RA2L1 How to Read Ambient Temperature or Chip Temperature?
Hi Nidhi, Thanks for reaching out to Volt.Tech Engineering Community. The user manual seems to be inaccurate when applying the word" ambient".

Hi Nidhi,
Thanks for reaching out to Volt.Tech Engineering Community.
The user manual seems to be inaccurate when applying the word” ambient”. Die (chip) temperature can be calculated, as it’s proportional to the measured voltage from the ADC in the example. I attach a design that converts the voltage output of the ADC to the die temperature.

I hope it helps.

What should be the Voltage Across VBAT and VBAT of M4Z32-BR00SH1 Battery?
Welcome, to the community! The voltage between both terminals should be nominally 2.8 V, below 2.0 V it should be considered discharged. The battery is based on lithium carbon monofluoride chemistry and isn't rechargeable. Does it answer your question? Regards Alex

ESP32-C3-MINI-1 Automatic Upload Mode?
Still, you would use exactly the same circuit but with IO0 replaced with IO0, If you were to use something like a CP2102 or other USB-serial chip. Still, you generally do not need the auto-reset circuit as that functionality is built-in If you are intending to use GPIO18/ 19 to program the ESP32C3 dRead more

Still, you generally do not need the auto-reset circuit as that functionality is built-in If you are intending to use GPIO18/ 19 to program the ESP32C3 directly. (But do note that you may want to have * some * way to manually put the C3 into download mode while developing if you do something that stops the internal USB-serial- JTAG from working, like accidentally configuring the USB pins as GPIOs).
See lessHow to use LED Control PWM in low speed mode?
Not sure if the driver does not support all 16 channels. they may just not be supporting the low- speed option of the low- speed channels. But anyway, if you want to poke at the registers yourself, the LED PWM controller is documented in the TRM. Do not forget to actually turn the peripheral on, andRead more

Are the L9963E and L9963 battery control and balancing chips compatible with LiFePO4 batteries?
Welcome, to the community! L9963 is formerly on NRND (Not Recommended for New Designs), new designs should use L9963E rather.LiFePO4 has a minimal discharge voltage of 2.0 V, a typical cell voltage of 3.2-3.3 V, and a maximum charge voltage of 3.60-3.65. L9963E covers a voltage range between 0.5-4.6Read more

L9963E covers a voltage range between 0.5-4.6 V per cell, which thus includes LiFePO4, but should also be designed for it by the software of the advanced- position controller.

ESP32- C3 Fixing the Device into Download Boot?
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 RSRead more
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.

In e2-studio 2022-07 binary files can now be downloaded as part of the debug configuration in the startup tab. For example, the highlighted line will load the raw binary file into the QSPI memory every time the program to be debugged is downloaded.

Hi, As the clock speed is allowed by FSP configuration, it should be safe for all the peripherals. For example, I've tested OSPI with a clock source from MOCO and set it at 8 MHz. Could you share what makes you suppose it isn't working correctly? Regards,

ESP32-S3 Current Consumption with Radio Disabled
Hi, You can find this information in the ESP32- S3 datasheet, Table 4- 9" Current Consumption in Modem- sleep Mode".( Modem- sleep mode is the mode where the radios( modems) are turned off. That is your case.) The numbers range from 13mA to 107mA, depending on the CPU frequence, which peripherals arRead more
Hi,
You can find this information in the ESP32- S3 datasheet, Table 4- 9″ Current Consumption in Modem- sleep Mode”.( Modem- sleep mode is the mode where the radios( modems) are turned off. That is your case.)
See lessThe numbers range from 13mA to 107mA, depending on the CPU frequence, which peripherals are enabled, and what the CPUs are doing. For example, if the CPU frequency is 80 MHz and both cores are running, the current consumption would be in the range of 33 to 47 mA.
Pairing a Bluetooth Classic 2.0 trackpad with the ESP32. Possible? Simple?
Try using a cell phone app like" Bluetooth Terminal HC- 05" If you can pair and receive data with this from the trackpad also you can do it with an ESP32. It's my goto App for looking at data streams from Bluetooth.
