swap (or change) uart pins on pyboard

Hi all Is it possible to change or specify the pins used by the pyboard for RX and TX for a UART port? For example, x9 is used as tx and x10 as RX, per default for UART(1). But I'd like to swap this around. It seems that the machine module in micropython might allow for this. But I could not get thi...

sending data over wifi/adc sample rate

These might be naive questions. However, I would like to be sure before buying one of the pyboard-Ds. Q1: Can I use the wifi connection to send data (collected using the ADC pins) to another computer? Or stated differently, can I read data from the pyboard from a computer, using the wifi? I have sea...

Version control

I have a general question about the workflow for working with the pyboard: how do you go about version control? I am working on a project which involves multiple files. I want to use version control to keep track of the project. However, I can't find a good way of doing this. Here is what I tried: P...

How to use DAC mode normal?

I am trying to output a block wave of given frequency and duration on pin x6 (DAC 2). I can use the following to get output on pin x6. However, this seems to run forever. dac.write_timed(buffer, 20, mode=DAC.CIRCULAR) I was hoping I could use the following code to send a predefined signal (in buffer...

How many adc pins can I use?

The documentation says the pyboard has 3x12 bit adc. Does this mean I can only use up to 3 pins to get analog input on the pyboard (instead of 16)?

Sending large array of numbers to host computer

I use the Pyboard's ADC's to fill up an array with 7500 unsigned short integers. Now I want to send the data to the host computer. At the side of the Pyboard I'm using port = pyb.USB_VCP() port.send(data) or port = pyb.USB_VCP() port.write(data) I am having (at least two problems): 1) the data gets ...
