Hi daniel.
I am playing and cores the old programs to bring them to 0.4.0. First of all I noticed that (in my USB library, but perhaps also in /Pico /Stionim ->) the program fails:
../hardware/i2c.nim

proc stdinReadLine*(echoInput: bool = true): string =
  while true:
    let res = getcharTimeoutUs(100_000) #return -2 if empty buffer
    if res != PicoErrorTimeout.int: # --> if res >= 0 and PicoErrorTimeout.int:
      let character = res.char #non convert values < 0
      if character == '\r':
        echo ""
        break
      else:
        result.add(character)
        if echoInput:
          discard putcharRaw(character.cint)
          stdioFlush()

This is because (it seems) that "Gettimeoutus" if he has nothing written in the Buffer returns -2, and the conversion obviously fails. Give us a look!!

Second, I bought the RP 2350 to try it, I wondered if during the compilation (or I don't know when) to fill in for it, you have to put some flag somewhere!(I see that you added something for him)

for the monte is all! bye by Martin A.

I will definitely disturb you again

One thing that could perhaps be improved (as a lazy electronic) is the functions:

• i2cWriteBlockingNim
• i2cReadBlockingNim
  Making the following, modification, which for practical use is perhaps more "natural" and practical (after -> the suggested modification):

proc i2cWriteBlockingNim*(
    i2c: ptr I2cInst,
    address: I2cAddress, --> address: uint (o maybe Uint8)
    data: var openArray[uint8],
    noStop: bool = false
  ): int =
  ## Write bytes to I2C bus.
  ## If `noStop` is `true`, master retains control of the bus at the end of
  ## the transfer.
  result = i2c.writeBlocking(address, data[0].addr, data.len.uint, noStop) --> result = i2c.writeBlocking(address.I2cAddress, data[0].addr, data.len.uint, noStop)

p.s. Unfortunately with git I am not very good hindsight I would try to make a Commit (but I will try in case of examples)
