IAR for STM8 redirect printf-EEWORLD

Collect

#include
int fputc(int ch, FILE *f)//STM8S105,printf function redirection
{
while (!(UART2->SR&0x80));
UART2->DR=ch;
return ch;
}

At the same time, you need to modify the Library item in IAR's Project->Options->General Options->Library Configuration from "Normal" to "Full".

Debugging STM8 with ST-LINK

Solved: What should I do when the error "The Flash Memory Read-out protection option must be disabled for debug. Disabling this option will first erase" appears when debugging STM8 with ST-LINK? (1) The prompt is very clear: you must disable the flash read protection option to debug, that is, you need to set it to r

stm8 bit band operation

STM8 and STM32 are different here. I am used to using LED = !LED in 51. In STM32, there is an atom to get the position and add macros, which is also acceptable. But stm8 doesn't support bit-band operations, so I searched on Baidu. There are roughly two methods: 1. STVD environment volatile _Bool PA_ODR_0 @PA_O

Notes on IAR debugging S3C6410 (Part 4)

The bare metal environment has been built. How can bare metal debugging be done without interrupts? S3C6410 has a hardware interrupt controller. Unlike 2440, you need to calculate the offset address of the interrupt function yourself. It is very convenient. For specific operation methods, please refer to the hardw

ADC0832 acquisition and Bluetooth communication system based on STM8

I recently found a single-chip microcomputer, STM8, while browsing Taobao. Compared with the 8-bit AVR I have been using before, STM8 feels more powerful. The chip features are as follows: Core: Harvard architecture with 3-stage pipeline, extended instruction set Program memory: 8K bytes Flash; RAM: 1K bytes Data me

Some points to note in STM8 design

1 、The PC0 and PC1 pins of STM8 only have OD open-drain output and no PP output, as shown in the following figure: If you want to use PC0 and PC1 to output high level, you need to pull them up during hardware design. These two ports cannot be pulled up by software and can only be pulled up by hardware. 2 , When u

Debugging STM32 in memory - IAR platform

　　The STM32 Cortex-M3 controller, like many other ARMs, provides two pins, BOOT0 and BOOT1, for boot selection. BOOT1=x BOOT0=0 Boot from user flash memory, which is the normal working mode. BOOT1=0 BOOT0=1 Boot from system memory. The program function started in this mode is set by the manufacturer. (For serial por

Detailed explanation of STM32 IAR project -> Keil MDK conversion

Introduction: I found that most of the STM32 sample programs are based on the IAR development environment when I was studying STM32, but I think it is more convenient to use the Keil MDK development environment, and I can use the powerful peripheral simulation function of RVMDK to accelerate the development of STM32. I
