Re: ESP32-S3 RGB LCD maximum throughput

My fork of the CircuitPython code that uses this is located here:
https://github.com/kmatch98/circuitpyth ... ockdisplay


can this(https://github.com/kmatch98/circuitpyth ... ockdisplay) CircuitPython support RGB TFT LCD?

Re: ESP32-S3 RGB565 and octal SPI for video use

so cool! I actually managed to connect NT35510 TFT 800x480 to K210 with octa SPI multi-line setup Haven’t tried OTM display yet - they look the same https://www.youtube.com/watch?v=QieHNK1mC5c It is interesting I was able to transfer images thru UART at 2000000 baud rate I am trying now to add touch...

Re: ESP32-S3FH4R2封装问题

应该也能直接焊接上去吧?

晶振问题

ESP32-S3 硬件设计指南 V1.1中第12页中说“尽管 ESP32-S3内部带有自校准功能,但是晶振本身的质量问题,比如自身频偏过大(例如大于 ±10 ppm),工作温度范围内稳定度不高等晶振本身的质量问题仍然会影响芯片的正常工作,导致射频指标性能下降”,选取晶振的时候是不是需要考虑全文度范围内频偏小于 ±10 ppm?

Re: ESP32-S3能否支持这些

我也是新手,一起探讨。我一直印象WIFI和蓝牙不能同时用吧?所以感觉ESP32-S3上,摄像头,WIFI或(蓝牙键鼠,蓝牙耳机对话),SD卡,USBOTG,一路串口通讯 感觉应该是可以的,不行就再加IO扩展吧

请问ESP32-S3上,摄像头,WIFI,蓝牙键鼠,蓝牙耳机对话,SD卡,USBOTG,一路串口通讯可以同时使用吗,最好再留5个IO输出。
