Hey guys, I have the problem that the BT815 has stopped "talking" to me.

If I want to query the ChipID after restarting the system, there is no longer an answer on the MISO line.

Previously I connected an Arduino Mega to the monitor using this library:

Hey,

Thank you, Raquel, for your response.

I've since resolved my issues and made significant revisions to the code provided.

My assumption that I could read the Chip ID was incorrect. The BT815Q writes some data to the MISO line during the write process from the master, and this data can be ...

I have another question related to the topic:

I couldn't find any information in the datasheet about how to interpret the data from the MISO line.

I'm sending the following command to the chip:

wr32(REG_FREQUENCY + RAM_REG, 0x3938700, spi); // Configure the system clock to 60MHz

When I check ...

Hey,
Thanks for the quick reply.

I would like to operate the following display:

Hello there,

I'd like to connect the ESP32-S3 to the BT815Q graphics chip from Bridgetek.

For this, I'm following the instructions in the manual: https://brtchip.com/wp-content/uploads/2022/12/BRT_AN_033_BT81X-Series-Programming-Guide.pdf

I'm also referring to the code example for Arduino: https ...
