STM32 IoT Node BSP in low power mode

Hi Community,I am working on developing applications using STM32L4 IoT discovery kit. So far i am able to configure sensors and read data from it. Connect to WiFi and transmit data via mqtt are working fine so far. I am also interesting in implementi...

STM32F107 SPI receiving problem

Hello,Here is my SPI configuration and interrupt codes:void SPIConfiguration(void){ SPI_InitTypeDef SPI_InitStructure; GPIO_InitTypeDef GPIO_InitStructure; NVIC_InitTypeDef NVIC_InitStructure; RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB,ENAB...

DMA-> GPIO STM32f103

Hello,I need to transfer 42 pulses (with 1 pin of a port) and read incoming bits from 1 pin of a port( such as SPI communication). As this forum member trained me I am curious to use DMA to generate 42 pulses with sending a specific value(10101...). ...

STM32F769 EVAL DMA for TIM2 PWM occurs only once, why?

I am trying to set-up a PWM with 20kHz pattern and every time the PWM is over to add a new one. I am using to start-up the DMA if (HAL_TIM_PWM_Start_DMA(&TimHandle, TIM_CHANNEL_3, SamplingPoints, length) != HAL_OK) functionFirst time the pulse is sen...

ADC and DMA timing calculation

Hello,I am trying to figure out how long an ADC in dual mode and DMA will run to take 24000 samples. I cannot get any proper values. My init at startup:bitset(SCB->ConfigCtrl, bit9); // set STKALIGN in NVIC bitset(SCB->AIRCR, (0x5FA<<16)|(...

STM32F103C8Tx ADC count

Hello for my project I need 10 diffrent ADC's. I am planning to use STM32F103C8Tx for this project. In the dahasheet of it, "There are 2 ADC's with 16 external channels are available" information was given. So what I want to know is that, what is the...

UART RX FIFO not working

I can’t seem to get the FIFO to work on the RX side. TX works fine.Seems as if the FIFO isn't used. If I interrupt on the "RX not empty" event and read the data, it works fine. But as soon as I want to interrupt on any FIFO event, I never get the int...

Newbie here.... I need to take a fast ramp to a bluetooth controlled temperature measurement and a PID temperature controller.....

can somebody give me a point to an eval board set that I could use with perhaps STMCube toolset?Thanks so much for your kind help and for the kickstart.

Hi, I am using stm32f103zet6 board for development purpose. I want to implement CAN protocol. Which transceiver is suitable for CAN implementation?

Data Collision between USART and SPI.

I my project I use UART 1 and 2 and SPI 1 and 2.When I send data via UART 1 using the function "HAL_UART_Transmit_IT (....)" and the second line in code I use the function "HAL_SPI_Transmit (....)" the data received from the UART 1 is incorrect, th...
