Would be the part of the program code executed faster if its section was linked to be moved from flash to ram on startup? This code is executed many times.
Why I need to add delay after HAL_UART_Transmit_DMA and before memset at IRQ call back function
void vcom_IRQHandler(void) // external interrupt for USART2_IRQHandler { HAL_UART_IRQHandler(&UartHandle); USER_UART_IRQHandler(&UartHandle); } void USER_UART_IRQHandler(UART_HandleTypeDef *huart) { if(USART2 == ...
Resolved! STM32L552 - trying to set 3 GPIO Pins as inputs(w/ wo pull-downs) to be read before most initialization, but some pins on the board are always HIGH?
I'm trying to use 3 GPIO Pins as a 3-bit ID essentially. Depending on the values read, the uC will configure itself in an appropriate way (1 bin fits all tools essentially). The problem I'm having is that with the eval board the pins are pretty close...
How to clear the DMA functions` redundancy words?
when I use the DMA functions as below:HAL_UART_Transmit_DMA(&huart1,(uint8_t *)aTxStartMessage,sizeof(aTxStartMessage));HAL_Delay(10000);In PC side,It always display such symbols at the hand of the aTxStartMessage after the first success reciever. Wh...
VSSA VDDA and analog / digital ground separation. What's best?
Hello,I have a mixed signal application in development, a home energy monitor, and following on from the recent PCB version's test results on the effects of noise, and after reading this article, I've decided to separate my digital and analog ground,...
Resolved! STM32 PLL clock source doesn't work
Posted on June 18, 2017 at 09:21 Hello i have a program on the 32F030f4p6 chip for testing the system clock frequency. It blinks an LED at about 1Hz. the problem is that when i change the PLL multiplier from 2 to 12 the LED still blinks at the sa...

Resolved! Problem getting CLK and MOSI on SPI1 using STM32F091.
Hi there,Variations of this question have been asked before, but I have had no luck so far.I am attempting a very simple setup where I am using SPI to write to a display, where the screen does not talk back. I am using SPI1 on the STM32F091 and canno...
Resolved! Help me understand how to fix this issues with ADC scan feature
Hello,I'm using a STM32G431 MCU ADCs in dual mode. I'm trying to get control of the sampling rate and have found a frustrating issue. I don't need to scan multiple channels. Though the only way to get maximum sampling rate, or to have any control ove...
