Use of STM8 interrupt vector in IAR-EEWORLD

Collect

According to IAR rules, the interrupt vector should be increased by 2. For example, if the interrupt vector of the PA port is 3, then #pragma vector=0x05 should be written in the IAR program. However, PD7 is different from other PD ports. PD7 has a small tail TLI. TLI has the highest level interrupt of the chip and has an independent dedicated interrupt vector number 0. Therefore, according to IAR rules, the vector number should be increased by 2, and the program should be changed to #pragma vector=0x02, instead of the other interrupt number 0x08 of the PD port.

IAR FOR STM8 The same project chip selection 003F3 can compile 003K3 and prompt insufficient space

For the same project file, if you select 103F3, it can be compiled successfully, but if you select 103K3, it will prompt that there is insufficient space. I was puzzled and consulted a lot of information but to no avail. Finally I found the configuration file in the IAR project. Open the configuration file of 0

Configuration and reasons of linker file of atmega128 bootloader program under IAR-AVR

Step 1: The on-chip flash partitions of atmega128 are described on page 275 of the atmega128 datasheet. Correspondingly, on page 284, there are specific settings for the size of the application area and the boot area. Note: Byte address = word address * 2 Here, the first address of the BOOT area, $F000 = 0x1E000

Observation of the output frequency of each clock CLK_CCO port of STM8

Note: You need to enable port D0 function as CLK_CCO in the option bytes Modify the AFR2 option bits in ST-LINK/Option Bytes: It should be noted here that the clock source used is not after the main clock switch, so no clock switching is required. Here we need to use the CLK_CCO port to output the waveform. Acc

IAR STM32 absolute address positioning of functions and variables

Yesterday, I suddenly had an idea: can I use the absolute positioning of functions and variables to achieve modular updates of programs? In other words, if I want to change a function, I only need to update a part of the flash, maybe only a few hundred bytes, without having to re-download the entire hundreds of KB
