Hello @SB12345

ok, have you tried to only connect one TOF4m to port C? Does that work?

Thanks
Felix

@drdrewusaf @TiukuP @falbriard @gbelfor @heyheyyt @Rango @RBOUMAN58
already fixed, thanks for patience

@cepics The files are there, they are only edited and compiled with PlatformIO.cpp files:
https://github.com/m5stack/Atom-JoyStick/tree/main/examples/StampFlyController
Here is the main:
https://github.com/m5stack/Atom-JoyStick/blob/main/examples/StampFlyController/src/main.cpp

Hello @ScheduleDisplay

I am glad to hear it works for you now.

Yes, the battery will drain much faster when using ESP32 deep sleep or light sleep compared to a full shutdown.

You can find the currents for all three modes here.

Thanks
Felix

I think the MODULE_4_20MA (in the src folder) is only using some standard libraries:
From top src/MODULE_4_20MA.h:

#ifndef __MODULE_4_20MA_H #define __MODULE_4_20MA_H #include "Arduino.h" #include "Wire.h"

Try to download only the two files in the src-folder and see if you can include them into your project and compile.

Also: If you look at the code in src/MODULE_4_20MA.cpp you'll see that they include some register addresses, maybe that is required for this AIN4-20mA unit?

@flypeek this code, Atom g21 and g25 connected to the scroll grove port and library original pin assigment, works!!!

#include <M5Atom.h> #include <M5UnitScroll.h> M5UnitScroll unitScroll; void setup() { M5.begin(); Serial.begin(115200); if (!unitScroll.begin()) { // if (!unitScroll.begin(&Wire, 0x40, 26, 32, 400000U)) { // if (!unitScroll.begin(&Wire, 0x40, 32, 26, 400000U)) { Serial.println("Errore nell'inizializzazione del sensore"); while (1); // Ferma il programma in caso di errore } // LED unitScroll.setLEDColor(0x0000FF); } void loop() { int32_t encoderValue = unitScroll.getEncoderValue(); Serial.print("Valore encoder: "); Serial.println(encoderValue); if (unitScroll.getButtonStatus()) { Serial.println("Pulsante premuto!"); unitScroll.setLEDColor(0xFF0000); // Rosso delay(500); unitScroll.setLEDColor(0x00FF00); // Verde delay(500); } delay(100); }

but I need to connect the unit to the Atom grove port.... some tips??

Using the LoRa868 (old version) w/ Core Basic works as expected w/ precompiled meshtastic firmware. Thanks to @felmue for his hints.

If you want to use precompiled firmware then look into variants.h for the used GPIO and check your Core and LoRa Module whether the IO fits or not.

@felmue Hi, felix i got it working finally. The issue is, on platformIO the library Arduinomodbus library and ArduinoRS485 library are the arduino ones and not the m5stack ones which is why i was getting error.
A fix to this was to just replace the internal files of library to the m5stack ones from github.
Thank you for the help.

@sternj Well, the Arduino IDE ver2 IDE is very good.
Just type in C, C++ and download (it compiles automatically.)
This is NOT your grandad's Arduino IDE ver 1 !!!
Here is a sample program to test serial:

bool ticktock; //declare ticktock as a boolean flag void setup() { //runs once on start up Serial.begin(115200); //open the serial port for USB cable delay(500); } void loop() { //runs in circles! ticktock = !ticktock; //every pass through reverse the flag if (ticktock) { //test current value of the ticktock flag Serial.println("tick"); } else { //prints one or the other to the USB port Serial.println("tock"); } delay(1000); //wait for a second and run again! }

Исправлено, спасибо за терпение.

SOLVED : After remeniscing abount my life, and specifically what goes wrong here, i just realised : could it be that I am using an outdated library of ClosedCube. And yes, after using the version from 4 April 2023, everything works fine now.

@felmue In Dutch : Krijg nou wat?
I put the RFID 2 module in slot 1 of the TCA 9548A module and then in channel 0 (weird because i have placed it in channel 1) i see address 0x28 of the RFID popping up.

Does this mean that channel 0 on the module is not usable?
Thanks

In follow_up , I have checked ClosedCube_TCA9548A.cpp and the selctChannel goes like this :

uint8_t ClosedCube::Wired::TCA9548A::selectChannel(uint8_t channel) { uint8_t result = 0xff; if (channel < TCA9548A_MAX_CHANNELS) { Wire.beginTransmission(_address); Wire.write(((uint8_t)1) << (channel)); _currentChannel = channel; result = Wire.endTransmission(); } return result; }

That seems to be correct if I read the documentation of the Texas Instrument module TCA9548A

I am really misunderstaning something or could it be that their is somekind of wire mixup in the module?

