The Timers can be cascaded to make more complex timing relationships, or longer periods. Internally only some timers can trigger others. This is a Master/Slave relationship and is handled by the SMS register. For example, you can see below that TIM8…
Apache 2.x keeps child processes alive by creating internal connections which appear in the log files as "internal dummy connection" on the IP address ::1 or 127.0.0.1. If you ever monitor Apache log files you'll see a lot of these in the log fi…
Timers TIM1 and TIM8 use 16-bit counters and are the most complex timers of all timers included in the microcontroller. Timers TIM2 and TIM5 are 32-bit versions of TIM1/TIM8, but have less hardware included and therefore less options. Timers TIM3 and…
STM32 System and Timer Clock Configurations I've started writing some software to drive a series of TLC5940 16 Channel LED Driver chips on an ST STM32F407 Microcontroller. I previously had code working on an Atmel microcontroller, but obviously with…
Timers get their clock source from External pins or Internal timer sources. External External = pins: TI1 or TI2 or ETR set pin to be used: in TIMx_CCMR1 reg - set pin to be used by writing CCxS bits select polarity of input in TIMx_CCER reg - write…
