Where does my const array go? (memory type?)
So, if we have a large amount of hard coded data we want to incorporate into my program, my presumption was that a const array would allow the compiler to treat the data more like code, than data, in terms of cost against your CPU limits.This was alm...
Power pins of STM32F103RDT6
Hi,I am using STM32F103RDT6. Kindly suggest me LDO for convert 5 to 3.3V and details regarding decaps values for the all supply line of STM32.
Sampling rate calculation of STM32F7 ADC with GPIO Toggling
Hi,I use internal ADC of the STM32F767 microprocessor. I set the ADC parameters like this,static void MX_ADC2_Init(void) { /* USER CODE BEGIN ADC2_Init 0 */ /* USER CODE END ADC2_Init 0 */ ADC_ChannelConfTypeDef sConfig = {0}; /* USER...
Why do I miss a missing sample from time to time?
Hello,I need to sample 2 signals simultaneously at a rate close to 1MSPS on 16 bits.On a Nucleo-H743ZI2 board, I thus configured ADC 1 and 2 in Dual regular simultaneous mode, 1.5 Cycle between sampling phases, only one single conversion on each ADC....
How to send data from cloud to STM32L475 device?
I'm using STM32L475 board. I'm able to send data from the device to the cloud (IBM Watson), but I do not know how to send some message from the cloud to the board (e.g. to change the state of a led). Do you know an easy way to do it?
Resolved! Flashing software via ST-LInk
Dear all ,I know that this is the ridiculous questions with engineers here, but i still have to ask because i really don't know. Pease forgive for me if this type of questions were already answered in another topic.I'm using STM32F100 to design the ...
Resolved! DMA transfer complete but interrupt never fires
STM32H745I'm performing a DMA transfer, the TCIF gets correctly set, but the interrupt never fires. I've ensured the TCIE flag is enabled and interrupts are enabled. What am I missing? What else should I be checking?Attached is a picture from debuggi...
Resolved! What is the lowest power mode for STM32L053C6 that keeps the status of the GP outputs?
Sorry for the dumb question, but I am rather new to this family of products.I need to have two different possibility to exit a LP mode in different phases: in one case I can wake-up via the internal comparator, and this can be done even in STOP mode,...
Purpose of series resistor in TSC
Hi,I'm wondering what the purpose of the series resistor (Rs) is for touchkey applications. I have found in documentation and presentations that it is for extra ESD immunity, but can someone be more precise? Thanks,CT
