Lunar New Year #Durian 🤤

Ugh #BL602 is disrupting the two SPI Transfers ... By setting the Chip Enable Pin high ... Let's control Chip Enable Pin ourselves with GPIO

LA2016 Logic Analyser comes in this beautiful inspirational box ... "Embedded Development Kit: Innovative concept, win-win cooperation"

Nope #BL602 still receiving garbage from BME280 ... Let's do the #SPI Logic Analyser!

Let's try 2 #BL602 SPI Transfers instead of 1 ... First SPI Transfer transmits Register ID ... Second SPI Transfer receives the result from BME280

#BL602 SPI Data Pins seem to be flipped ... Based on SPI data sniffed by Logic Analyser 🤔

#PineCone #BL602 @ThePine64 connected to BME280 and LA2016 Logic Analyser ... Let's sniff the SPI Bus and find out what's wrong!

“The Cantonese word for [ non-starch ], sung, 餸, is so pervasive that “the word for ‘grocery shopping’ in Cantonese is mai [sung], or ‘buying sung,’ since the starch is a staple that would already be in the house.”

Logic Analyser captures SPI Data between #BusPirate and #BME280 ... So cool! 🤩 Now to capture #BL602 + BME280 and compare

Logic Analyser connected to #BusPirate and #BME280 ... Hope this works 🤔

...But now we get pretty Blue and Red Lights on #PineCone #BL602! 🤩 Time to do the SPI Protocol Analyser ... My first time ever!

Nope Recommended SPI Pins for #PineCone #BL602 also don't work
