ChibiOS Free Embedded RTOS

sorry about that i did not realize what you meant until you hit me with it :oops: everything is working good now except when i try to use the buffer to give a drawline value eg. 245(i have striped the buffer back to that) it will not work i get the assignment makes pointer from integer without a cas...

i have tried getting the voltage to display this way:
float voltage = (adcsample_t) samples2[0];
sprintf(buffer, "voltage: %fV", voltage);
but it reads " voltage:4063.000000V" off a 3v pin.
am i doing it correctly or should i be doing some sort of calculation first?

ok that works but how do i tie that to samples

disregard my fault..

i cannot see the attached stubs either

what syscalls should i add?--
ok i found syscalls.c and have added it to my makefile

i know i probably sound stupid but how do i convert the buffers into strings i have tried and all i get is random characters on lcd

yes that is the example i am using but where do i get the result from i cannot see where the result is in the example?

well yes thats exactly what i want to do just having a hard time figuring out how i get the conversion value.

was just trying to start by using the testhal adc example to read a voltage (3.3v) and display it on my lcd and then take it from there..
