I have finished the design, and its running like a charm. Issue was:
- No diodes over the resistors (did not think it mattered during test for proof of concept), but they ensures a fasst kill time for the FETs, and the resistor ensures a somewhat delayed rise time.
- Increased the HDEL and LDEL...
So this was the first draft - In the mean time i have split the circuit into two boards to seperate the controller from the high power.
But any inputs are welcome.
- - - Updated - - -
but... i would like to add, i have now added a 200K resistor pots on the HDEL and LDEL, I can now controll...
Problem solved, my fault, forgotten that I had to use the "slow CLK" option on the USBasp to get in contact with the non-xtal default chip. and when setting the jumper, disconnect and reconnect the USB to boot the USBasp up in slow mode.. dont know if it was nessesary, but it worked for me.. It...
Im using winav+avrdude in eclipse, and im unable to get a new chip to recognize with avrdude/avrasp dongle.
I can program a chip i have, without any problems, but when i put in a new chip atmega8, i get "avrdude: initialization failed, rc=-1", so im unable to program any fusebits in it at this...
Hi,
This is my first post, and value this board as a helpfull area for information and help.
So Im building a PWM controller to controll a pair of electric chair motors, this natually needs to be PWM controlled. I have done alot of research on the net on different designs, and have come up...
