The difference between the STM32 data sheet and the technical reference manual-EEWORLD

Collect

There are two main types of technical information about the performance parameters and usage of STM32, one is called a data sheet, and the other is called a technical reference manual or simply a reference manual.

The data sheet is a basic description of the product's technical characteristics, including the product's basic configuration (such as the capacity of built-in Flash and RAM, the number of peripherals, etc.), the number and allocation of pins, electrical characteristics, packaging information, and ordering code.

The Technical Reference Manual is specific information on how to use the product, including details such as the internal structure of each functional module, descriptions of all possible functions, use of various operating modes, and register configuration.

Usually, in the early stage of chip selection, you first need to look at the data sheet to evaluate whether the product can meet the functional requirements of the design; after basically selecting the required product, you need to check the technical reference manual to determine whether the working mode of each functional module meets the requirements; when you enter the programming design stage after determining the selection, you need to read the technical reference manual in detail to learn the specific implementation methods of each function and the configuration and use of registers. When designing hardware, you also need to refer to the data sheet to obtain information such as voltage, current, pin allocation, and drive capability.

STM32 FSMC configuration SRAM

The FSMC of STM32 is really convenient. It can be expanded to include SRAM/NOR/NAND/PC Card/TFT, etc. It is very easy to operate. For more information about FSMC, please refer to the STM32 Reference Manual, which is very detailed. Engineering structure: user_sram.c //function of code:FSMC SRAM Driver SRAM

STM32 learning notes: ADC understanding

Introduction to ADC The 12-bit ADC is a successive approximation analog-to-digital converter. It has up to 19 multiplexed channels and can measure signals from 16 external sources, two internal sources, and the VBAT channel. The A/D conversion of these channels can be performed in single, continuous, scan, or disconti

SYS_TICK configuration for STM32

1. SYS_TICK is not a peripheral, but a part of the kernel. There is no description about it in RM0008. 2. This is a 24-bit counter that can generate internal interrupts. 3. Its interrupt can generate an interrupt without configuring the NVIC properties. 4. If you need to configure 8-frequency division, you need to con
