RE: Unit Cam greyed out on UiFlow -- Core2 and StickC Plus
@creakygate same here, also greyed for atoms. No solution that I know.

atom matrix, wrong number of leds.
With this code:
#include <M5Atom.h> void setup(){ M5.begin(true, false, true); //Initialize M5Atom. delay(50); //Delayed 50ms. M5.dis.fillpix(0xFFFFFF); delay(10000); M5.dis.clear(); } void loop(){ }
I've got 24 leds on, the last one off , but if I change the
#define NUM_LEDS 25 to 26 in
.pio/libdeps/m5stack-atom/M5Atom/src/utility/LED_DisPlay.h
I've got 25 leds on
Is it a known bug in the atom lib? -

RE: Using atom-mate with cback-driver.
@felmue thanks, now it compiles and uploads to the atom. But it does not work. I have also changed the ports in CBACK_DRIVER.cpp to match the ones of the atom-mate, from
Wire.begin(0, 26);
to
Wire.begin(19,22);
but no luck.

Using atom-mate with cback-driver.
I¡m trying to run a couple of servos with atom lite, using the atom-mate and the cback-driver for m5stick. Using platformio, I've copied CBACK_DRIVER.h and CBACK_DRIVER.cpp to the include dir in the project, modified the obvious #include <M5Atom.h>, and with this code:
#include <M5Atom.h> #include "CBACK_DRIVER.h" bool flag = true; CBACK_DRIVER Driver; int C_BLACK = 0x000000; int C_WHITE = 0xffffff; int C_RED = 0xff0000; int C_GREEN = 0x00ff00; int C_BLUE = 0x0000ff; void setup() { M5.begin(true, false, true); // let's check the atom is ok delay(50); M5.dis.drawpix(0, C_GREEN); // green delay(1000); M5.dis.drawpix(0, C_BLACK); // black Serial.begin(115200); Driver.Init(); delay(1000); Serial.println("C Back Driver Test..."); } void loop() { if(M5.Btn.wasPressed()){ flag = !flag; Serial.println("toggle flag value"); } if(flag){ for(int i=1; i<=4;i++){ Driver.SetServoAngle(i,90); Serial.println("servo 90"); // Driver.ReadServoPulse(i,1500); } Driver.SetOutput(1); }else{ for(int i=1; i<=4;i++){ Driver.SetServoAngle(i,120); Serial.println("servo 120"); // Driver.ReadServoPulse(i,2000); } Driver.SetOutput(0); } Serial.print("PortB ADC: "); Serial.println(Driver.ReadADC()); M5.update(); }
I get this error:

@felmue Thank you very much for the solution and the explanation. It now works,

StickC reboots when sending message via esp-now. [solved]
As the subject says, I have copied the example code for esp-now on esp32 from randomnerdtutorials to comunicate a stickC with an Atom Lite. If the atom is off,the code works ok, but if the atom is on, the message is sent once, and then, the stickC reboots, in a loop, send message, reboot, send message, reboot.
/* * based on https://randomnerdtutorials.com/esp-now-esp32-arduino-ide/ */ #include <M5StickC.h> #include <WiFi.h> #include <esp_now.h> // wifi settings const char* ssid = "cositas_electronicas"; IPAddress local_IP(192, 168, 0, 101); IPAddress gateway(192, 168, 0, 1); IPAddress subnet(255, 255, 0, 0); IPAddress primaryDNS(1, 1, 1, 1); //optional IPAddress secondaryDNS(9, 9, 9, 9); //optional // esp now // receiver mac address uint8_t broadcastAddress[] = {0x24, 0xA1, 0x60, 0x46, 0xF1, 0x70}; // structure to send data, must match receiver structure typedef struct struct_message { char a[32]; int b; } struct_message; // create a struct_message called myData struct_message myData; // callback when data is sent void OnDataSent(const uint8_t *mac_addr, esp_now_send_status_t status) { M5.Lcd.fillScreen(BLACK); M5.Lcd.setCursor(0, 20); M5.Lcd.println("Last Pkg send status"); M5.Lcd.println(status == ESP_NOW_SEND_SUCCESS ? "Delivery Success" : "Delivery Fail"); } void setup() { M5.begin(); Serial.begin(115200); Serial.println("starting...."); WiFi.mode(WIFI_AP_STA); // Configures static IP address if (!WiFi.config(local_IP, gateway, subnet, primaryDNS, secondaryDNS)) { Serial.println("STA Failed to configure"); } // Connect to Wi-Fi network with SSID M5.Lcd.fillScreen(BLACK); M5.Lcd.setTextColor(GREEN , BLACK); M5.Lcd.setRotation(3); M5.Lcd.setCursor(0, 20); M5.Lcd.println("Connecting to "); M5.Lcd.println(ssid); WiFi.begin(ssid); while (WiFi.status() != WL_CONNECTED) { delay(500); M5.Lcd.print("."); } // Print local IP address M5.Lcd.fillScreen(BLACK); M5.Lcd.setCursor(0, 20); M5.Lcd.println("WiFi connected."); M5.Lcd.println("IP address: "); M5.Lcd.println(WiFi.localIP()); delay(1000); M5.Lcd.fillScreen(BLACK); Serial.println(WiFi.macAddress()); // init esp-now if (esp_now_init() != ESP_OK) { Serial.println("Error initializing ESP-NOW"); return; } // Once ESPNow is successfully Init, we will register for Send CB to // get the status of Trasnmitted packet esp_now_register_send_cb(OnDataSent); // Register peer esp_now_peer_info_t peerInfo; memcpy(peerInfo.peer_addr, broadcastAddress, 6); peerInfo.channel = 0; peerInfo.encrypt = false; // Add peer if (esp_now_add_peer(&peerInfo) != ESP_OK) { M5.Lcd.fillScreen(BLACK); M5.Lcd.setCursor(0, 20); M5.Lcd.println("Failed to add peer"); return; } } void loop() { // Set values to send strcpy(myData.a, "This is a char"); myData.b = random(1, 10); // Send message via ESP-NOW esp_err_t result = esp_now_send(broadcastAddress, (uint8_t *) &myData, sizeof(myData)); if (result == ESP_OK) { M5.Lcd.fillScreen(BLACK); M5.Lcd.setCursor(0, 20); M5.Lcd.println("Sent with success"); } else { M5.Lcd.fillScreen(BLACK); M5.Lcd.setCursor(0, 20); M5.Lcd.println("Error sending the data"); } delay(2000); }
In the serial monitor I get this:

This happens in two different stickC, using platformio in linux. Any ideas?
