I used the Flash_API library function provided by TI to program data into the on-chip Flash of F28335 on the SEED_DEC28335 development board of Hezhongda. I encountered many problems. First of all, I ...
小弟去下載USB的3.3.0的資料庫,裡面有EVAL的Virtual COM Port程式,想要一直到我的板子上,對照了電路圖,小弟的板子不是市面上的開發板,用的IC是STM32F102R8,USB的PULL UP控制是在PB9,照原本的是設定在platform_config.h裡設定是PD9,把它修改成PB9後變成一直在卡在USB中斷那邊,後來追到stm3210b_eval.h裡的PB9有重複定...
Let me talk about the problem first... It's the problem in the matrix inversion scanning function... The source function is as follows... unsigned char KeyScan(void) //Keyboard scanning function, usin...
The project requires that the routing and terminal nodes be selected by the program. Can zstack support this function?
By modifying the code, in routing mode, debugging found that the program cannot e...
The efficiency curve of the BUCK buck board (36V, 48V, 60V to 12V 15A) using ON Semiconductor's (actually it has nothing to do with ON Semiconductor, other companies are also fine) UC3843 is measured....
In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer
