GD32F303 + DSO 150 = :)
As said previously, the GD32F303 is close to the F103, with more ram (48kB), more flash (256 kB) and...a better ADC On the DSO shell/150, i swapped the STM32F103 with a GD32F303 and after some tuning here is the end result : Most of the code runs fine, only exception is rotary encoder i had to move to PB14/PB15. Probably the init code that is not correct. The GD32 has more dividers for the ADC, it means that when running at 96 Mhz, no need to duplicate/drop samples as we can find an exact frequency divider for the "fast" rates. The unit runs fine at 96 Mhz, including the screen. With the "zero wait state" nature of the GD32 (it uses ram), the unit is now almost ~ 2x faster ! We have enough horsepower to add a second channel, just saying... Some others features that are interesting to look at later : Scan mode : To sample continuously Hardware oversampling/ average : For free ! It is a cortex M4, it has some DSP style instructions So far i like...
