#BL602 SPI talking to #ST7789 at 4 MHz ... Works perfectly if the SPI Transmit Buffer is located in RAM ... Transmitting from Flash ROM might be too slow for 4 MHz DMA

https://github.com/lupyuen/bl_iot_sdk/blob/st7789/customer_app/sdk_app_st7789/sdk_app_st7789/display.c#L79-L194

Here's how we set SPI Timeout in #BL602 SPI HAL ... Default is to Wait Forever, which can cause problems with 4 MHz SPI

https://github.com/lupyuen/bl_iot_sdk/blob/st7789/components/hal_drv/bl602_hal/hal_spi.c#L346-L350

#BL602 SPI 4 MHz works with #ST7789 ... But only when we set the SPI Timeout 🤔

#LVGL on #BL602 is surprisingly pleasant ... Because we can see ALL the debug messages 👍

#PineCone #BL602 @PINE64 connected to #ST7789 at 2 MHz SPI with DMA ... 4 MHz SPI will hang sometimes 🤔

#BL602 IoT SDK hides "assert()" messages by default ... Here's how we show Assertion Failures

How we connect #PineCone #BL602 @PINE64 to #ST7789 SPI Display

I followed my dreams and got demoted to Software Developer

Any #BL602 Pin may be configured for PWM ... Very useful for dimming the ST7789 Backlight

https://github.com/lupyuen/bl_iot_sdk/blob/st7789/customer_app/sdk_app_st7789/sdk_app_st7789/display.c#L320-L332

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

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

How we run a #BL602 Command at startup ... Useful for #IoT Gadgets and photoshoots
