Hi, guys.
I want your recommendation for AWS IoT Provisioning.
I am looking for wifi and ble of EPS Module to connect to AWS IoT Core.
I mean this module has wifi and ble.
I need it to be ready to use AT Command by the host MCU.
I hope your answer.
Thank You

Hi all,
I am testing to configure node 2 and node 3 on module CAN1 to be linked to the inside can bus and out.
My final aim is to transfer some data on cun node 1- 2 and receive it on can nodes 1- 3 without any processing in the CPU.
no purifier configuration and messages to be transferred, no pack/ unpack function- just as simple as that loop back out.
so I set all needed configurations where I had the node working on normal mode( transfer and receive messages, filter, and messages defined), but also I removed the configurations of the filter and added to the configuration the needed flag
rc = canNodeConfig (& nodeConfig, reeCanNode);// set common configurations * nodeSfr = IfxCan_getNodePointer (nodeConfig.can,nodeConfig.nodeId); nodeSfr->NPCR.B.LOUT = 1;
for both nodes 1- 2 and 1- 3.
what eventually happens is that I send from an outside source and it looks like the CPU receives (no errors on the bus) but the other bus has errors on it.
how can I be sure that the messages entered into that node? will interrupt for TX/RX receive?
what should I do to test it correctly?
is the setup OK for my purpose? (loop back out)?
Thank You

Hello, Connected to the internal CAN bus and loop back the messages received on node 2 to node 3 without any further processing by the CPU.

Hello,
Connected to the internal CAN bus and loop back the messages received on node 2 to node 3 without any further processing by the CPU.
To accomplish this, you can configure both nodes to operate in normal mode and enable loopback mode for node 2 using the LBP bit in the NPCR register. The LBP bit sets the loopback mode for the node, allowing it to receive its own transmitted messages.
Here are the steps you can follow:
You can also use interrupts to receive messages on the nodes. You can enable interrupts for receive and transmit events and write interrupt service routines (ISRs) to handle the events. When a message is received, the corresponding receive interrupt will be triggered, and the data can be read from the received message object.
Kind Regards,

Hey, I am creating a smash barrier controller with ESP32 SX1276 LoRa microcontroller, and I require a 5V external power force, but I can not find anywhere which pin of 5V is the VIN one, I do not want to ruin my module, so does anyone know this particular module and which of the 5V pins is the VIN one? I have uploaded the board setup for reference purposes. If you want any extra information please let me know.
Thank You

Hello, They are likely both connected to the Vin signal; check with a multimeter if there is continuance between the two pins if you want to make sure. Thank You Nidhi Singh

Hii, From boost converter (u really do not need it but anyway.) to ESP32- wroom 5v pin (from photo bottom left pin) and from charge- to GND (ANY OF THEM).
Can connect a USB to the ESP32 WROOM directly (with this connection in place, no need to disconnect) and flash any firmware you want, also disconnect the USB, and if the battery is full and it’ll work.
Can also connect a USB to the TP4056 for charging WHILE it feeds the ESP32.
You really do not need the Boost since the TP4056 will output3.7 v and you have a 1000mah (milli amps hour) battery which will allow the ESP32 to work for a good while (depending on what u are doing etc) before recharging. In this configuration just connect the OUT to3.3 v (top left) and OUT- to any GND pin.
But u will need a USB connection to load any firmware and later disconnect it and let the battery feed the ESP32.
Enjoy.

Hello, I notice the supply for the RTC is also connected to the general 3V3 supply on the schematic for the ESP32- C3-MINI-1-H4 module.
If I supply3.3 V power to the ESP32- C3-MINI-1-H4 but have the enable line low, so chip impaired, will the RTC keep on running if it has been set before?
Or for the RTC to remain running but the chip powered down will I need to produce my own layout to break out the RTC 3V3 pin and thus I won’t be suitable to use the ESP32- C3-MINI-1-H4 module?
Thanks

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

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.)

How we’re implemented SPI poling in ESP32- S2- WROOM module. But now I need to apply SPI DMA for Transmit and admit.
is ESP32- S2- WROOM module supports SPI DMA?
actually we searched in github, I find SPI DMA stack but in that no DMA related functions.
Given that you're using the ESP-IDF SPI driver and assign a DMA channel to the host driver when initializing it, you're already using DMA. The driver will use DMA for data transfers automatically.

Hi,
First check whether the SPI communication is successful, the successful sign is that the version value of the read chip is 0x12, the DIO0 pin is responsible for notifying the MCU that the reception is completed and check whether the DIO0 pin configuration is normal. The configuration parameters of LoRa should be consistent, including frequency, spreading factor, bandwidth, coding rate, preamble length, frequency hopping enable, syncword, and low-rate optimization; if one of the above parameters is different, communication cannot be performed.
