocol, so the Arduino board must send the data in order to receive something. My problem is that the company that made the device a I need to communicate with told me the following:ġ) The data sent through serial have one start and stop bit and is the hex "7E".Ģ) On the end of the message is appended a CRC hash I need to communicate with a device using Arduino through RS232, I have everything setup and working. ![]()
