名为startup_stm32f429_439xx.s的文件中使用汇编语言写好了基本程序,当STM32芯片上电启动的时候,首先会执行这里的汇编程序,从而建立C语言的运行环境,所以这个文件称为启动文件。该文件使用的汇编指令是Cortex-M4内核支持的指令,可从《Cortex-M4 Technical Reference Manual》中查到,也可参考《Cortex-M3权威指南(中...
This datasheet provides the description of the STM32F405xx and STM32F407xx lines of microcontrollers. The STM32F405xx and STM32F407xx datasheet should be read in conjunction with the STM32F4xx reference manual. 上传者:Tamias时间:2019-12-17 ...
case, it happens to be SPI2. Each peripheral has a different stream so that too is defined in the header file. There is a table in the reference manual (Table 20 in section 8.3.3) which shows how these are allocated. Here is a fragment from the header file showing the configuration ...
We have one device connected as “reference” temperature. Second sensor is placed near DC FAN, so when DC fan is turned ON, it is cooling the second DS18B20. The goal is, that both temperatures are the same. In my case, it was about 23°C on the reference sensor. ...
Under normal circumstances (when task is not pre-empted by RTOS) BTF flag should be never high immediately after DR readout (line 2803). Even if BTF was high before DR read, according to reference manual it will be cleared when DR is read. So, this check seems unnecessary. ...
This interconnection is explained in the section "TIM11 option register 1 (TIM11_OR)" of the RM0390 reference manual. From USB block to TIM USB block includes: • USB on-the-go full-speed (OTG_FS); • USB on-the-go high-speed (OTG_HS). 12/19 DocID027335 Rev 3 AN4640 ...
Deviation of the description in the reference manual or the datasheet from the intended device behavior is considered to be a documentation erratum. The term "errata" applies both to limitations and documentation errata. Reference STM32F405xx STM32F407xx STM32F41...
