[font=宋体]I'm new here, hello to everyone! I'm doing OBDII diagnostic development recently, and I have a few questions to ask experts. Question 1: After connecting to OBDII J1850 PWM, it sends 0X61,6a,...
If the setting conditions are as follows:1. The port is set to trigger an interrupt at a low level.2. The interrupt Ena××e bit corresponding to the port = 13. The Ena××e bit of the total interrupt = 1...
I just got started with launchpad. The g2553 user manual clearly introduces adc12 and dac12, but why is there no interrupt definition for them in g2553.h, only adc10? Are they unusable? ? ? :Cry:...
I don't have any special requirements, a small board is fine. I don't have an emulator, so it's best if there's an onboard downloader. QQ21305767 [[i] This post was last edited by syaoraner on 2012-9-...
