When I soldered before, I just glued a few pins of the chip, and the jtag couldn't connect. Later, I tried a few more times, and the chip blew up almost every time. I was so scared that I didn't dare ...
I used two external interrupts, but one of them was not triggered. Once the program was executed, it entered the interrupt. I don't understand why.Also, sometimes there is a fluctuation on the pin, wh...
After searching online for a few days, I have summarized a few questions. Please give me some advice: 1. Does MapX Mobile support EVB3.0+PPC2002? (According to some people online who have done this, i...
I got the board almost after the holiday, but I kept delaying it, so I'll post an unboxing post now.
First, let me introduce this development board.
