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

Hi everyone, I use the following function to compute the angle from accelerometer: float a =atan2f(-0.143798828, -0.680053711); But it can not return a proper result (a huge number ~10^22). How I can compute the angle directly on the chip. (I used CCS IDE). Thanks!

hi, I am using a MSP430FR4133 launchpad, i am trying to get a float value and send it via sim800. for that i hve to convert the float value to char* or char array. I have tried many conversions but i am not able to get the conversion properly. Even if i get it properly while printing it on the serial. The data is not transmitted in the right format through sim800. for example if i use dtostrf( buff , "%f" , flaotVal); function in serial monitor only "%f" is getting printed. and if i try other type of convertions , while transmitting through sim800 the right side part of the floa

char final[6]; sprintf(final, "%.3f",current); Serial.println(final); When I put this code to calculate it prints only the "%.3f" I know floating point is not good to use for MSP430, but I do need the decimal places for my calculated results and need to convert to string pass on java socket. Or Can someone introduce me the fixed point calculation? many thanks!

Hi Everyone, I have been looking for about an hour online and haven't been able to find the answers to these questions. - Can I use floating point with the msp4302553 ? the watch expression on CCS don't seems to like floating point for sure. - Can I use math.h to do trigonometry calculus on the msp430g2553 ? Let me tell you guys what I am trying to do so that it is more clear: I am scanning a signal with an ADC. I would like to do an atan() on the signal and output the signal with an DAC. Right now I can scan the signal and send it to the DAC. This works well. But I can't get the t
