이정도면 위중증도 500넘었고
위드코로나 실패를 인정하고
이전으로 돌아가야 하지 않을까 생각된더.
저번주에는 포기한다 할줄 알았는데 그러지도 않고
너무 늦은것 아닐까..

배선 문제로 pan만 연결했는데
전원부가 미친듯이 열받아서 보드를 손으로 잡고 있기 부담스러울 정도라
나중에 esp32와 서보 전원을 분리해서 만들어야 안정적으로 작동이 가능할것 같다.
IO15가 pan
IO14가 tilt 로 구성해둔 듯.

으허어어엉 안테나가 문제냐
rtl sdr이 문제냐 ㅠㅜ
[링크 : https://ko.m.wikipedia.org/wiki/다이폴_안테나]
주파수는 NOAA15나 NOAA19니까 대충 때 맞춰서 보면 되고
방향이랑 위성은 stellarium으로 확인
그런데 자이로가 문제가 있는지 방향이 안 맞을때도 있으니 방위는 미리 확인해두는게 좋다.
최근접이 1100km 근처이긴 한 것 같은데
신호가 저~~~~언혀 뜨질 않는다. 하긴 FM 라디오도 잡음이 심한데 위성 신호는 더 못잡는게 당연한걸려나?

아키텍쳐가 달라서 완벽한 비교도 아니니 참고 수준이지만
cortex m3 보단 낫고
cortex m4 와는 비근하지만 약간 쳐지는 수준안가?

웹 어셈블리에서
인자로 입력 받아 결과를 웹에서 받는 예제를 찾아봄.
wasm으로 변환될 코드는 int 형을 받아서 int 형으로 출력할 것이고
#include <math.h>
extern "C" {
int int_sqrt(int x) {
return sqrt(x);
}
}
빌드는 아래와 같이 emcc를 통해 ccall과 cwrap 방식으로 _int_sqrt 함수를 내보내라 인것 같은데
int_sqrt가 아니라 _int_sqrt는 calling convention때문인가?
| $ emcc tests/hello_function.cpp -o function.html -s EXPORTED_FUNCTIONS='["_int_sqrt"]' -s EXPORTED_RUNTIME_METHODS='["ccall","cwrap"]' |
웹에서 받는 법이 두가지라는데 cwrap으로 하면 int_sqrt 객체를 만들어서 한다는데 리턴이 되는진 모르겠고
ccall로 하면 인자를 던지는게 조금 귀찮아 지지만 var result에 결과가 들어가는 듯.
int_sqrt = Module.cwrap('int_sqrt', 'number', ['number'])
int_sqrt(12)
int_sqrt(28)
// Call C from JavaScript
var result = Module.ccall('int_sqrt', // name of C function
'number', // return type
['number'], // argument types
[28]); // arguments
// result is 5[링크 : https://emscripten.org/docs/porting/connecting_cpp_and_javascript/Interacting-with-code.html]
