Can not able to transmit continuously
Hi,i am transmit data through can protocol in stm32f103 controller in the while loop and i am doing doing adc and display data on 16x2 lcd so i found that doing this my can transmit is transmitting only 4-5 times amd then stop so i want to ask what c...
Resolved! Hi, My signal is 50Hz and 175Hz (about 20% of 50Hz), Sampling 25600 samples/Sec. Implemented with 4096 pointFFT. I am getting 50Hz spectrum @8th location and expecting 175Hz at 28th location. but it is distributed to 24 & 30. other spectrum shows zero
Can any one help me on this. thanks in advance
Timer in Encoder Mode Interrupt via Output Compare
I know, I'm repeating an age old question, but has there been any updates on generating an Interrupt when using a Timer in Encoder mode? I know, that the Interrupt doesn't fire in Encoder mode, but I read in this one thread, that it's somehow possibl...
Ordered MCUs have shorted pins
Hello. I recently purchased STM32F405RGT6's. However, out of package and on all of the IC's that I received, I discovered shorts between pins 17 (PA3) and 18 (VSS), which I do not believe should be shorted. I have a few STM32F405RGT6's that I purchas...
[SOLVED] --- Encoder very easy code ---
Here the code to read encoder.unsigned int Enc_dir; unsigned int save_a = 0, save_b = 0; void BSP_Encoder_Init() { GPIO_InitTypeDef gpio_init_structure; __HAL_RCC_GPIOF_CLK_ENABLE(); gpio_init_structure.Pin = GPIO_PIN_8; gpio_in...
STM32F746 Flash Memory Organization?
The datasheet for the STM32F746VET shows that it has 512k bytes of Flash. But the Reference Manual for the STM32F74xxx shows 1Mbyte of Flash (sectors 0 thru 7). Do we just assume that sectors 6 and 7 don't exist? This seems a bit vague.
Resolved! STM32L476 SPI NSS bit not functioning
Using an stm32l476rg nucleo as a master device and SPI2 peripheral. The following bits have been set in order for the NSS bit to stay high normally and then be pulled down during communication (according to the reference manual).MSTR = 1SSM = 0SSOE =...

How to Configure the Timer etc to specific need for GPS aligned ADC sampling
Dear ST team,I tried to use CubeX, did not able configured as needed. I done separate two timers, the results are not accurate and lots of jitter without any other application.Need - Using GPS receiver's PPS output to aligned the sampling of external...
