    Sunil Oak Sunil Oak
    Hi, The offset error calculated using the method described in the TRM can be negative (conversion results lower than expected) or positive (results higher than expected). The contents of the ADCALR register get added to each conversion result output from the ADC core before they are stored in the...

    Sunil Oak Sunil Oak
    Hello, The resistances R1 and R2 are typically 7K-ohm and 5K-ohm respectively. These values are selected such that two combinations of the BRIDGE_EN and HILO bits yield 7/12th and 5/12th of VREFHI as the reference voltage converted (with VREFLO = 0V). The {BRIDGE_EN = 0, HILO = 0} combination gives...

    Daniel Dueringer Daniel Dueringer
    I'm trying to calibrate the ADC of the Hercules evaluation board for the TMS570LS3137. I have configured to ADC to use 12bit values, but I get 10bit values from the ADCALR register instead of 12bit values: - low: 0 - middle-low: 426 - middle-high: 597 - high: 1023 In the figure 18-10 from the technical...

    pajani CHANEMOUGA pajani CHANEMOUGA
    We are developing a safety control board; we are using microcontroller TMS570. To validate our algorithms of control, we would like to design a prototype from the Hercule Developement Kit TMDX570LS31HDK and some I/O interfaces. and we would like help from specialists on the following points: -...

    Jean Marc, Thanks for your answers. I need some design examples for interfacing the MCU to the sensors ( the voltage and the bandwidth are respectively of 5V and 500Hz) Best regards Pajani

    David Rodriguez Rodriguez David Rodriguez Rodriguez
    I am using the microcontroller TMS570LS3137, I don´t know if it is possible to configure a number of samples of the ADC before enable interrupt, in order to perform a more reliable conversion. My setup is: 12 bit resolution Single conversion If that is possible, what are the registers...
