Hi!It's a beginner question, but what is te purpose / use case the CCM RAM in STM32F4-series?I asking this due to CCM RAM in this MCUs connected to D-bus only. For this reason, this implementation don't have code execution capability nor DMA.I'm afra...
We are using the STM32H753ZI and to test if the LSE and HSE have the correct frequency, we want to measure it's frequency using TIM16 and TIM17.We managed to measure the frequency of the LSE using the internal input capture of TIM16 but when we tried...
I transplanted the general FFT algorithm ,but it took a lot of time for the CPU to run .I wonder if I can save time by using a Standard DSP library.
my init: I2C1->TIMINGR= 0xB0420F13; //p942 p917 XTAL=48MHZI2C1->MY_I2C->TIMEOUTR= 0x0000900A; //p943I2C1->CR1=1; no irq are involved (yet)then I'm trying to start a frame (slave not connected- still- I would like I2C to send 1st byte)I2C1->CR2=...
Hi folks,i'm using a STM32H750 MCU for analog data acquisition. I've implemented a simple UART Command interface to trigger a measurement with a given number of samples. This Interface works fine (checked it with the debugger).Now the Problem: only t...
Hi,We're currently using STM32F446ZE on a board but we'd like to switch to a dual bank flash device as to secure OTA update. Searching some sort of 'equivalent' (indeed, they're not pinout equivalent but, at least, use the same LQFP 144 package) we f...
Posted on March 01, 2018 at 14:28That is anoying. STM32CubeProgrammer does not work in DFU mode and Its probably a driver problem. On Page 7/39 in UM2237 STM32CubeProgrammer software description - DFU Driver. There it is described to uninstall the o...
Hi I'm new to STM32 and I am exploring this MCU. I have the STM32F103C8T6 MCU. I just want to ask some help how to enable PWM using interrupts. I am using TIM2 CH1 and set them on the CubeMX. Now I use PA6 as input switch to enable and disable th...
Hello,We noticed different behavior between J-Trace and I-Jet.We use both with IAR.It started on trying to trace code with stm32h743 eval board. we purchased j-trace for this issue, but it failed to trace code. Trying to do the same with I-Jet it suc...
Hello,I am using AT command for ESP8266. First, I am sending AT\r\n in main.c and receiving with interrupt Rx. After receiving first response, I am going on to transmit second AT command inside HAL_UART_RxCpltCallback. Everything was good with this m...
