Thank you for your quick response and my apologies for answering you at these times due to work. Answering to @MarkT and @KurtE, the link you sent me (
http://www.lcdwiki.com/2.8inch_SPI_M...41_SKU:MSP2807), is that i am using for references, notice in that link the photo of the board show the following description: "2.8 TFT SPI 240X320 V1.1", and the board i am working is "2.8 TFT SPI 240X320 V1.2", I don't know if the version change has to do with any difference. Just as a reference, look at the following link because this is the correct board i am using (V1.2):

I continue answering (@FrankB):
Librarie: ILI9341_t3
Teensyduino: 1.53
Arduino: 1.8.13
Pin connections:
ILI9341 Teensy 4.1
VCC VIN
GND GND
CS Pin 10 (CS)
RESET Pin with 3.3V (in the middle of Pin GND and PIN 23)
D/C Pin 9 (PWM/OUT1C)
SDI (MOSI) Pin 11 (MOSI)
SCK Pin 13 SCK (pin in the middle of pin 14 and GND), this is the pin of LED.
LED (BL) VIN (connected using a 100 ohm resistor). This VIN-Pin is the same i use to connect MSP2807 VCC.
SDO (MISO) Pin 12 (MISO)
Next CODE is an example of library ILI9341_t3 under name "graphicstest"; i change the serial.begin command to 115200 (original was 9600 - baud_rate)and I also played around for a moment specifying the other pins and changing the frequency in tft.Clock and checking this with an oscilloscope on pin 13. This showed me some inconsistent flickering on the screen.:
