Yep #PineCone #BL602 @ThePine64 runs on Batteries ... Should use this to measure Power Consumption 🤔

Good Morning #PineCone #BL602 @ThePine64 ... Oops wrong logo

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

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