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...

like the following code: int ANDresult = i&j; The value of ANDresult is 0x20022002. In our assignment our professor asked us to write down the address of the variable ANDresult, I tried to add ANDresult as an expression in the Memory monitor but ...

According to AN4879, PA9 must be used as VBUS Sensing and must not be re-used for other purposes. However, according to CubeMX, PA9 refer to USART1_TX and USART1 is the only port that supports memory reprogramming (STM32F103VET6 Datasheet Section, 2....

There's three... AN2784 appeared twice. And none of them mentioned about the trace impedance.

OW1TY2 · 2024-04-15

Yes, but none of the 3 FSMC-related documents mentioned about the trace impedance.

So does it mean that to locate the address (not value) of a variable in Memory, I have to add a "&" before it?

OW1TY2 · 2024-02-15

Because the content of the memory address 0x20022002 are all "?", and I'm certain that 0x20022002 shall be the exact value stored in the variable ANDresult.Like this:

SPI for LCD failed to transmit data on STM32F103VET6

Are there any documentations about FSMC layout?

No output PWM for slave TIM channel

How can I locate the starting address of a variable in STM32CubeIDE?

Is STM32F103VET6 not supported to use USART1 and USB simutaneously in self-powered devices?
