Good Day I would like to know the reason I am receiving 0 values the hardware is good , have tested the sensor with a multimeter and am getting the desired output the wiring is 100% and have tested each and every cable it an analog signal and am using the Nucleo F446RE Pin PA_1 but getting ) value …

Ah thanks so much last question what command do I use to divide the answer by 1000 because I need it in km/h thanks [image]

Hi, I guess your switch-case usage is not correct, because you don’t have break statement for case blockes. Please refer this: switch...case in C Programming In this tutorial, you will learn to create a switch statement in C programming with the help of an example. The switch stateme…

Good Day I tried changing switch-case but still same result please find below [image] Code below :slight_smile: #include “mbed.h” AnalogIn Wind_vane(PA_1); //Analog in API for analog vane input connected to port pin PA1 Ticker Vane_Interrupt; //Ticker AP…

Hi, Please use ``` for code encloser. In you code, you are coping a value from AnalogIn instance to int variable and this may not work expectedly. Vane_ain_current = Wind_vane; //Read the vane analog input and store its value in the variable Please see API document. https://os.mbed.com/docs/mbe…

Hi I tried it still getting the same result :frowning: [image]

Hi, The read_u16 method of the AnalogIn class also doesn’t seem to be ISR safe. I run your code on the NUCLEO_F446RE target, I got exception below: Wind Direction is 0 Wind Direction is 0.00 Wind Direction is 0 Wind Direction is 0.00 Wind Direction is 0 Wind Direction is 0.00 Wind …

[image] MACRUM: int main () { EventQueue queue; queue.call_every(2000ms, Vane_Interrupt_handler); while(true) { printf("Wind Direction is %6d\n", Vane_ain_current); //Displays interger value read from vane analog input printf("Wind Direction is %4.2f\n",Vane_ang…

Please see: [image] Float Printf() doesnt work in desktop version Bugs Hello Laszlo, To reduce the code size Mbed introduced Minimal printf and snprintf . As of Mbed OS 6.0 it is enabled by default. Floating point parameters are only present when minimal-printf-enable-floa…

Hi Ok I sorted the output out but am still getting 0 values , [image] code currently running #include “mbed.h” AnalogIn Wind_vane(PA_1); //Analog in API for analog vane input connected to port pin PA1 Ticker Vane_Interrupt; //Ticker API intrrupt to creat…

Hi, Again, you need to use read_u16() meathod to get int type value fromAnalogIn instance. Vane_ain_current = Wind_vane.read_u16(); I’ve got this. [2023-01-18 21.25.05]

Hi, [image] Ajay_Parbhoo: last question what command do I use to divide the answer by 1000 You can simply use divide operator e.g. a = a / 1000;
