I'm needing to do a bit banged SPI master using an 8051 variant from Silabs and I don't think I'm doing the best thing I could be to get a bit out the port. I don't think I'm doing the best job to figure out if a bit is high or low, then send it out the port. I'd appreciate it if

Trouble using AVRISP mkII to read flash of ATMega32U4

I found the problem by comparing AVR Studio build steps to the build steps used by Code::Blocks. Turns out that the ““-LC:\WinAVR-20100110\avr\lib” is excess and somehow interferes with gcc’s processor independent link sequence. I removed it and all is well. Problem solved … Chee
