Using SC16IS750 (I2C UART/GPIO) with ESP-01? Interrupts?
Posted: Tue Jan 17, 2017 2:22 pm
Does anyone know if it is possible (or recommended) to implement an interrupt handler for the ESP-01 to use ONE (and only one) I2C device, SC16IS750 (I2C Serial UART with GPIO) that can handle interrupts such as a rotary-encoder might generate if using the GPIO pins of the SC16IS750? Or is the ESP-01 fast enough that polling for the status of the SC16IS750' Line Status Register (LSR) frequently, the recommended implementation? (light WiFi and other serial operations)?
Which would be the best ESP-01 pins to use for SDA, SCL and IRQ? (if it is OK)
(programming env - Arduino IDE)
Thanks
