RS485 ModBus tiny multi-sensor module
Would you be able to implement the scd30 sensor? This is a very cool project. Nice work.
Hi cbalint13, is there a way burn/flash the roms (boot.hex, boot.epp, main.hex) of tinnymodbus via the Arduino IDE? If so - what options do we have to chose for an...
Dear Sir ! Your project is simple and beautiful, my congratulations ! I want to ask if you will have support from other I2C sensors ? I have a small...
Thanks for a great project! I would really like to se this Modbus bootloader work for Uno / Mega on a UART. Is this possible ?
Dear @cbalint13 , really great project!! I searched a quiet while and only found this, which is near to my requirements. The 1wire function is really great already. Could you...
Hi Cristian, Readings from a USB-RS485 Adapter to 4 daisy-chained RS485-Sensors are stable, but when i use a custom ESP32 Modul i sometimes have read errors. That is why i...
Hi Christian Great project. Thanks for sharing I don't know if this project is dead or frozen, but it can be very useful to get an modbus error code when...
Hello, I built up two of the tinnymodbus. Flashing over modbus works fine. I can also read out the internal voltage (0x03 0x0003), the internal temperature is too high. I...
Hi! It is not working stable because built-in oscillator cannot provide the required frequency accuracy. Only one of the four chips that I tried worked. Quartz resonator needed. But it...
Hello, Very nice and interesting project. I have build me the curcuit on a tab. My question. I'm interested in i2c devices pcf8574., mcp4724 and ads1115, Have you a resolution?...
