I am interfacing TSC2046 with Atmega16 and sending the command word 0xDF( to measure X) and 0x9F( to measure Y) through SPI bus. I am using SCK as 2MHz. But I can not receive the SPI data properly according to Touch screen and sometime the busy signal remain high and receive 00 or invalid data...
Thank you alexan_e. AVR Fuse bit doctor uses another mcu that contained a firmware I am searching for a circuit that can repair SPIEN bit directly through parallel or serial port through pc program without using firmware of another MCU... Is there any such circuit or program??
AVR are programmed through using MISO, MOSI, SCK & RST signals. So in that case can I can program the avr in parallel mode and can I change back SPIEN bit?
Please refer me software and hardware schematic of programmer.
Thanks in advance.
