Speed of uart

What's the fastest i can make uart go? What's the biggest number i can enter for baudrate? I try 9600 things work. I move up to 112500 still ok. From a raspberry pi header file i find a rate 1125000 things still seem ok. When i try another number from that header like 16000000 my data transfer still...

Re: logging data on SD at constant frequency

I've tried a few things and a 2 pyboard solution can only achieve 4kHz over uart. With one sensor being logged along with the time in micro seconds and a check digit

Re: PyBoard with Wifi and Screen

The upcoming pyboard-D has built in wifi, it should be available later this week maybe next.
There should be a touch screen skin for it in the near but not too distant future

Re: pyboard 1.1, sd card, and ENODEV error

ENODEV is correct for no SCL wire. Was it reporting an acceptable line number?

Re: pyboard 1.1, sd card, and ENODEV error

Does i2c.scan() find this device?
