Does anyone have any example code using the 4-20ma current loop transmitter with RaspberryPI?
I do not find any reference material for the device control codes anywhere. I am a newby, so sorting through what seem to be unrelated documents has been frustrating, to say the least!
I am trying to use the PR33-26, 1-channel 4-20mA current loop transmitter I2C mini module with PR2-1 I2C shield for Raspberry PI on a Pi3+. The tranmitter shows up at 0x60 as expected, but I do not seem to be able to generate current. I am uncertain of the address to use for reg_write_dac in my command:
bus.write_i2c_block_data(0x60, reg_write_dac, answer)
Any help will be appreciated.
