Good afternoon,I am testing my UART and using a vector to store float numbers as shown below: raptor::std::vector<float> numbers; numbers.append(3.14f); numbers.append(2.21f); numbers.append(1.01f); numbers.append(8.15f); numbers.append(0.05f);H...
Dear Sirs,Is there a method to calculate the firmware size?I am using STM32F103R8T6My flash memory is divided in three blocks:- Custom boot loader block- Main application block- Data blockWhen the main application is running, it needs to calculate it...
I'm using Keil uVision 5 and ST-Link debugger (Mini). I have a very curios issue with STM32F746, running at 50 MHz.On the board I'm communicating with a display via FMC. "Suddenly" (as in, I don't know what I changed) the program did not work anymore...
I'm using the STM32H735 to create a sequence of PWM signals. I have timers TIM1, TIM2, TIM4, and TIM24 all connected in a slave timer chain. TIM1 triggers TIM2 with ITR0. TIM2 triggers TIM4 with ITR1, and TIM4 triggers TIM24 with ITR3. Each link in t...
Hi,1. Can the selected input channels to ADC0, ADC1 and ADC2 in STM32H753ZI be sampled simultaneously under the same sampling clock?2. NUCLEO-H753ZI ADC does not accept the analog negative signal inputs. Is there any STM32H7 dev board(s) accepting th...
I'm tring to work with a STM32F030F4. Unfortunately I didn't manage to flash the application on the controller. I'm using openOCD with a ST-Link.I use the following to start openOCD: openocd.exe -f interface\stlink-v2.cfg -f target\stm32f0x.cfgI now ...
Hi, My test board can enter sleep mode OK, but doesn't wake up when PC13 goes high: (never reach __enable_irq()) void Sleep() { __disable_irq(); SysTick->CTRL = 0; // Enable WKUP4 (PC13) PWR->WKUPEPR = PWR_WKUPEPR_WKUPEN4; // Enable WKUP4 PWR->WKU...
Hi,i was trying to change dead time from (244 value to 100) for every 10ms in a loop. But its not updating , the set dead time is 244 in the PWM waveform. Though my dead band register ( DTG) is updating at every 10ms. I am updating TIM1->DTR2 if(en...
Good morning. I'm running an STM32F767Zi on a custom board, LwIP 2.1.2, no OS. The device acts as a HTTP server. I've got an issue where I get GET requests and [FIN, ACK] packets retransmitted by the web browser.192.168.5.106 - Client192.168.5.196 - ...
