<![CDATA[TOF CAM Sensor]]>Hi all,

can M5Stack "talk" serially with this sensor?

datasheet say it needs a TTL UART interface:

Baud rate 10 Mbit/s 1 bit = 0.1 µs
Start bits 1 Bit low active
Data 8 Bit
Stop bits 1 Bit high active
Parity No
Voltage level LVTTL 3.3 V

happy new year!!!

Serial.begin(10000000);
//connect to proper TX<>RX pins of M5Stack

For proper debug you can connect sensor with any USB<>UART board and try to run it with any terminal software (I use TeraTerm)

If you want to debug derictly with M5Stack you will need Serial2 as your example shows, but keep in mind that if its a software serial, such high speed wont work properly most likely

Baud rate 10 Mbit/s 1 bit = 0.1 µs
Start bits 1 Bit low active
Data 8 Bit
Stop bits 1 Bit high active
Parity No
Voltage level LVTTL 3.3 V

can I try something like that?


#include <M5Stack.h>

#define RXD2 16
#define TXD2 17


void setup() {

  Serial.begin(115200);
  Serial2.begin(10000000, SERIAL_8N1, RXD2, TXD2); 
  Serial.println("Serial Txd is on pin: " + String(TX));
  Serial.println("Serial Rxd is on pin: " + String(RX));

}

void loop() { 
  while (Serial2.available()) {
    Serial.print(char(Serial2.read()));
  }
  }

Then use any com port software, teraterm or termite and try to "talk" with sensor

for the moment I need just to send/receive commands/response serially....

How can I set up a serial communication with this sensor?

tnks a lot

I mean, ESP32 which is M5stack based on can

However, it needs to be tried with UIFlow.

Can do with Arduino / Micropython most likely
