W806 Lianshengde 9.9 yuan development board experience 4 --- SDK surprise discovery [Copy link]

 

Because the SPI polling transmission was too slow last night, I was thinking about looking at the registers and configuring DMA transmission. I didn't expect to see that the official SDK actually provided TFT LCD examples with 8080 interface and SPI DMA interface. It's great. No need to reinvent the wheel.

That's good, but the official should provide some TFT LCD examples with 8080 interface and SPI DMA interface,,,

Keep reinventing the wheel.

After reading the W800 register manual, the following DMAs are supported: uart, pwm, spi, adc, i2s, SDIO

There is no I2C

I don't know if I understood it wrong.
