anomaly using i2c api

I think I have discovered a small anomaly with the pyb.I2c api. I have a chip on the bus (SC16IS7X i2c uart), that has a soft reset bit, and normally setting this resets the chip and thus causes an i2c fault. This is fine and is the behaviour I see on Linux etc BUT with the pyb i2c interface, I don'...

Re: I2C/SPI gateway for a PC

actually I think I can do this by just sending the raw python commands to the repl and interpreting the results, much easier than writing a protocol, and it will work on a bare bone pyb ie if the pc wants to perform a i2c read then it sends "i2c.mem_read(x,y)" then something like... l = port.readlin...

Re: I2C/SPI gateway for a PC

oh also it means I can write code for the pyb on the pc, and have some debug capability.
Im new to this presumably there is no debugability on the pyb

Re: I2C/SPI gateway for a PC

Hi Thanks for the response, yeh just like bus pirate,
ok not sure how to steal the port from the repl tho
I tried a quick (boot.py)

Code: Select all

import sys
while True:
    s = sys.stdin.readline().rtrim()
	sys.stdout.print(s)
but the repl still is in control. Im missing something obvious.... :)

I2C/SPI gateway for a PC

I have an idea for my first project. :shock: Basically I want to provide a uart protocol, so a pc app can send commands and the pyb can then perform the operations eg I2C SPI ADC et al. This means I can develop an app in vs2015 using the brilliant python addin during development phase. Q Has anyone ...

Re: New users post approval

Anyway I have ordered my board and look forward to playing, but would like to say I am very impressed with the web site and the documentation so far....
The journey begins...... :D
