I'm trying to initialize an LCD module (ST7796U controller) on a STM32F103VET6 development board using SPI1, yet the souce code I got from the seller is using software-simulated SPI instead of hardware SPI (with SPI1_NSS enabled as output):   #define...

I am now designing a board for STM32F103VET6 and would like to use the FSMC to control the TFT LCD (320x480 resolution)May I ask if there are any notes or guides that mention the layout requirements? Such as what conductor impedance should the data l...

The MCU used is STM32F103VET6. I want to use TIM3_CH1 (generating a PWM signal of 10kHz, 30% duty cycle) as the master input of TIM4_CH1. The TIM3 acts as the prescalar of TIM4 and thus making TIM4 to ouput a PWM signal of 200Hz and 60% duty cycle. T...
