Motorola MC68HC908AB32 Proto Board Help for ISP
Posted: 22 Jun 2021 17:26
Hello again!
Presently I'm trying to get a protoboard going for the Motorola MC68HC908AB32. I've created a board and installed the device. Then I replicated the circuit provided in the Device Information. Dataman-48Pro2
Many pins are left floating, but all of the VSS and VDD are in parallel, Crystal Oscillator is added, capacitor on the power, and Short leads to the programmer.
I'm using the Dataman to power the IC.
I'm getting the "Device Does Not Respond" error.
Can you please put me in the right direction for making the needed adjustments to my proto board?
Also, is there a way to connect to the Socket instead of the ISP connector so that I do not have to have a protoboard with its own oscillator etc?
Respectfully,
Tyler
