Touch Screen for #PineDio Stack #BL604 feels laggy on Apache #NuttX RTOS right now ... 2 things we can fix: 1️⃣ Increase SPI Frequency 2️⃣ Switch to SPI DMA eventually

#NuttX Driver for #PineDio Stack #BL602's Touch Panel responds correctly to touch! 🎉 The touched coordinates are rotated sideways ... But we can fix that later in the ST7789 Display

Here's how our #NuttX Driver reads the Touch Data on #PineDio Stack #BL604

https://github.com/lupyuen/cst816s-nuttx#read-touch-data

Apache #NuttX RTOS has a standard data format for Touch Input ... Let's implement this for #PineDio Stack #BL604
