Maybe you can help me as well. I am trying to get an Adafruit ESP32 S3 TFT board to work with FreeRTOS. I load the Adafruit Feather S3 TFT BSP.
It compiles OK, no errors, but when loading it into the board, I get a hardware crash, and a bootloader display on the LCD screen. The code is listed below.
// define two tasks for Blink & AnalogRead
void TaskBlink( void *pvParameters );
void TaskAnalogRead( void *pvParameters );
// the setup function runs once when you press reset or power the board
void setup() {
// initialize serial communication at 9600 bits per second:
//Serial.begin(9600);
//while (!Serial) {
// ; // wait for serial port to connect. Needed for native USB, on LEONARDO, MICRO, YUN, and other 32u4 based boards.
//}
// Now set up two tasks to run independently.
xTaskCreate(
TaskBlink
, "Blink" // A name just for humans
, 128 // This stack size can be checked & adjusted by reading the Stack Highwater
, NULL
, 2 // Priority, with 3 (configMAX_PRIORITIES - 1) being the highest, and 0 being the lowest.
, NULL );
xTaskCreate(
TaskAnalogRead
, "AnalogRead"
, 128 // Stack size
, NULL
, 1 // Priority
, NULL );
// Now the task scheduler, which takes over control of scheduling individual tasks, is automatically started.
}
void loop()
{
// Empty. Things are done in Tasks.
}
/*--------------------------------------------------*/
/*---------------------- Tasks ---------------------*/
/*--------------------------------------------------*/
void TaskBlink(void *pvParameters) // This is a task.
{
(void) pvParameters;
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, LEONARDO, MEGA, and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN takes care
of use the correct LED pin whatever is the board used.
The MICRO does not have a LED_BUILTIN available. For the MICRO board please substitute
the LED_BUILTIN definition with either LED_BUILTIN_RX or LED_BUILTIN_TX.
e.g. pinMode(LED_BUILTIN_RX, OUTPUT); etc.
If you want to know what pin the on-board LED is connected to on your Arduino model, check
the Technical Specs of your board at https://www.arduino.cc/en/Main/Products
This example code is in the public domain.

AnalogReadSerial
Reads an analog input on pin 0, prints the result to the serial monitor.
Graphical representation is available using serial plotter (Tools > Serial Plotter menu)
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

for (;;)
{
// read the input on analog pin 0:
int sensorValue = analogRead(A1);
// print out the value you read:
//Serial.println(sensorValue);
vTaskDelay(1); // one tick delay (15ms) in between reads for stability
}
}
Other software on the module works OK, including all the tried examples, as well as the sample TFT routines.
Any ideas what to try to resolve this?
