  1. This snippet does not give the expected results (and I know I should be checking the return code of sscanf()...), the string contains text like "60.0" when asked for a frequency. float request = 50.0f; sscanf(string, "%f", &request); // having trouble since energia version 1.6.10E18 with floats... Under version energia_0101E0015, request becomes whatever float value is in the string (say 60.0), but under energia_1.6.10E18 request remains at the initialized value. Same with this snippet: sprintf(timecodeBuffer, "f# %04d ft %.03f %02d:%02d:%02d.%02d.%03d Squid_%c_[%02d:%02d:%02d.%02d] delta:%.03f \n", frameNumber, frameTime, computeHours, computeMinutes, computeSeconds, computeFrames, computeMilliSecs & 0x0000ffff, live, timecodeHours, timecodeMinutes, timecodeSeconds, timecodeFrames, timeDiff); Under version energia_0101E0015 it prints everything fine, but under energia_1.6.10E18 the floats are printed as a blank space. Computing with float values is not a problem. My include section looks like this: #include <Ethernet.h> #include <EthernetUdp.h> #include "inc/hw_ints.h" // our TM4C1294NCPDT is in the SnowFlake interrupt class #include "inc/hw_memmap.h" #include "driverlib/pin_map.h" #include "driverlib/sysctl.h" #include "driverlib/pwm.h" #include <string.h> #include <stdio.h> #include "Wire.h" // using the I2C bus for display My setup: Tiva-C connected EK-TM4C1294XL, 120 MHz tmc129 I tried upgrading to version 1.6.10E18. I really like the new board chooser and it downloaded the appropriate drivers and build tool chain. I think however the problem originated with the different tool chain. My OS is Kubuntu 18.04 LTS (with 32 bit libraries licb6:i386 for the lm4f tool chain to work under 64-bit ubuntu)
