(SOLVED) AtMega32a + Nrf24L01+ Nrf is so poorly documented need help.
Hi, I use the NRF 24L01+ modules for half a year now without trouble (once I got the basics working using the datasheet). I remember it took me a couple of days before I got it...

Proper multiple USART usage - ATmega2560
Are you aware that 16MHz and 115k2 does not go well together ? I read in your first entry "New code use only hardware USARTs". Could it be the old code used software UARTS which...

A new method for measuring lots of resistors using a minimal amount of cables
Thanks for documenting and sharing. When using it for measuring thermistors, you could also add an extra option : bipolar measurement. You can use this to eliminate seebeck...

OS270 Programmable Resistor Bank
Answer to my own question, in case someone is looking for the same. I ordered the device and it works great. It works only on batteries, so I was afraid the batteries would go...

OS270 Programmable Resistor Bank
I am designing miniature precision 17-channel thermistor measurement device. I now use manual resistor decade banks but for next measurements I need to do much testing over the...

NTC self-heating or something else
Sorry, it is not clear to me what you describe here. What to you mean by 'constant resistor' ? Is this the series resistor ? You can also lower your supply voltage to lower self-...

NTC self-heating or something else
Do you have an oscilloscope ? In that case its pretty easy to see how much selfheating you have by connecting the NTC and 10k series resistor to the supply and see how much the...
