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 😂

https://github.com/lupyuen/bl_iot_sdk/tree/pinedio2/customer_app/pinedio_lorawan

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

MagicaVoxel Voxel Editor looks interesting 🤔

Here are the updated SPI Pins for #LoRa SX1262 on the redesigned #PineDio Stack BL604

https://github.com/lupyuen/lora-sx1262/blob/pinedio2/include/sx126x-board.h#L35-L49

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!

New condensed font by VSCode 😂

Our #NuttX App runs OK on PineDio Stack BL604 with onboard SX1262! 🎉

Here are the #NuttX Pin Definitions for PineDio Stack BL604 with onboard SX1262 ... As derived from the schematic

https://github.com/lupyuen/incubator-nuttx/blob/pinedio/boards/risc-v/bl602/bl602evb/include/board.h#L42-L95

Here's how Semtech SX1262 is wired onboard #PineDio Stack #BL604 ... Let's update the Pin Definitions in NuttX

Will #NuttX run on #Pine64's PineDio Stack BL604 with onboard Semtech SX1262? Let's find out!

https://lupyuen.github.io/articles/pinedio

Our #NuttX App now reads the SX1262 Register correctly! 🎉

BL602 vs ESP32 🤔

For #NuttX on #BL602, we use SPI Mode 1 instead of Mode 0 ... To work around the SPI Mode Quirk

https://github.com/lupyuen/incubator-nuttx/blob/spi_test/drivers/rf/spi_test_driver.c#L51-L57

Let's use an NB-IoT Antenna ... As the #LoRa Antenna for #PineDio Stack BL604 @PINE64 ... For now

https://lupyuen.github.io/articles/pinedio

#BL602 has an SPI Quirk ... We must use SPI Mode 1 instead of Mode 0 ... Let's fix this in #NuttX

https://lupyuen.github.io/articles/spi#spi-phase-looks-sus

Our #NuttX App reads an SX1262 Register ... But it returns garbage! There's a workaround for this #BL602 SPI Quirk