Btw, I also dont see a reset channel somewhere in the code.

Now i did another experiment using PCA9548AP (the newer version).
Plugging in the RFID in channel 0 gives no response.
Plugging in channel 1 : software tels me the device is in channel 0
Plugging in a second RFID in channel 2 :software tells met a I have another device in channel 1.

I tried to increase the max number of channels to 8 (assuming that channel 0 is somehow connected to channel 7 of 8). Still no response when i attach a device physically on channel 0.

This is really weird behaviour. I hope someone is at least able to reproduce this behaviour.

@ajb2k3 When you have a moment, I would really appreciate your thoughts or any updates you might have.

@Krmiller
Maybe you should look at the source code of the library to see what it does directly when connecting to the first/second client...I think it's still related to the blockage

@nishad2m8 Nice work and well done writing it up.
Thank you.

@felmue Thank you for the pointer! Looks like perhaps it's fixed for the Arduino implementation? It does not seem fixed for the ESP-IDF version quite yet. Your workaround combined with the pre_cb and post_cb callbacks worked! Here's a snippet/summary of what I did:

#ifdef CONFIG_M5CORES3_SPI_CONFLICT_FIX #define M5CORES3_SPI_CONFIG_FIX_MISO_PIN 35 void sx127x_spi_pre_transfer_m5cores3_fix_callback(spi_transaction_t* t) { // before a SPI transaction is started, we need to change the driving direction // of the DC pin in the CoreS3 (the CoreS3 uses the MISO pin as the DC pin and // configures it as an output ping which conflicts with other SPI devices on the bus) // set gpio direction for MISO pin to input gpio_set_direction(M5CORES3_SPI_CONFIG_FIX_MISO_PIN, GPIO_MODE_INPUT); } void sx127x_spi_post_transfer_m5cores3_fix_callback(spi_transaction_t* t) { // undo pin direction change after SPI transaction is done // set gpio direction for MISO pin back to output gpio_set_direction(M5CORES3_SPI_CONFIG_FIX_MISO_PIN, GPIO_MODE_OUTPUT); } #endif sx127x_handle_t sx127x_init(const sx127x_modem_config_t* modem_config) { // ... // Configure SPI device spi_device_interface_config_t spi_dev_cfg = { .clock_speed_hz = 9000000, // 9MHz .mode = 0, .spics_io_num = modem_config->cs_gpio, .queue_size = 7, .flags = 0, #ifdef CONFIG_M5CORES3_SPI_CONFLICT_FIX .pre_cb = sx127x_spi_pre_transfer_m5cores3_fix_callback, .post_cb = sx127x_spi_post_transfer_m5cores3_fix_callback #endif }; ret = spi_bus_add_device(spi_host, &spi_dev_cfg, &device->spi); if (ret != ESP_OK) { ESP_LOGE(TAG, "Failed to add SPI device"); vSemaphoreDelete(device->spi_mutex); free(device); return NULL; } // ... }

I can now use both the display and the sx1276 at the same time on the M5Stack CoreS3.

Thanks again for your assistance!

@kuriko
Indeed a strange situation.
It occurs if I use TX=26 and RX=32 and also TX=22 and RX=19 to initiate the can BUS on a M5Atom
ESP32Can.CANInit(); // Init CAN Module. 初始化Can

If i dont initiate WifI I can send data through the CAN BUS. The moment I initiate WiFi, no data come through in the CAN BUS.

I will do some other trials with other devices (M5Core 2 and M5Atom S3) to check if it is a hardware problem.

I do hope to get this solved because if this problem is definite it means the Communication abilites of the CAN bus are limited.
Regards

(* Oh, important : When using WiFi i do receive CAN BUS messages , so that is weird, i really need to dive into this*)

@aitech doesn’t work but I have replaced the second boot screen, yes there are 2 boot screens. The primary boot screen is controlled by the DTB file and need recompiling, the second is in another location.
The guide will be in my CoreMP135 Update document closer to Christmas from the FB groupe

@colythdev Fair enough. M5Stack has a Visual Block IDE that creates Python scripts. Called UIFlow.

I personally use Arduino IDE to create C, C++ source files, automatically compiled into Op Codes and downloaded to the M5Stack device.

Both styles are supported by M5Stack.

The examples I linked to you are Arduino IDE.

Have fun and learn!

@kuriko @BizyBee is trying to load hacker software to interfere with RF communications, onto a Cardputer. Which is illegal and immoral.
