Coocox kullandım. Ancak keil ile derlenmesini engelleyecek bir kod yok. Coocox kütüphanelerini kullanmadım. Tamamı ST kütüphanesi.
Hatalar neler?

Hata mesajı.

A registeri için, a->x=0x123143 şeklinde olmadıkça anlamıyorum ne olduğunu.

Gerekli kütüphaneleri projeye dahil etmemişsin ve/veya header dosyalarını incude etmemişsin. Hata mesajlarını bu sebepten alıyorsun.

blacklogic · 06 Ekim 2013, 20:09:29

Eklediğim kütüphaneler bunlar. Eksik olan nedir acaba ?

Klein · 06 Ekim 2013, 21:14:47

stm32f10x_gpio
stm32f10x_rcc
stm32f10x_tim

blacklogic · 06 Ekim 2013, 21:31:59

Alıntı yapılan: Klein - 06 Ekim 2013, 21:14:47
stm32f10x_gpio
stm32f10x_rcc
stm32f10x_tim

stm32f10x_tim bu kütüphaneyi bulamadım, diğerleri var. Acaba sizdeki kütüphaneyi buraya koyabilir misiniz?

Hocam kullandığınız işlemci nedir ?

Klein · 07 Ekim 2013, 19:31:30

STM32F103C8

mesaj birleştirme:: 07 Ekim 2013, 19:35:17

void init_pwm(void){
TIM_TimeBaseInitTypeDef TIM_TBInitStruct;
TIM_OCInitTypeDef TIM_OCInitStruct;

     TIM_TBInitStruct.TIM_Period = 50000; // taşma değeri.
     TIM_TBInitStruct.TIM_Prescaler =47;

Kodun burası hatalı. Periyot değeri 4999 olacak. Yanlışlıkla değiştirmişim. Şimdi düzeltemiyorum.

muhittin_kaplan · 07 Ekim 2013, 20:32:56

ben 100rb ile çalıştırdım 24mhz de 10hz oldu.
sonrasında değerleri değiştirdim.

esas problemim şu oldu, HC-SR04 5v çalışıyor. neden bilmiyorum CapIN girişine bağladığımda çöküyör sinyal (PA6)

Klein · 07 Ekim 2013, 20:36:27

PA6 aynı zamanda analog input. !!!! ANALOG GİRİŞLER 5V TOLERANSLI DEĞİL !!!!!

muhittin_kaplan · 07 Ekim 2013, 21:24:30

muhittin_kaplan · 12 Ekim 2013, 18:00:32

capture pini ni değiştirsem (ain olmayan biriyle mesela) ?
