Remove the groove in the box and compile once, then check and compile again
After that, it will be fine. However, this trick does not work for all versions of IAR. Version 8.30 is the most stable. Every time this trick works, you have to wait until the green accuracy bar below reaches the end when you check the box to compile again.
Second, if you use the first method and find that Generate browse information is already checked, then click VIEW -> source browser to open the code browsing window, as shown in the figure:
So I recommend friends to use version 8.30 of IAR, this version works every time.

STM8 and Assembly Language (10) - UART Application 2
The following experimental program is relatively simple. It is based on the previous one and adds a subroutine to receive a character from UART in a query mode. In the main loop, it waits for a character to be received and then sends the received character out. If it is connected to the WINDOWS hyperterminal, the corr

OSAL porting to STM8
Recently, I need to use STM8S105 as a driver controller, which involves using 485 to communicate with the host computer, and CC2541 is used in the Bluetooth module of the host computer. This is a new product, there is no code to refer to, and there are many protocol solutions and logical structures involved. I planned

STM8 clock switching
HSE, HSI, and LSI can all be used as the system's main clock source. After the STM8 microcontroller is reset, the default frequency division of HSI is 8 as the system's main clock. The reason is that the HSI has a short stabilization time, and its frequency division of 8 can ensure that the system starts safely under

About STM8 program download problem: Summary of solutions to SWIM Error [30006]
I am also a victim of Windows users. It is a painful experience for me to spend one day programming and two days configuring. I also encountered this problem. Although I found that the chip was wrong, I studied it for several days. In order to avoid searching online again next time, I will summarize my current solutio

B-1.19 Protocol Analysis--STM8 uses its own bootloader
1. First, confirm whether the STM8 you are using has its own bootloader. Refer to the table below: 2. The STM8 blank device can directly use its own bootloader. 3. After the STM8 is burned using SWIM, if you want to continue to use its own bootloader, you must set the optional byte to 0x55AA. As shown in the figure b
