It is connected to the P0 port, let P0 = 0xf0; suppose s1 is pressed, when it is pressed, p0 = 0x70: then the value of P0 = 0x7f is assigned; key s1 is still pressed, after the assignment, is P0 = 0x7...
I drew a CC1101 transceiver board a while ago, but it was not successful. Finally, I found that the 27nH inductor was soldered into 27uH, which eventually led to failure.
Now after the replacement, it...
