Hello,

I am in the process of learning my way around microcontrollers and designing an IOT device that will include a thumb keyboard. The font used will be an older one used on BBS systems and I envision holding control keys to utilize the upper area of the fonts for drawing.
As similar, I am aware that the esp32 lacks the pins demanded to program a keyboard so I am thinking a keyboard controller chip would be needed. Does anyone have a recommendation on what I should use?

I looked up many but they feel to be more fit for a laptop and apparently preprogrammed.

Thanks & Regards

Hii,  I’m designing a dev board based on ESP32- C3 (ESP32- C3FN4) and I’m not sure if I’m good with connections for download boot.
Is it enough to put tactile switched on GPIO2 and GPIO8 towards VCC and pull down on GPIO9?

Also, should I include a connector in case the device needs to be flashed?

    Hello, You need to start your esp32 with the Low position on the Boot pin to begin the bootloader. In normal mode, u can hold a HIGH position on this pin by pullup him up with 10k, for example. Generally, you can use 2 buttons for switching modes, 1- to connect the boot pin to GND, 2- to pull the RST( EN) pin to GND- for resuming esp32 (you need to pull up it too). Also, you can use special schemes which will do it automatically.

We want to develop a USB- C charger and we need to check the battery charge percentage of the device connected to the USB- C charger. The connected to de USB- C device can be a Smartphone, Tablet, or PC.

In our charger, we’re going to integrate a processor and we need to read the battery percentage of the device that’s being charged

Is it possible to read the battery percentage of the device connected by USB- C? Any ST reference can do this job?

    Battery_status message can give the SOC of the sink.
    The info will be available only on the PD3 sink( designed with version> = PD3.0 v1.2).

    PD2 devices do not have similar communication.
    That information is handled in the dpm_user part and needs to be updated by the user/ customer.

What I see is that the eval board output the power thru the terminal block, I’m curious how it’ll auto-select the voltage demanded. that’s no additional signal or feedback connected to the eval board.

The first device can auto-select to output five 5V also follow Bluetooth speaker devices, it auto-generates 15V. Let’s say I want to connect to an Uno board. which is DC 7- 15V, how will the eval output be?

    EVAL- SCS001V1 is grounded on the STUSB4500, which can store three PDO profiles( power data objects) in its NVM and informs the connected power force( source) of the voltage and current to be supplied.

    Since the EVAL- SCS001V1 has no information about the needed voltages and currents of the connected loads( sinks,e.g. your UNO), these values have to be stored in the NVM of the included STUSB4500. Programming can be done. g. with the GUI STSW- STUSB002.
    As soon as the EVAL- SCS001V1 with your UNO board is connected to the USB- C power force, the set power can be requested.

    The PI7C7300D is” hot- exchange friendly”, which basically means it can affiliate to a hot- exchange power regulator. But by itself can not withstand Vcc = 0V and live signals at the I/ O pins– in this mode, current will flow through our ground. Thus, if ever there’s a possibility of this passing, we require a hot- exchange power regulator and switches for isolation. However, also the less expensive or PI3C32X245 switches are applicable for the signal switches. Most of our guests use this switch in their operations.
