The GPRS module I am using is BENQ's M22A, and the ARM is lpc2136. Wow, now I want to use the module without TCP/IP protocol to access the Internet, so of course I have to set up the protocol myself. ...
I wrote an i2c device driver myself, but after testing it with an application, I can normally operate the open, read and write in the kernel's built-in i2c-dev.c (the device node is i2c-0), but I cann...
TCPMP plays videos and it gets stuck. I tested the speed and it was 102%. I want to know some ways to increase the speed. How can I increase the speed? In the TCPMP settings, it shows the main frequen...
I use the SPI simulated by the I/O port to operate the M25P80. When I write in, the wrong data is read out, and it is all the same value. It seems that nothing is read out at all. Now I don't know whe...
