Problem with buffer_size_send parameter using multiple SPI block

Hi everyone, I'm having problems using several SPI blocks for different data length transmission via SPI with a STM32F303 MCU. I've realized that when I try to send multiple messages with different data length (using different SPI blocks) the data bu...

How to check the working condition of the CAN Transceiver?

Recently I bought a CAN Transceiver(SN65HVD230 CAN Board Network Transceiver Evaluation Development Module) to convert CAN_RX, CAN_RX signals into CAN_H, CAN_L from a STM32L476RG Nucleo board. How can I check this Transceiver, whether it is working o...

How to connect STM32F469 discovery kit to Silabs thunderboard 2 through USB ?

Hello, We're trying to connect an STM32F469 discovery kit and a Silabs thunderboard 2 through USB, in order to send data between the ST kit and a BLE device using Thunderboard 2.There are two accessible UARTs on STM32F469 dev kit, UART3 which is also...

I have to Initialize and Use the Timers in Existing Demo Code in STMcubeIDE .Can any one tell me how to configure in STMcubeIDE on Existing code ??

STM32F103C8 internal Temp sensor on which channel? ADCx_IN16 or ADC1_IN18

Hireading the ref manual of the STM32F103C8, it says in chapter 11.10 that the temp sensor is internally connected to ADCx_IN16. In figure 39, it says that the temp sensor is connected to ADC1_IN18.I reckon that this is a simple typo, or do I miss an...

STM32L452 DMA + SDIO Overrun Issue

Hi Guys,I'm currently using an STM32L452 device and i'm having some problems with the SDIO when using it with DMA.I have configured DMA and SDIO usign the file generated from STM32Cube tool.When I try to read the SD card without using DMA , everythin...

Once the DAC DMA is started, do I need to stop it in order to change the content of the buffer? Or I can simply do a HAL_DAC_Start_DMA() again with an updated buffer?

Is there a way to trigger an interrupt that fires a different method from a UART IRQ?

I got some excellent advice on a previous question and have a new related question. I have a app that needs to run a control loop at a specific rate with something like a few percent jitter. For example, if the control loop is supposed to run every...
