Hi Satoshi, it is not possible to reset only MMPF0100 I2C module, you can just initiate new power up sequence to reset whole MMPF0100. In general if
This project using framework esp-idf on module esp32-wroom. We use a separate task to render screen, that means this task's only purpose is to call function "spi_device_transmit"(defined in "spi_master.h") in its loopWe now have a problem on SPI display, the function "spi_device_...
I was able to find whenever failure condition happened, the data line is low, and "busy" flag is set in the i2c status register. (See the attachment for detail). I am always able to reset the MCU to clear the issue, which means the data line is not holding by any I2C slave. I ...
Connect Grove - OLED Display 0.96" with I2C as well as PWR and GND. Connect serial port of SAMD21 with serial port of Intel CPU. Step 5: Install front and rear lids and tighten the screws. Heat removal Cold wind provided by the fan flows through CPU cooling fins and SSD, thus removi...

and then you can use the pins or bus like: [output_pin caselight] pin: host:P20 [temperature_sensor enclosure_temp] sensor_type: HTU21D i2c_mcu: host i2c_bus: i2c.1 htu21d_hold_master: False Author eziologico commented May 26, 2020 Hi @dianlight , Thank you for your reply. ...
I2C bus works according to a certain protocol. Next, let’s take a look at the I2C protocol. I2C supports multiple slaves, that is, multiple I2C slave devices can be attached to one I2C controller. These different I2C slave devices have different device addresses so that the I2C master ...
However, if the redriver testing procedure involves a live PCIe link, then it is important to perform a warm reset of the link before evaluating the signal quality through lane margining and similar tests. Both the PCIe transmitter sending signals to the redriver, and the PCIe receiver that ...
