I have installed the USBasp drivers – the installation is quite straightforward thanks to the guide. I have the USBasp programer and I’m trying to burn bootloader on Atmega328 so that it can be used as a replacement chip in Arduino board (replacement chips with the bootloader installed are quite expensive). I’d be very thankful for any help! Please let me know if you need more information. Mcp23s17_Write(self, (char)port, direction) Void Mcp23s17_SetPortDirection(Mcp23s17 * self, Mcp23s17Portdirection port, char direction) Mcp23s17_Write(self, IOCON, IOCON_BYTE_MODE | IOCON_HAEN) Void Mcp23s17_Initialize(Mcp23s17 *self, int * sfr_address, int sfr_pin) This is the main function: #define PB_SPI_SS_MCP23S17 PB2 Please assume all necessary headers as included (I’m not a C-beginner is what I want to say). The problem is that I’m sure that my code is also correct. I want to apologize in advance for that much code but I really double checked everything already and I hope that someone might see what I don’t. I’ve double checked my circuit and I’m sure that I did that right. Since three days I’m having the problem that I can not talk to my MCP23S17 SPI I/O Expander from my ATmega8. Note: watchdog (WDTON) fuse bit is disabled. The code works well for the first time, but after that, LED keeps blinking. This is a simple code to check the watchdog timer but it keeps resetting the controller. Now I am testing the new controller in every aspect. I was using ATmega32A before and now I am migrating to ATmega324PA just to enhance power management. Q2: Each time that I call w1_read function, DS2401 send me next 1 byte? or the same first 1 byte? or total of the ROM?

I want to read my DS2401 chip with AVR ATmega32, and I use 1wire.h library in codevision.Īs mentioned in Codevision AVR User Manual I must use w1_read() function to read a byte of DS2401. So for communicate with this chip there is a protocol that called 1-Wire. One of them is ground and one of them is Data/ Power pin. DS2401 is a 64-bit ROM memory that used as a hardware-serial-number.
