Passing float value to UART buffer ?

[antonius]

Dear Members,

How can I pass float value from RPM to UART buffer

float ==> (uint8_t*)&aTxBuffer8 ?

(uint8_t*)&aTxBuffer8 = snprintf(str_rpm,sizeof(str_rpm),"%f",rpm);

?

Thanks

Is it working, or do you ask these things rhetorically?

Pointer and length, check those.​
