 Had kinda hoped that somebody out there might have written up a guide on how to use this board with the BASCOM-8051 BASIC compiler but a decent 'howto' note couldn't be found. Had kinda hoped that somebody out there might have written up a guide on how to use this board with the BASCOM-8051 BASIC compiler but a decent 'howto' note couldn't be found.
  
-So, a few notes on how this might work. As things stand (Sept 2019), some parts are ordered and a bit of research is started. As and when the parts arrive and can be played with, notes will be added here. N.B. To date, I've not even been able to program the device!+So, a few notes on how this might work.

 The chip is a 20 pin surface mount part. Manufacturer datasheet (a 273 page .pdf) can be found [[https://datasheet.lcsc.com/szlcsc/Nuvoton-Tech-N76E003AT20_C82751.pdf|here]]. It's generally a lot easier to buy a dev board with this device already in place than to manhandle the bare part. The chip is a 20 pin surface mount part.

 +Asserted that my dev board hasn't been setup with a serial bootloader, so I'll have to await the arrival of the 'link' programmer before a lot more can be done. The programmer is a 3-wire affair.

 This chip has both user program and bootloader areas. It should be possible to use the Nuvoton supplied serial bootloader to allow the board to be programmed via a standard USB to serial port adaptor. This chip has both user program and bootloader areas.

 +  * A small enclosure will need to be milled to hold this part.
