Hi Klaus and Susan,
Many thanks for your help. Still working on the full code. Here it is so far.
The DHT sensor and also the interrupt switches are not attached. the pads are not populated at the moment.
The same code when the rpi pico is out of the PCB socket, works super well. I see the...
Hi, I tried very basic samples of LED blinking and also UART sending from RPI PICO W. For example this one:
from machine import Pin, Timer
led_onboard = Pin("LED", Pin.OUT)
def blink(timer):
led_onboard.toggle()
Timer().init(freq=2.5, mode=Timer.PERIODIC, callback=blink)
It hangs with...
Thanks for explanation.
I tested M5, it does work well.
I was confused how come I am able to send serial data out from microcontroller to an RS485 device with DI pin not connected to Tx of microcontroller.
Hi,
I want to build a PCB with RPI pico that can read devices over RS485.
I found the official schematic of RS485-TTL converter of M5.
Here in the official schematic (https://docs.m5stack.com/en/unit/rs485), the TX from microcontroller is connected to Enable pins, DE and RE. The DI of the...
Hi,
I designed this schematic to read RS485 device. It works for 10-20 seconds and then hangs.
I have tried it also with a simple LED blinking programming, not reading RS485, and it still hangs.
The T&H sensor is not populated at the moment.
Any suggestions what am I doing wrong?
thank you
