STM32 SPI obtains the angle data of magnetic angle sensor AS5048A AS5048A is a 14 bit precision magnetic angle detection sensor with SPI interface. In fact, the stability accuracy is only 12 bits, that is, when the detection environment is static, the last two bits of data output are changing and not constant. AS5048A can be used for rotation ...

STM32 input capture function uses TIM2 and TIM3 to capture 8-channel waveforms at the same time. One of the requirements of work is to collect two groups of signals to control the stepping motor. It is to collect the square wave of 8 channels, measure the frequency and count the number of pulses. What looks simple has been bumping and bumping ...

Generate Keil project with CubeMX: Skip other basic parts. Here are some points that need attention. Configure the system debugging pin and select the ...

1, System clock 1. Clock tree 1. The system main frequency of mx6u is 528MHz, but by default, the internal boot rom will set the main frequency of I.MX6U to 396MHz 1. The system clock of mx6u-alpha development board comes from two parts: 32.768KHz crystal oscillator and 24MHz crystal oscillator. The 32.768KHz crystal oscillator is the RTC ...

preface The chip STM32H750 is used in a recent project. Its on-chip flash is only 128KB in size (although it is said on the Internet that it actually has 2MB as H743, this method is not used for insurance). Because the project uses RTOS, LWIP, TLS, etc., and the generation program is relatively large, W25Q32 (4MB in size) is added as off chip ...

RTOS task switch ...

FREERTOS learning notes III - message queue 1. Experimental contents Experiment 2: create two dynamic tasks. Task 1 controls the flashing of LED, and task 2 is used to detect keys. When the key KEY0 is pressed, task 1 is suspended; When key 1 is pressed, task 1 is cancelled and suspended. In Experiment 3, a message queue and two task process ...
