    The ESP-IDF codebase plus toolchain are available in ARM Linux flavour, so you could possibly try installing them in a chroot on the tablet. You can install Arduino as an ESP-IDF subcomponent as well if you want to use that API.

Hi, I’m presently using an STP16CPC26, and due to a supply shortage, we’d like to replace it. The STP16CPC05 seems a good fit, but I can not really find the differences with the PC26, except for the current output( 90mA ...Read more

    Welcome, to the community! Yes, the newer STP16CPC05 can replace the older STP16CPC26 and contains some advancements that make component selection easier (smaller bypass capacitor possible) or the slightly advanced maximum driver current. Does it answer your question? Regards

How to do Input Voltage Compensation in DOB for Single Channel?

input voltage compensationvoltage compensation
  1. Sandeep kumar

    Hi Janam, For this please find the formula, and with help to below formula we can calculate the Rvd Resistance for input voltage compensation V ref =0.6V-0.15x{(105K/105K +RVD) VD-1.2V} Thanks

    Hi Nidhi,

    Thanks for reaching out to Volt.Tech Engineering Community.

    If I understand right you need to program the data flash of the device just right?
    The data flash can be written in both ways, by Renesas Flash Programmer, or by self-programming (by the software running on the device).

    To program only the data flash with Renesas Flash Programmer, the file used to program the device would require to hold only data for the data flash address range. A. srec,. hex, or. bin file can be used with RFP to give the data to be programmed into the flash.

    Regards

    Ashish

    It’s not required per se, but it’s helpful. The issue is that an empty ESP32-C3 usually will try to boot from flash and fail. After some attempts, the RTC watchdog will protest in to reset the entire chip. This is useful as it may clear any transient error that would stop a properly flashed chip from booting. However, it also resets the USB-serial- JTAG device, causing the OS tore-enumerate it. Going into download mode (either by pulling low GPIO9 or by successfully connecting using the flashing app) stops that from passing, allowing the chip to be flashed as normal.

    Not having GPIO9 accessible will generally work (depending on how fast your OS is in detecting USB devices) but may need several tries in flashing for the timing to be right.

    Another thing is that without forcing the chip into download mode, for old performances of the esp tool, a watchdog will keep running during the flashing process, which may interrupt flashing if the firmware is fairly large. Using a newer version of the esp tool should fix that, however.)
