[BUG]ESP32-S3 block in InlineCurrentSense init

[mailonghua]

Describe the bug When using SimpleFOC, the program will stay at the current_sense.init(); function location

Describe the hardware setup For us it is very important to know what is the hardware setup you're using in order to be able to help more directly

• Which microcontroller ESP32S3FN8
• Current sensing used? INA240A2PWR IDE you are using
• Arduino IDE
• Platformio

Config file [env:esp32-s3-devkitc-1] platform = https://github.com/platformio/platform-espressif32.git board = esp32-s3-devkitc-1 framework = arduino monitor_speed = 115200 lib_deps = askuric/Simple FOC @ ^2.3.1 SPI Wire lib_archive = false

CurrentCode

include

define A0 8

define A1 9

// current sensor // shunt resistor value // gain value // pins phase A,B, (C optional) InlineCurrentSense current_sense = InlineCurrentSense(0.01f, 50.0f, 8, 9);

void setup() { Serial.begin(115200); Serial.println("Start init current sense"); // initialise the current sensing current_sense.init(); Serial.println("End init current sense");

// for SimpleFOCShield v2.01/v2.0.2 current_sense.gain_b *= -1;

Serial.println("Current sense ready."); }

void loop() {

PhaseCurrent_s currents = current_sense.getPhaseCurrents();
float current_magnitude = current_sense.getDCCurrent();

Serial.print(currents.a*1000); // milli Amps
Serial.print("\t");
Serial.print(currents.b*1000); // milli Amps
Serial.print("\t");
Serial.print(currents.c*1000); // milli Amps
Serial.print("\t");
Serial.println(current_magnitude*1000); // milli Amps

}

I think I have located this problem. This is a bug. Each ADC of esp32s3 has 10 channels 0~9, and the SENS_SAR_MEAS1_CTRL2_REG register shows the status of ADC1, and SENS_SAR_MEAS2_CTRL2_REG shows the status of ADC2. But when I use GPIO9, currently The judgment detects BIT16 of SENS_SAR_MEAS2_CTRL2_REG, which belongs to ADC2. When I change if(channel > 7) to if(channel > 9), my current program is normal. But I think this method may not be appropriate for ADC2
