  • when I connect to the RPI3 - blink 4times, and thats all, no blinks. When I connect to the heating controller (on atmega32) blink 4 times and blink all times every ~1s. when it check the 1-wire bus( on controller) blink faster. "What happens if you connect only the BME-1-Wire-Slave?" nothing. devices not seeing. "....Can you connect the 1-Wire Devices direct to the PIO-Pin 4?" yyy attiny has 5v - rpi work 3.3v directly not , I do not think so.

  • Hi, RoBue half success. When I connect power to the converter, diode blink x4. Thats means is recognized, correct me if I think wrong. But, converter is not visible in RPI3. My devices are connected to the rpi by DS2480 (see pic) and this work wery well. connected devices : 16b counter (ds2423 over attiny 25); ds18b20, and when connect the converter to the RPI3 all 1-wire devices connected to the RPI3 has gone. Do not see any devices. bascomforum.de/index.php?attac…568e9f3340a2ef01ea9e4ccef add …

  • Thank you for your help and patience Unfortunately I am going on a business trip and I will not be able to take care of it. We will return to this after 20.08 best regards

  • ehh, not work, after changes lockbits the led blinks faster Nothing changed the purchase of a new attiny. Maybe this is a new/old/another version of bme280 and is not properly detected. My module looks different from yours (see attach). Zitat von RoBue: „If you use UART you need an adapter, for example DS2480 or DS2480B an other drivers. “ yes, I use UART with adapter DS2480 and work properly. To the adapter I have connected counter ds2423 (emulation on attiny 25), ds18b20. work. best regards

  • Hi I see the light in the tunnel. When I back to home check this. Yes, I prepare the PCB. To build the PCB I used what I had. Is not perfect. I use LM1117, you can replace lm1117 -> lm1117 3.3v, then you need to remove the resistors R2 i R6 I can't connect directy this, becouse attiny have 5v rpi 3,3v. I use level converter and connetc bme280 -> attiny85 ->1-wire -> rs232 -> rpi uart. best regards

  • hi, Zitat von RoBue: „Are you sure you have a BME (and not a BMP)? “ yes, Im sure this is GY-BME280 V3.3 The sensor measures the pressure, temp, hum. Zitat von RoBue: „Look also wether your system is running with 8Mhz (look at lock- and fusebits of your ATtiny -> engbedded.com/fusecalc ) “ yes, 8Mhz and fusebity 0x62 0xDF 0xFF i not changes becouse I dont know Zitat von RoBue: „If it does't find the sensor, it ends in a loop with blinking LED continuously. “ And here is the problem because I do …

  • Hi RoBue, thank for you reply, Unfortunately it does not work When connected the module to the ATTINY ,LED blink continuously, and RPI not recognized. 4x led blink on your old program. I downloaded from this site , but this version also not work. Question: pin1 must be connected to the pin8? (it does not matter, connected or not does not work) So, could you check the voltage level on the pin 6 , i'm is always low (module not connected to the converter, computer ). i think it works for you, how a…

  • Zitat von RoBue: „5. 1-Wire-Slaves mit BMP085/180 und BME280 “ Hi Robue I have some trouble with bme280. I prepare schematic (see attach), use yours program (I do not know about programming), but doesn't work, and not see on my RPI3. LED blinks continuously, and I think my module not recognize properly . Module work, because I connect to rpi3 and in terminal i see value. Pls check the schema, or maybe lockbit is wrong or something . All device 1-wire are connected to the converter 1-w->rs232 and…
