I have modified (hacked if you like) the casing of the DSO203 to add a small female header to be able to externally access the serial port at CN7 in the DSO203 schematic. An angled 6 pin female 2mm header was used for this modification.
The header with the 2 to 2.5mm pinout conversion header.
The naked header.
I hope to be able to make some sort of docking station for the DSO quad with a few rotary encoders and some buttons, for easy access at home and still keeping the device portable. But by checking the software I see that the SYS firmware does not have any serial port functions. As there is no GCC port of the SYS part of the firmware it is a bit harder than I expected to implement this myself. I don’t know why but I find it quite hard to add STM32 libraries to the build. Anybody willing to help?
Any other functions a serial port could be useful for? Implementing a small terminal or serial port monitor maybe.
