* Major changes in Chopstx 1.9
Released 2018-05-09
** GD32F103 support
GD32F103 is an alternative implementation of STM32F103 by Giga Device,
which can run at 96MHz.
** Minor USB driver fix for STM32F103
BTABLE setting should be done for initialization, not for USB RESET.
** Minor ADC driver change for GD32F103
ADC on GD32F103 is another implementation and its behavior is somewhat
different. It requires waits after enabling. So, we use continuous
samping. Still, we observe enough noise (> 4.7 bit/byte) for each ADC
sampling.
