eadf / esp8266_easygpio Goto Github PK

This is not an issue but I haven't found a way to send you a PM.

I wanted to let you know that I've started to port my hardware abstraction tool to the ESP. It is called HWA and you'll find it here on Github (https://github.com/duparq/hwa). I am just at the beginning with ESP but a few Atmel AVRs are almost fully implemented and there are examples to show how easy it makes things. Comments and suggestions welcome.

Regards.

I'm adapting to run in noduino -sdk version. My problem is not having the libeasygpio.a . Where can I download or generate .

I don't know if this will solve the bug you describe in the comment (haven't tried it) but it looks like there might be a typo in the implementation of easygpio_inputGet on line 301: https://github.com/eadf/esp8266_easygpio/blob/master/easygpio.c#L301

// this does *not* work, maybe GPIO_IN_ADDRESS is the wrong address
return ((GPIO_REG_READ(GPIO_IN_ADDRESS) > gpio_pin)  & 1UL);

Shouldn't that > be a >> instead?

How do I add a interrupt to GPIO 0

This seems not to work. Not sure if I need easygpio_pinMode before easygpio_attachInterrupt? I thought I might have forgotten some init function or similar, but I can not find any reference to it. What is wrong?

#include "osapi.h"
#include "easygpio.h"

int interruptOne = 42;

static void sonoffBtnInterrupt(void* arg) {
  uint8_t value = easygpio_inputGet(13);
  easygpio_outputSet(13, !value);
}

void ICACHE_FLASH_ATTR user_init() {
  easygpio_pinMode(13, EASYGPIO_PULLUP, EASYGPIO_OUTPUT);
  easygpio_outputSet(13, 0); // turn on

  //easygpio_pinMode(0, EASYGPIO_PULLUP, EASYGPIO_INPUT);
  bool success = easygpio_attachInterrupt(0, EASYGPIO_PULLUP, sonoffBtnInterrupt, &interruptOne);
  os_printf("easygpio_attachInterrupt success: %d\r\n", success);
}

Thanks in advance!

I might be wrong but I THINK that open-drain settings are missing here. I note in the i2c example - they set the outputs as open drain like this..

//Set SCK as open drain
GPIO_REG_WRITE(
    GPIO_PIN_ADDR(GPIO_ID_PIN(I2C_SCK_PIN)), 
    GPIO_REG_READ(GPIO_PIN_ADDR(GPIO_ID_PIN(I2C_SCK_PIN))) | 
    GPIO_PIN_PAD_DRIVER_SET(GPIO_PAD_DRIVER_ENABLE)
);

What is the real license of this code? In the root directory it is GPL but in your individual c files it appears to be BSD 3-clause license

The title says it all. Any plans to fix it?

How many GPIOs can I use with the ESP-07 or ESP-12? (not including ADC)
GPIO 15 is tied to ground and GPIO 0 is... well I hope that I can leave it.
Thanks

maybe I`m dumb but how can I set a gpio high?
I use this to specify which gpio pin i want and that the pin should be an output:

uint8_t gpio_pin = 0;
EasyGPIO_PinMode pinMode = EASYGPIO_OUTPUT;

But how can i set the level of the gpio to high or low now?
