riscv/bl602: Implement SPI Cmd/Data by lupyuen · Pull Request #5898 · apache/nuttx

lupyuen · 2022-03-29T02:22:10Z

Summary

To control the Data/Command Pin on ST7789 SPI Display, the SPI Driver flips the MISO Pin as though it was a GPIO.

To implement this on BL602, we reconfigure MISO from SPI Pin to GPIO Pin on the fly inside bl602_spi_cmddata().

When the SPI Port is deselected (after the SPI operation), we revert MISO back from GPIO Pin to SPI Pin. We implement this inside bl602_spi_select().

More Details Here

Impact

This change impacts 3 LCD drivers that call SPI_CMDDATA(): ST7735, ST7789, GC9A01.

Previously the BL602 SPI Driver would fail with "SPI cmddata not supported" when the above drivers are used.

After the change, the above drivers will set the LCD Data/Command Pin correctly.

Testing

We tested this implementation of SPI Cmd/Data with NuttX ST7789 Driver and a Logic Analyser on PineCone BL602:

Testing with Logic Analyser

We also tested LVGL with ST7789 on PineCone BL602:

Testing with LVGL

As for regular SPI Devices that don't require SPI Cmd/Data, we tested CONFIG_SPI_CMDDATA=y with Semtech SX1262 SPI Transceiver on PineCone BL602:

In function "wm8904_hw_reset" the priv->balance is initialized with b16HALF, indicating a range from 0 to b16ONE. In function "wm8904_setvolume" the assumed range for priv->balance is between 0 and 1000. The changes now make this consistent for 0 to b16ONE-1. Furthermore, in wm8904_configure the change of balance was not implemented. Minor fix, function name was wm8994_setvolume instead of wm8904_setvolume. Fixed source code format errors.

The current implementation of env_dup does precisely this and thus, it fails at once when it is attempted between two user processes. The solution is to use the kernel's heap as an intermediate buffer. This is a simple, effective and common way to do a fork(). Obviously this is not needed for kernel processes. syscall: Add call gate for get_environ_ptr Now that the environment strings are stored as an array of strings, they can be passed from the application via char **environ, which is really defined as a function call to get_environ_ptr(). This works as is for flat build, but protected mode and kernel mode require a call gate, which is added here. binfmt_execmodule: If incoming envp is NULL get parent envp This keeps backwards compatibility with apps that do not provide envp. The old implementation passes NULL always and this change fixes any regression caused by it. assert: static_assert is not support in c standard C89,C99.
