Unable to set HIGH for any pins but GPIO2
Posted: Fri Apr 01, 2016 7:54 amHi guys!
I'm having a problem with my ESP8266-07. Everything works fine (WiFi, button interrupt etc), but I just can't blink more than 1 LED. Here's my code:
All I get here is one LED connected to GPIO2 blinking, but not one connected to GPIO4.
I tried other GPIO pins with no luck - only GPIO2 HIGH output works.
Any ideas what am I doing wrong?
Thanks in advance!

I'm having a problem with my ESP8266-07. Everything works fine (WiFi, button interrupt etc), but I just can't blink more than 1 LED. Here's my code:
Code: Select all
void uset_init(void) {
// ...
PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO0_U, FUNC_GPIO0);
PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO2_U, FUNC_GPIO2);
PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO4_U, FUNC_GPIO4);
// ...
// Timer initialization
// ...
}
void set_lights(bool enabled) {
if (enabled) {
gpio_output_set(BIT2, BIT4, BIT2 | BIT4, 0);
} else {
gpio_output_set(BIT4, BIT2, BIT2 | BIT4, 0);
}
}
All I get here is one LED connected to GPIO2 blinking, but not one connected to GPIO4.
