А если PORTB.2 мне нужен для другого, что тогда делать?

doesnt matter : as long as you use it in OUTPUT mode.
But hey it worked with the bootloader right? so that can not be a problem!

My explanations are not always directed to exact the one person I address, instead I keep the faint hope, that others, for example the TO may draw some knowledge out of it.
Alas it does not work always:

@sasha_1973: If PB2 is output, you use it the same, as you do now.
If PB2 is input and hardware-SPI is required, there's always a soldering iron and some wire somewhere.
Alternatively: get soft-SPI to work. |

Я пробовал программный SPI, эффект тот же самый, не работает?
I tried program SPI, the same effect, doesn't work?
Config Spi = Soft , Din = Pinb.4 , Dout = Portb.3 , Clock = Portb.5 , Ss = Portb.0
Spiinit

This is called discussion forum.
A discussion is defined by questions and replies, this applies to both sides.
I get tired of playing the fool by trying to answer every of your questions, without getting proper feedback.
These are not just problems in translation anymore, this is something about your discussion style and your responsiveness, which is both unacceptable.
Don't forget, I get my things to work, I do not need you to fix something, it may look different the other way.
So, before I answer any further of your questions, or even think about how to help you further, first answer my question:
Does it work with PB2 set to output and hardware SPI?

Полностью заработал ( Bootloader; USBISP; USBISP MKII) такой вариант:
Completely I earned (Bootloader; USBISP; USBISP MKII) such option:
| Code: | Const Const_realization_spi = 0 ' If "0" - implementation of hardware (hardware terminals), if "1" - implementation of software (any conclusions)
#if Const_realization_spi = 0
Config Spi = Hard , Interrupt = Off , Data Order = Msb , Master = Yes , Polarity = High , Phase = 0 , Clockrate = 4 , Noss = 0
#endif
#if Const_realization_spi = 1
Config Spi = Soft , Din = Pinb.4 , Dout = Portb.3 , Clock = Portb.5 , Ss = None
#endif
Cs_max7219 Alias Portb.0 : Config Cs_max7219 = Output
Spsr.0 = 1 ' F_spi = F_osc / 2; Double Speed (CK/2) Master SPI Mode
Spiinit

MWS и albertsm, ОГРОМНОЕ СПАСИБО за помощь!
Проблема была в Noss = 1, надо Noss = 0 . Хотя в справке написано - "1 or 0. Use 1 when you do not want the SS signal to be generated in master mode".
MWS и albertsm, MANY THANKS for the help!
The problem was in Noss = 1, Noss = 0 is necessary. Though in the reference it is written - "1 or 0. Use 1 when you do not want the SS signal to be generated in master mode". |
