Can someone please detail the steps to change the SPS rate from 10 to 80. I have a ESP8266 and HX711 setup and I need to have a faster data rate between the two. The datasheet mentions Rate = 0 for SPS of 10 and Rate = 1 for SPS of 80. Does this mean this can be manipulated from code base or does it require desoldering of the pin 15 and shorting to pin 16? If desoldering is required, I have failed, can someone recommend another method?
Hello @gaurang84!
Does this mean this can be manipulated from code or does it require desoldering of the pin 15 and shorting to pin 16?
The second option, you have to modify the chip. If you look at the datasheet you will find that you have to use the internal oscillator so you have to connect pin 14 (XI) to ground and to select the 80SPS rate you have to connect pin 15 to VCC (pin 1 or 16) (RATE = 1 = DVDD = VCC). To achieve this you have to desolder pin 15 and connect it to high, although some HX711 boards have a jumper you close with solder and in others you have to cut a trace.
So if you have a breakout board, I suggest looking at the schematic or asking the manufacturer of the board.
