We have hosted the application gd32f330 lib in order to run this application in our online workstations with Wine or directly.

Quick description about gd32f330 lib:

GigaDevice GD32F330 startup code/peripheral library.

Use:

#define F_CPU 84000000
#include "gd32f330f8.h"

flash_lat(0); // latency=0

// bus.prescalers
ahb_div(AHB_DIV_1);
apb1_div(APB1_DIV_1);
apb2_div(APB2_DIV_1);

hxtal_on(1); // HXTAL @ 8M
pll_on(1,1, 21); // PLL @ 84M = 8M / 2 x 21
sysclk_sel(SYSCLK_PLL); // SysCLK=PLL

// peripheral clocks
ahb_on(AHB_GPIOA | AHB_CRC);
apb1_on(APB1_TIM2 | APB1_TIM5);
apb2_on(APB2_ADC | APB2_TIM0);

// GPIO
pin_mo(GPIOA,1, MO_AF); // mode
pin_ot(GPIOA,1, OT_PP); // o.type
pin_os(GPIOA,1, OS_10M); // o.speed
pin_af(GPIOA,1, 4); // AF mode

// ADC
adc_on(ADC_RES_12B, ADC_AL_RIGHT, 0); // enable
adc_cal(); // calibrate
adc_iref_on(1); // Vref/Tref on
adc_trig(1, ADC_TRIG_SOFT); // soft trigger

adc_stime(17,ADC_239_5); // s.time
adc_chn(17); // Vref channel

adc_start(1); // start

while(!adc_ready()); // wait

int vcc = adc_vcc(adc_rd(), 1200); // measure VCC, mV.
