I have 5 tiva launchpads connected to a 7 port usb hub. I can select the com port in the Energia IDE but when programming, the IDE "says Found multiple ICDI devices with serial : " and gives up. Is there any way to program the launchpads through the hub?

I am using a 80 mhz tiva tm4c123 in energia. I want to use the QEI velocity register by loading the QEI LOAD register. There must be a system clock clocking this register. What is the frequency to the qei timer? (what register determines the frequency this module)?

Analog-to-Digital Converter Run Mode Clock Gating Control (RCGCADC), offset 0x638 must be enabled before reading or writing adc registers. So if you don't do this, it hangs. It may be that other sections need to be enabled before read or writing.

www.ros.org has a rosserial interface for ardunio. There is a ardunio.h file in the ros_lib. Has anyone written a similar file for energia (tiva or ms430) and gotten it to work?

I would like to write and read tiva registers in energia, but it crashes on the register name below. Does energia support this? the "inc/tm4c123gh6pm.h" file contains #define ADC0_SSFIFO3_R (*((volatile uint32_t *)0x400380A8)) #include "inc/tm4c123gh6pm.h" // ti register names #include "inc/hw_adc.h" #include "Wire.h" void setup() { Serial.begin(9600); unsigned long reg = ADC0_SSFIFO3_R; // compiles but crashes when running it }

I am moving from Arduino to the Energia 10 stellarpad/tiva and what worked there doesn't work here. The Serial.println("inByte"); won't print in the serial window. Later on, in the loop portion, it will print. void setup() { // start serial port at 9600 bps: Serial.begin(9600); Serial.println("inByte"); // doesn't print }
