Hi, people. There is a small bug fix to the software UART I sent to some of you. In the UART.asm file change  // Enable and set up SPORT1 as FI and FO pin  ax0 = b#0000100000000000;  ay0 = Sys_Crtl_Reg;  ar = ax0 or ay0;     // Enable SPORT

I hve a project on my hand. Originally, the project used AT91FR40162(ARM7TDMI) to connect to ADSP-2185's SPORT(DR1, DT1, SCLK1) via 3 pins...

I hve a project on my hand. Originally, the project used AT91FR40162(ARM7TDMI) to connect to ADSP-2185's SPORT(DR1, DT1, SCLK1) via 3 pins (RXD1, TXD1, SCK1) operation on synchronous mode of USART. Data Rate = 480K bps. But now, we want to change the MCU to PIC18F8722(PIC). PIC uses 2 pins(CK1, DT1) when it operates on synchronous mode. Problem: 1. How does the PIC(2 pins) connect to the...

Hi, I need to make .wav file driver on BF537 board. I have AC97 compatible AD1981 codec on our board connected to BF537 via SPORT interface. Can some body explain me how to start with it? I want to know how can read/write the code registers and how to send the PCM data to the codec. I did .wav file driver for BF537 Ezkit. Here I reset the codec and the reset state of the codec wa...
