STM32 VGA Output - don't understand why lines are jagged
is my code:
// interrupt handlers
void EndVBackPorch();
void ShockAbsorber();
volatile uint8 *GPIO_ODR;
volatile int vflag = 0; /* When 1, can draw on the screen */
void setup()
{
pinMode(PB6, PWM … ); // VSync
pinMode(PB0, PWM); // HSync
// PA0..PA5 set to OUTPUT with max speed 50 MHz
GPIOA->regs->CRL = 0x88333333;
GPIO_ODR = (volatile uint8_t *)&GPIOA->regs->ODR;
// 640 x 480 @ 60 Hz …
