R7FA2L1 UART Recieve Data?
Hi, Thanks for reaching out to Volt.Tech Engineering Community. The UART- related interrupts can be seen below and call the defined callback function if it's defined.

Hi,
Thanks for reaching out to Volt.Tech Engineering Community.
The UART- related interrupts can be seen below and call the defined callback function if it’s defined.
If you do not want a break in you can disable it by configuring SCR( Serial Control Register) properly. Else, you can close UART withR_SCI_UART_Close() when no physical connection is established between the pins and open it again when there’s a connection.
Let us know if you solved your issue.
Regards,
See lessESP32-C3-MINI-1-H4 RTC External Power and Chip Enable?
Neither. The ESP32-C3 needs to have all 3.3 V power pins powered at the same time, it's not possible to power the RTC domain independently. Disabling the chip using EN will shut down the wholeness of the chip, including the RTC. To make use of the RTC in low-power mode, you need to use software to pRead more

Disabling the chip using EN will shut down the wholeness of the chip, including the RTC. To make use of the RTC in low-power mode, you need to use software to put the chip into a deep sleep.
See lessAmbiguity in L78M12AB. It is Not Clear that this Part is Obsolete or Active.
As far as I remember, there were a lot of changes and extensions, also the root designation of the component was changed from L78MAB/ AC to L78M and delivery forms in tubes were removed so that a new datasheet including an updated product website became necessary in 2004. As can be seen on the newerRead more

As can be seen on the newer website, the requested L78M12ABDT- TR is still in full production.
See lessInternal Low-Side Switch in LED5000?
Yes, it works in synchronous mode. still, after the low-side FET has been switched off, there's always a specific dead time while the inductor still drives current. That current would flow through the body diode of the low-side FET, reducing effectiveness and increasing the radiated noise. This behaRead more
Yes, it works in synchronous mode.
still, after the low-side FET has been switched off, there’s always a specific dead time while the inductor still drives current. That current would flow through the body diode of the low-side FET, reducing effectiveness and increasing the radiated noise. This behavior can be improved by using a Schottky that takes over the current during the dead time.

The problem will be simpler if you can use a single camera above the shelf, and good contrast colors. also, you're just counting circular patches of not-shelf- color or bottle-cap- color. OpenCV might be oversupply for that, but probably has the exact law already written. Still, counting gets harderRead more

See lessStill, counting gets harder, If you must look edge- on the shelf. But just detecting something is on the shelf( not counting) might be as simple as painting the wall behind the shelf a contrasting color and counting patches of not- background- color with further than N pixels.
Good lighting will be important.
Wireless Remote Controls?
The keyfob transmitters and the handheld transmitters all have FCC and Industry Canada transmitter certifications. The 433 MHz versions have also been tested and found to conform to the ETSI RED directive.

It's possible, but you won't be suitable to use the Read and Write API as handed.

See lessConnecting ESP32 Cam to a Multimeter?
Sure. Take a USB lead, cut off the external isolation, find the red wire, cut it in two, and connect the multimeter in between. Make sure the internal resistance/ burden voltage of your multimeter isn't too high if the voltage drop of the multimeter is too high, your ESP32 may brown out. ( You can tRead more

( You can try switching to the 10A range when you suppose that happens.)
