Mk_ 0 Posted September 5, 2012 Share Posted September 5, 2012 Hi all, I want to use the launchpad to build a DC motor position control system (for college). I want to use one channel from the adc (to read a potentiometer) and one pwm (to control the speed of the motor). As the "first step", i would like to only grab data from the adc with a fixed pwm, so to know the behavior of the motor. Since the backchannel UART is limited to 9600 baud rate, i came up with 2 ideas of getting this data: 1 - Use the HW uart (from G2553 for eg.) and a FTDI (or any other Serial->USB). 2 - Use one or more SPI EEPROM chips to save this data, and send them "offline" to the PC, using the 9600 baud. Does anyone know a better (or just simpler) way of getting this data out of the launchpad? I already have a working code, were when you send a character 'c' from the pc, the adc makes one acquisition and send it back through the uart, but i cannot achieve much high rates.
