stm32f407 GPIO
no vote
This example describes how to toggle the GPIO pins connected on AHB bus.
PD12, PD13, PD14 and PD15 (configured in output pushpull mode) toggles in a forever loop.
- Set PD12, PD13, PD14 and PD15 by setting corresponding bits in BSRRL register
- Reset PD12, PD13, PD14 and PD15 by setting corresponding bits in BSRRH register

STM32F407 SysTick
no vote
This example shows how to configure the SysTick to generate a time base equal to
1 ms. The system clock is set to 168 MHz, the SysTick is clocked by the AHB clock
(HCLK).

LPC1788 RTC
no vote
This example describes how to calibrate RTC
/* In this example:
* Suppose that the RTC need periodically adjust after each 5 second.
* And the time counter need by incrementing the counter by 2 instead of 1
* We will observe timer counter after calibration via serial display

stm32f407 adc dma
no vote
This example describes how to use the ADC3 and DMA to transfer continuously
converted data from ADC3 to memory.
The ADC3 is configured to convert continuously channel7.
Each time an end of conversion occurs the DMA transfers, in circular mode, the
converted data from ADC3 DR register to the ADC3ConvertedValue variable.
In this example, the system clock is 144MHz, APB2 = 72MHz and ADC clock = APB2/2.
Since ADC3 clock is 36 MHz and sampling time is set to 3 cycles, the conversion

stm32f407 EXTI
no vote
This example shows how to configure external interrupt lines.
In this example, the EXTI Line0 (connected to PA0 pin) is configured to generate
an interrupt on each rising edge. In the interrupt routine a led connected to
PD.12 pin is toggled.
