i am trying to use I2C port as GPIO. two port use as input mode button(low active). so i configured register. I2CCFG = 0; // disable i2c I2CWC = 0x80 // GPIO function.

The CH341 is declined in several flavors, and may support one or more of UART, SPI, I2C and GPIO, but not always simultaneously: - CH341 A/B/F: UART, Printer, SPI, I2C and GPIO - CH341 C/T: UART and ...

gpio read now works fine (with really good usb cable ... (see kitchen sink repo for working usbadc) I had to patch i2c-tiny-usb to keep it from attaching to interface 2, ill include the patch in ...

We’ve gotten used to the GPIO-available functions of Raspberry Pi ... the Raspberry Pi 4 has six SPI controllers, six I2C controllers, and six UARTs – all on its 40-pin header.

The MCP23017, a 16-bit I2C GPIO expander, has always been a tasty chip. With 16 GPIOs addressable over I2C, proper push/pull outputs, software-enabled pull-ups, eight addresses, maskable ...

Microcontrollers from the MAXQ family are well-suited for such bit-banging applications because of their high-speed, flexible GPIO modules and separate I/O ... out one of the two statements that ...

I've been working on LaunchPad F28377S for a while now. I recently got an OLED I2C display to work with. In TMS320F28377S technical reference guide, they mentioned GPIOs 42,43 and GPIOs 91,92 both for ...

Drive blue LEDs with a reduced supply voltage by using a few I/O lines from an I²C GPIO expander IC (MAX7315). Blue LEDs are becoming prevalent in the industry, and sometimes make their way onto ...

The GPIO cell set can be configured as input ... Digital cells for 25MHz, 75MHz, and 150MHz allow optimization across SSO currents & power. A 3.3V I2C open-drain (fail-safe) and a 3.3V analog cell ...

This flip-chip compatible library in Dongbu HiTek 130nm features a fail-safe GPIO, two standard GPIOs, a 5V GPI, and 5V I2C-compliant ODIO. The GFGPIO is a highly configurable 5V tolerant, ...

Turnkey touch controllers are an easy way to upgrade from mechanical buttons to modern touch buttons or displays. With the release of its 12-button MTCH2120 touch controller, Microchip Technology ...
