WebOct 28, 2015 · Reading the value of the pin will give you the logical value of the voltage applied to the pin. The voltage levels which correspond to a 0 or 1 are available in the devices datasheet. For example for the STM32F401 a voltage of up to (maximum) 0.35*VDD-0.04 V will be considered low or 0. A voltage of at least 0.4*VDD is considered … WebJul 29, 2015 · 2 这个函数传入的参数是GPIO_TypeDef和GPIO_InitStruct,GPIO_TypeDef是一个数组,包含了所有GPIO相关的寄存器。 ... 把GPIO的某一位写0或者写1. void GPIO_WriteBit(GPIO_TypeDef* GPIOx, uint16_t GPIO_Pin, BitAction BitVal) ...

WebApr 9, 2024 · 本程序使用stm32f103c8t6作为主控单片机,4针0.96寸oled屏幕作为显示。采用硬件iic方式,硬件iic的特点就是比模拟iic数据传输速度快,并且数据传输速度是可控的。程序可完成基本的英文字符显示、数字显示以及汉字显示,也可实现画点、画线以及图片的显示。 WebFeb 6, 2024 · 0 Currently, I'm facing a weird problem with the STM32. I just generated code with the STM32Cube IDE for the chosen MCU (STM32L031G6). I nearly didn't change anything, except configuring one GPIO as output and trying to let a connected LED blink. Now the problem: If I run the code, nothing happens, no blink at all. cryptoflowers

WebOct 2, 2024 · The code lines that are confusing me are these two: GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Pull = GPIO_PULLUP; So they are using push-pull mode in combination with a pullup. Why would you do that? I can't think of a use case. Either the output is high anyway, then the pullup won't be necessary. WebMar 2, 2024 · Timer1 doesnt generate an Output while Timer3 does (STM32L552) I am trying to use the output compare mode of TIMER1 to produce an accurate time course on the PE9 pin. For some reason I don't get an output signal on this pin. Instead, when I use TIMER3 with the same settings as TIMER1, I get an output signal on pin PC7. WebMar 9, 2024 · \$\begingroup\$ Regarding ST and their libs, they are very confused over existing computer science terminology in general and I wouldn't trust anything said in their docs. A real HAL is for example an abstraction around drivers, for the purpose of separating application logic from hardware details.A mere wrapper around code accessing hardware … crypt staff
