Arduino, Thermocouples, MAX31855K (vs MAX6675) and SPI – The Fine Points

It can’t be that hard to get a MAX31855K up and running … ↓↓↓ Complete description, time index and links below ↓↓↓ Or so you might think. But if you have one of those simpler Chinese modules you’re facing a challenge right out of the gate: it won’t work without modification. And if you have to 5V MCU, you’ll need some level shifting down to 3.3V. There’s a nice MAX31855 library available for Arduino, but you can also bit bang the SPI bus directly. Multiple slaves on the SPI bus are a must of course. But do you really need a MAX31855K or will a MAX6675 just do fine. 00:00 Intro – Arduino, MAX31855K and past MAX6675 videos 01:04 MAX31855K vs MAX6675 – datasheets, differences, similarities 07:53 Input filtering – strongly recommended, in fact required 09:33 5V operation – connecting the 3.3V MAX31855 to a 5V MCU 12:49 MAX31855 library – by Rob Tillaart, easy and lean 17:57 Bit banging – code for the MAX31855K with just the SPI library 29:08 Multiple MAX31855Ks – on the same SPI bus 31:47 Mixing 5V and 3.3V – devices on a SPI bus is complicated 32:58 5V compliant modules – they are not, at least not fully 35:06 Shorting things – and destroying MAX31855s 36:22 Wrap-up – verdict, link to code and bye Tutorials:    • Tutorials   Mini Mailbag: Breakout PCBs for HB100 Doppler Radar and MAX31855K Module    • Видео   Arduino, Thermocouples, MAX6675 and SPI – The Fine Points    • Arduino, Thermocouples, MAX6675 and SPI – ...   Faulty Chinese MAX31855K Modules: Fake Chips?
