Re: Connect ESP32-S3 to the graphics chip BT815Q via SPI
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: https://github.com/MatrixOrbital/EVE3...

Re: Connect ESP32-S3 to the graphics chip BT815Q via SPI
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 discard...

Re: Connect ESP32-S3 to the graphics chip BT815Q via SPI
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 this on...

Connect ESP32-S3 to the graphics chip BT815Q via SPI
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://g...
