#NuttX Apps can't call the SPI Driver directly ... Here's why

https://lupyuen.github.io/articles/spi2?3#spi-test-app-and-driver

To test the #NuttX SPI Functions, we create an App and a Device Driver

SPI Pins for ST7789 Display on the redesigned #PineDio Stack #BL604 ... Will verify this with the new schematic ... Why is LoRa so much easier to test than ST7789? 😭

Trying to Bit Bang the ST7789 Display on the redesigned #PineDio Stack #BL604 ... Nope still not working, will try harder 🤔

Voxel Diagrams 🤔

Redesigned #PineDio Stack BL604 works great with #LoRaWAN and #TheThingsNetwork! 🎉 ... Though we're using an NB-IoT Antenna 😂

We run this command to transmit #PineDio Stack's Internal Temperature to The Things Network over #LoRaWAN

MagicaVoxel Voxel Editor looks interesting 🤔

Thank you Qoto Mastodon ... Lots more content coming up! 😀

Let's test the redesigned #PineDio Stack #BL604 with our #LoRaWAN Firmware ... And send some Sensor Data to The Things Network!
