| <p>Timer devices may be used for different purposes. One special purpose is |
| to generate modulated outputs for such things as motor control. If CONFIG_STM32_TIMn |
| is defined (as above) then the following may also be defined to indicate that |
| the timer is intended to be used for pulsed output modulation, ADC conversion, |
| or DAC conversion. Note that ADC/DAC require two definition: Not only do you have |
| to assign the timer (n) for used by the ADC or DAC, but then you also have to |
| configure which ADC or DAC (m) it is assigned to.</p> |
| <ul class="simple"> |
| <li><p>CONFIG_STM32_TIMn_PWM Reserve timer n for use by PWM, n=1,..,14</p></li> |
| <li><p>CONFIG_STM32_TIMn_ADC Reserve timer n for use by ADC, n=1,..,14</p></li> |
| <li><p>CONFIG_STM32_TIMn_ADCm Reserve timer n to trigger ADCm, n=1,..,14, m=1,..,3</p></li> |
| <li><p>CONFIG_STM32_TIMn_DAC Reserve timer n for use by DAC, n=1,..,14</p></li> |
| <li><p>CONFIG_STM32_TIMn_DACm Reserve timer n to trigger DACm, n=1,..,14, m=1,..,2</p></li> |
| </ul> |
| <p>For each timer that is enabled for PWM usage, we need the following additional |
| configuration settings:</p> |
| <blockquote> |
| <div><p>CONFIG_STM32_TIMx_CHANNEL - Specifies the timer output channel {1,..,4}</p> |
| </div></blockquote> |
| <p>NOTE: The STM32 timers are each capable of generating different signals on |
| each of the four channels with different duty cycles. That capability is |
| not supported by this driver: Only one output channel per timer.</p> |

| CONFIG_ARCH_LEDS=n : Disable board LED support |
| |
| Library Routines: |

| System Type -> STM32 Peripheral Support: |

| <p>NOTE: At this point in time, testing of the SLCD is very limited because |
| there is not much in apps/examples/slcd. Certainly there are more bugs |
| to be found. There are also many segment-encoded glyphs in stm32_lcd.c |
| But there is a basically functional driver with a working test setup |
| that can be extended if you want a fully functional SLCD driver.</p> |
