Ugh #BL602 #ST7789 Fallen Lorry ... While cleaning up the code 🤔

#PineCone #BL602 @PINE64 works great with #LVGL and #ST7789 yay! 🎉 Wasn't so hard ... Now lemme write everything down

https://github.com/lupyuen/bl_iot_sdk/tree/st7789/customer_app/sdk_app_st7789

Aha our #BL602 SPI Receive Buffer is too small for #LVGL! 😱 ... Rightfully we don't need an SPI Receive Buffer ... But the SPI HAL only supports SPI Transfers with Transmit AND Receive so 🤷🏻‍♂️ ... Let's increase the SPI Receive Buffer anyway

https://github.com/lupyuen/bl_iot_sdk/blob/st7789/customer_app/sdk_app_st7789/sdk_app_st7789/display.c#L323-L354

Yep #LVGL runs on #BL602 ... But it hangs when rendering to #ST7789 ... Let's find out why 🤔

How I Build, Flash and Run #BL602 Firmware on macOS ... Yep I need to flip the #PineCone Jumper every time I do this 🤔

https://github.com/lupyuen/bl_iot_sdk/blob/st7789/customer_app/sdk_app_st7789/run.sh

#LVGL builds OK on #BL602 with #ST7789 Display yay! Let's test LVGL on BL602...

#BL602 Makefiles look complicated ... Let's add #LVGL here for now

I remember the Lorry Joke ... We were rendering #LVGL on #PineTime's ST7789 ... And the graphics were rotated 90 degrees.

That's why we called it "Fallen Lorry" 😂

Then we laughed that only folks in the British Commonwealth understand the word "Lorry" 😂
