What happens if #BL602 #NuttX writes to an I2C Register without reading it afterwards? The I2C Write gets truncated or zeroed 🤔

https://github.com/lupyuen/rust-i2c-nuttx#fix-i2c-write

#BL602 #NuttX now writes correctly to I2C Registers! 🎉 There's an extra I2C Read at the end, but it should be harmless

https://github.com/lupyuen/rust-i2c-nuttx#fix-i2c-write

I2C Write on #BL602 #NuttX works ONLY when we do an I2C Read AFTER the I2C Write ... So quirky! 🤔

https://github.com/lupyuen/rust-i2c-nuttx#fix-i2c-write

Trying all combinations of I2C Read / Write / Sub Address ... Till we find one that works on #BL602 #NuttX 👍
