From the User Manual in the GPIO/Analog inputs section, I see the following: GPIO Ch 0 = ADC 0 GPIO Ch 1 = ADC 1 GPIO Ch 2 = ADC 2 GPIO Ch 3 = ADC 3 GPIO Ch 4 [no analog] GPIO Ch 5 [no analog] GPIO Ch 6 = ADC 5 GPIO Ch 7 = ADC 6 It would have been easier for looping through to read the analog channels if the ADC channels were numbered from 0 to 5 instead of 0-3 and 5,6. Is the above correct? Does this mean that sending "adc read 4" will not return anything?
GPIO 8. So here is what I have found. Please let me know what I am doing wrong or confirm that the Numato User Manual is incorrect. I have a temperature sensor that is reading fine on the Numato device and confirmed with a digital multimeter. Now I want to hook up other sensors to the remaining ADC channels but need to understand the schema after IO5. Read the sensor voltage with a digital meter, get a reading of 0.78V. I connect the same sensor to: IO0, send a command adc read 0, get a reading of 0.78V. OK. IO1, send a command adc read 1, get a reading of 0.78V. OK. IO2, send a command adc read 2, get a reading of 0.78V. OK. IO3, send a command adc read 3, get a reading of 0.78V. OK. IO4 and IO5 according to the manual is not supposed to have analog. I do not get meaningful adc readings from these IOs. OK IO6, send command adc read 4 get a reading of 0.78V. (according to the manual IO6 is adc 5 so I did not expect this) IO6, send command adc read 5, get a reading of 0. (according to the manual IO6 is adc 5 so I did not expect this. I expected 0.78V) IO7, send command adc read 5, get a reading of 0.78V (according to manual IO7 is adc 6 so I did not expect this.) IO7, send command adc read 6, get a reading of 0.78V. OK (according to the manual IO7 is adc 6, so this is the expected result.) IO7, send command adc read 7, get a reading of 0.78V (huh? there is no adc 7) What is the correct adc send ? command when connected to IO7? Should the manual on Page 3, GPIO/Analog inputs, read as follows?: IO Ch 0 = ADC 0 IO Ch 1 = ADC 1 IO Ch 2 = ADC 2 IO Ch 3 = ADC 3 IO Ch 4 [no analog] IO Ch 5 [no analog] IO Ch 6 = ADC 4 ? IO Ch 7 = ADC 5 ? Someone please offer some insight, otherwise I am stuck using only IO0 though IO3. Thank you
Hi DMc, I had someone crosschecked the datasheet and the firmware and it turns out the datasheet is incorrect. The analog input channels are numbered 0 - 5. So it should be possible to access them easily in a loop. we will correct the datasheet as soon as possible. Also thanks for notifying us about this mistake. Thanks, Tom
