ST7789
According to the datasheet, what is the maximum speed of the ST7789 for the SPI protocol? If we use an LCD with the ST7789 driver and connect it via the SPI protocol to a microcontroller, would we get higher speed with the STM32G0B0CET6 microcontroll...
Resolved! allocation of global variable SD-RAM external memory.
The 'HAL_SDRAM_Write_8b' and 'HAL_SDRAM_Read_8b' functions were confirmed using STM32H723ZGT6 and IS42S16320D-6TLI.(Check variable value changes with STM32CubeIDE's Memory Viewer and LiveWatch, no hardware problems)All internal RAM has been used to i...
Resolved! BOOT0 pin and BOOT bits
I am using an STM32 G474RE NUCLEO board. Is it necessary for me to configure the BOOT0 pin and the BOOT bits in the FLASH_OPTR register if I am going to program the chip using the SWDIO and SWCLK pins with an ST-LINK V2?

Resolved! stm32f429 tim8 in up count mode, update interrupt couldn't generate 10Mhz PWM.
stm32f429 ran in PCLK2 with 160MHz, and TIM8 prescaler division set to 0, auto reload set to 1.set up interrupt enable.in TIM8 update interrupt handler, just toggle PD4 pin out.when use oscilloscope to check the wave of PD4, just get around 2.3MHz. C...
