Posted on June 30, 2018 at 13:52Hi everybody!I have a problem with the TIM2_CH1 output pin on STM8L051F3 (20-pin TSSOP).In the datasheet (Rev. 3), there are 2 options for the TIM2_CH1 signal: PB0 (pin 10) and PC5 (pin 1); but I cannot find anything ...

I remember years ago, when Microchip acquired ATMEL. AVR8 micros were getting harder to find, prices going high and they stopped developing the new (back then) ATxmega family. I was so upset, I immediately started searching for an alternative to the ...

At line 2, the sim instruction disables interrupts before testing the event flags. If none are set, it goes to sleep (wfi) - but this is the good part, when executing teh wfi instruction the interrupts are enabled again and the pending interrupt is b...

Hi!Below is one of the ways I do it (with priority event handling), but it is in assembler:forever: sim ld A, EVENT_REG jrne f_tst f_slp: wfi sim ld A, EVENT_REG jreq f_slp f_tst: rim bcp A, #(1<<EVENT_0) jrne f_event_0 bcp ...

Hi!When you wakeup from active halt mode to read the register about VREFINT status, or before you execute the halt instruction, the VREINT will automatically be enabled. This is why you always read it as 1, on.So, the voltage ref. will only be disabl...
