I am using the Arduino Pro Mini 3.3V / 8MHz for a project in which I need to transmit some data through the TX pin.
The thing is that when acceding to the transmitted data with the oscilloscope, the data does not correspond at all and also the oscillo is reporting some errors in some of the bytes.
Also, I am using a 2400 Hz baud rate, that is also used when uploading the code since this Arduino version has only one UART port. Could somebody verify if the problem may be on this baud rate? I was thinking that perhaps this version doesn't admit such a low frequency, or maybe neither uploading the code like that.
Thank you in advanced!
