  • Forum Post: F28035 SCI/LIN Interrupts Stop

    George Walker
    I have ported an application from F2810 to F28035. The F2810 version has been running for several years. On the F28035 it runs for a couple of hours, after which I no longer get interrupts from one of the two serial ports (SCI or LIN in SCI mode). If I halt in this mode, I see that the peripheral has...

    Jon Kelm
    We have a custom board that we just redesigned to use a 28235 DSP instead of the 2809 that we were using previously. We have several analog signals going to the ADC inputs. I am seeing lower ADC result values with the 28235 than I would expect, while I see the correct values on the 2809-based board....

    Hi, Dear Friend before you try measure anything, you need to condition the signal to Microcontroller acquire your signal. Your full scale of ADC is 3.3V to unipolar signal, then you signal need to be between 0 and 3.3V . What's is a range of your signal, current and voltage? Is AC or DC? This...
