Resolved! unexpected output
Below is my code:uint8_t line[50]="Application is Running\n";uint8_t Buf[50];uint8_t A=0,B=0; while(! HAL_GPIO_ReadPin(GPIOC, GPIO_PIN_13)); // wait for user button press HAL_Delay(200); strcpy((char*)Buf," \n\nI am in the Loop \n"); HAL_UART_Tra...
Signal integrity problems with STM32L476 FSMC interface causing emission
FMC is configured to interface asynchronous sram (IS61WV25616, 10ns). FMC 16-bit databus is multiplexed between sram and LCD controller.Data transfer happens using DMA. MCU system clock is 80Mhz. Supply voltage is 3.3VSram and LCD controller is worki...
Resolved! How to syncronize timers?
Hi I'm using STM32F407 development board. I want to syncronize TIM2 and TIM5. I've followed these instructions. Here is my TIM2 initialization function below:void TIM2Config (void) { /*************>>>>>>> STEPS FOLLOWED <<<<<<<<************ 1. Enab...
STM32H745 VDDSMPS Default Configuration?
Hello, I have 2 clarification questions on the default VDDSMPS configuration for the STM32H745:I notice multiple times in the STM32H745xI/G datasheet that "VDDSMPS must be kept the same voltage level as VDD." Similarly, RM0399 also has a note that VD...
Resolved! HSLV example code?
I am using a U585QI and have some external flash memory connected to an OCTOSPI. We are having some intermittent failures with it, and since we're powering the processor with 1.8v I want to try enabling HSLV for the Data/Clock lines. I found HAL_GP...
HAL_UART_Receive_IT skips bytes from RN2483 lorawan module
Hi,I want to use a lorawan device with my stm32 l053r8 microcontroller.To do this, i reset the lora module initially. In Response I should get the firmware version of the device, but i receive only parts of the string, e.g. some bytes between the st...
How to send TSC data from STM32L476 rg into a file on a computer along with time stamp
I'm trying to use the TSC on the STM32L476rg board. I've been able to view the value on the watch window on Keil and using stmstudio. Now how do I store the values obtained into a text file on my computer along with the timestamp of each reading?
Resolved! I'm trying to use the I2C multiplexer TCA9548A and I can't seem to get any output from the output ports.
I'm using the Nucleo32L031 board connected to a Adafruit TCA9548A 1:8 multiplexer board. I have the board setup properly, Vcc = 3.3, GND, SCA and SCL pins double checked. I have a Sparkfun TMP102 temp sensor board connected to the TCA9548A's port0.I ...
