You told that some mainboards are working "some of them are working and some are not". Is it possible to have couple of those which are working or refund? As I mentioned earlier I have two faulty CrowPanel 5 inch and one CrowPanel 7 inch w…

(Quote) What are you going to do when the controller you are using does not work according to specification and causes problems for your customers?

This is bad news. I have purchased two CrowPanel 5 inch and one CrowPanel 7 inch boards for my project. Now they are apparently unsuitable for my needs. Is there an alternative board available that would have a working connection or do all Elecrow b…

It is 29th of May and I am still waiting for your response.

(Quote) When I test OneWire using pin38 the connector I am using is GPIO_D, of course.

This my CrowPanel 5 inch.

****This is simple test code I have used. : ** #include <OneWire.h>#include <DallasTemperature.h>// OneWire väylä GPIO20#define ONE_WIRE_BUS 20 // in order to test IO38 as OneWire I change this// Luo OneWire- ja DallasTemper…

What is the difference between pin 20 and pin 38? OneWire connection works if I use pin 20 (I2C). When I configure OneWire to use pin 38 and move the same connector to GPIO-D, no sensors are found. The same OneWire-DS18b20 connection is used in both…

I have already done that (using IO38 on GPIO-D connector)! it doesn't work. Do not find any sensors.

I do have pullup (4.7K) resistor between DQ and 3.3 V. I cannot have any values from OneWire devices if I am using pin38 GPIO-D connector. If I am using pin20 as OneWire (I2C connector) I get correct values (but touch do not work of course). It seem…
