I studied STM for a while a long time ago and asked this question.Today, I am quite free and I am still confused when I think of this question.I was going to draw the JTAG debugging port according to ...
I am participating in a competition and am required to use a Renesas chip. I chose upd78F0746. After the hardware design was completed, I found that the compiled program exceeded the space limit (16K)...
Regarding the PHY construction of LWIP, the PHY chip used is LAN8720A, RMII mode. Regarding the hardware connection part, the Atomic board F407 is used, and the hardware connection is as follows: ...[Details]
Site conditions: 1. AD acquisition, DMA transmission; AD is set to single-channel continuous mode, DMA is set to single-shot mode. The upper threshold of the AD analog watchdog setting is less than t...[Details]
I used the bit definition in my 51 program: bit flag. After defining it this way, I ran the program and downloaded it to the circuit board. I found that the flag was not the value I set, which led to...[Details]
The Vatican Secret Archives is one of the world's greatest historical collections, but many of its documents have never been transcribed. Recently, a project called Codice Ratio used a

OSC_IN and OSC_OUT are external crystal pins by default. If you do not use an external crystal oscillator on the STM32, how to connect OSC_IN and OSC_OUT If you use the internal RC oscillator instead...[Details]
Interrupts and timers implement a 24-hour clock. The program is as follows: #include reg52.h #define PORTLEN P0 sbit bit_select = P2^0; sbit seg_select = P2^1; unsigned char src = {0x3f,0x06,0...[Details]
;The hardware connection circuit of the 51 single-chip microcomputer is as follows: ;P1.3 and P1.4 are each connected to a button; ;P0.0 and P0.3 are each connected to a light-emitting diode; ;P2.0~P...[Details]
Take serial port interrupt as an example: like: void serial() interrupt 4 { } and void serial_uart() interrupt 4 { } The functions of both functions are to define the serial port interrupt function. ...[Details]
