Implementing more messages and getting the startup sequence right …
↓↓↓ Complete description, time index and links below ↓↓↓
Last time we’ve established the basic library structure based on C++ unions and got the MLX90363 up and running using no operation messages (link below). However, during power on startups our library threw some errors. It’s time to fix that.
We’ll first implement three more messages to eliminate the errors. Then we’ll come up with a working reboot sequence for the MLX90363, to get it reliably into a defined state. For reasons that will become clear, this will include standby messages.
00:00 Intro – implementing more OpCodes to avoid errors
01:31 OpCodes – we might see after power on
03:08 Interleave – of MOSI commands and MISO responses
05:23 Ready message – first MISO messages after a reset
06:40 Error message – slave throwing some kind of error
07:48 NTT message – slave has nothing to transmit (NTT)
09:18 Code 1 – ready, error and NTT MISO messages
17:27 Test 1 – no library error, but inconsistent behavior
20:04 Reboot message – resetting the slave
21:50 Code 2 – reboot message and reboot during begin()
26:05 Test 2 – consistent startup behavior, but it’s an error
27:18 Standby message – putting the slave into standby
29:00 Startup sequence – the right messages in order
33:55 Code 3 – standby message and extended begin()
39:02 Test 3 – consistent startup behavior, no error
40:13 Wrap-up – getting magnetic data is next, bye
