Hi everybody,
I'm actually sending the data 0x5B at 115200bps on my serial port so that I produce a 38.4kHz waveform during a 78µs writing period, so I control the sending of a signal on Tx on a smaller timebase than the minimum 1ms of Windows. The problem is that I'd like to have 38.4kHz or nothing on this period and even sending 0x00, the start bit create a signal (at 12.5kHz, 1 bit on 8). As my knowledge on the serial port is limited, I'd like to know if there's a way to avoid this, maybe by using another signal (DTR for example) to pull down the Tx when I want to avoid writing.
I don't know if it's the simplest way to manage this so I wanted to talk about it before starting my development.
Thank you in advance
Bim
