I bought the following version of HX711 module.
Connection to Arduino VCC -> 5V GND -> GND SCK/TX -> GPIO 6 DT/RX -> GPIO 7
However, it doesn't work. I have tried different libraries and even different boards but there seems to be communication problem with the module. I assume it has something to do with the mcu chip and the jumper connections J3 & j4. The mcu chip is STC 8F1k08.
There are a lot of tutorials regarding HX711 modules but I couldn't find any info about this particular board with an MCU. There is some info (chinese translation) on the sellers page but doesn't say anything about the jumper config. Product page
I tried to find any relevant info in the MCU datasheet but with my limited knowledge of MCUs it didn't help much. Apparently it's possible to communicate through Serial & I2C with this MCU.
So can someone please help me solve the communication issue?
