'/' works for me, too.

Ok, it was of course my fault. I had messed up the configuration and with it the assignment of the coros.
Now everything works.

Ok, switched the topic to 'qwe' and found out, that, opposed to what I wrote before, the subscription does not work. Code: def callback(topic, msg, retained): print((topic, msg, retained)) async def conn_han(client): print('subscribing...') await client.subscribe('qwe', 1) async def main(client): aw...

Hi, I'm running this code: def callback(topic, msg, retained): print((topic, msg, retained)) async def conn_han(client): await client.subscribe('test/topic', 1) async def main(client): await client.connect() n = 0 while True: await asyncio.sleep(5) print('publish', n) # If WiFi is down the following...

Thanks for the hint but we ran some tests with the SPI version and it showed not difference in stability to the normal driver. So there is no gain for the loss of one pin. But I have to admit that I did read the data sheet of the HX711 wrongly. I thought the clock signal must have a maximum length o...

Hmm, so I guess it is not possible?
That is too bad. RMT pulses are quite stable and could be used for creating the clock signal for a HX711 driver. That would be a great improvement over the current bit banging. But without knowing the state you can not synchronize with the data signal.

If I use RMT to generate a pulse on a pin is there a way to know the current state of the pin? Ideally something like Pin.IRQ_FALLING that triggers a callback. I tried to use this but it fails. Most llikely because you can't have RMT and Pin on the same pin at the same time. from utime import sleep_...

Sorry to dig this up.
I failed to find any documentation on this part:

GPIO_OUT = ptr32(0x60000300) # GPIO base register
for i in range(100):
GPIO_OUT[1] = 0x10 # set bit 4
GPIO_OUT[2] = 0x10 # clear bit 4

Is there documentation or is it obsolete by now?

Thanks - I'll look into it.

These are ADC for bridges, mostly used for scales.

Has anyone successfully communicated with one of these?

Apart from this:

I came up empty handed wrt to python.

Thanks
