I use an AVR microcontroller to implement SPI communication. I use two chips to communicate, one is a host and the other is a slave. However, the SPI protocol does not have a flow control setting. Whe...
First, use C809 to make an open-loop PWM controller: Refer tofor the configuration process: void TAU0_ini(void) { TMMK00=1; /*enable TAU channel0 interrupt*/ TMMK01=1; /*enable TAU channel1 interrupt*...
Regarding the relationship between capacitance and frequency, coupling capacitors, filter capacitors, bypass capacitors, etc. are often used in amplifier circuits. I want to know the relationship betw...
I have a question for you. When there is no program in the FLASH on my S3C44B0 board, or I have directly erased it, can I use AXD to simulate and debug it in SDRAM through the JTAG port? Some people s...
1. Introduction
The Bluetooth connection has been introduced before, so we need to do something interesting. The board does not have its own audio interface, but it has Bluetooth, so I thought of usin...
