I tried to run pico w iperf server example, in the example there are some pending functions say "press 'd' to disconnect", but when I press keys on keyboard, only PICO_ERROR_TIMEOUT is returned by getchar_timeout_us(0).
Here is an simple code I copied from iperf example:
char key = '!';
void key_pressed_worker_func(async_context_t* context, async_when_pending_worker_t* worker){
printf("%d is pressed\n", key);
cyw43_arch_disable_sta_mode();
}
static async_when_pending_worker_t key_pressed_worker = {
.do_work = key_pressed_worker_func
};
void key_pressed_func(void* param){
key = getchar_timeout_us(0);
printf("key is pressed");
// if(key == 'd' || key == 'D'){
async_context_set_work_pending((async_context_t*)param, &key_pressed_worker);
// }
}
int main(){
stdio_init_all();
if(cyw43_arch_init()){
printf("failed to initialise\n");
return 1;
}
async_context_add_when_pending_worker(cyw43_arch_async_context(), &key_pressed_worker);
stdio_set_chars_available_callback(key_pressed_func, cyw43_arch_async_context());
//something else after this line
The printf() in key_pressed_func() is never been called and the printf() in key_press_worker_func() gives "-1 is pressed" (-1 means timeout from getchar_timeout_us(0)).
here is the output from minimum:
