Hello and Happy New Year 2022,I'm using STM32L072, I set SPI1 to be in "Transmit Only Master" mode, and DMA1 as SPI1_TX (DMA1 Channel 3)I use CubeMX to Auto generate my codeThe relevant SPI1+DMA1 line is: HAL_SPI_Transmit_DMA(&hspi1, (uint8_t *)aBuff...

Hello,I'm using STM32WB55 in conjunction with freeRTOS OSI found a very good I2C BARE-METAL working example located at:..\STM32Cube\Repository\STM32Cube_FW_WB_V1.12.1\Projects\P-NUCLEO-WB55.Nucleo\Examples\I2C\I2C_TwoBoards_AdvComITI'm looking for a ...

In my project I uses 2 LEDs and one Buzzer, all of them based on PWM controlMy current HW implementation is as follow:Led#1 connected to PA.3 - PWM based on TIM2/CH4Led#2 connected to PB.9 - PWM based on TIM1/CH3NBuzzer connected to PA.0 - PWM based ...

Hello,I have a project which contains both: Bootloader (BL) and Application (App.)The BL is based on minimal devices without interrupts, mainly RS485 - and worked Fine!The App. is based on "BLE_PERIPHERAL_LITE" example by ST, with my additional freeR...

Hi MDas3,In general I, on I2C Master side which is based on freeRTOS and also based on ST example named: I2C_TwoBoards_AdvComIT, I created two I2C functions (I2C_master_write_to_slave() and I2C_master_read_from_slave()) then able to call them whene...

Hi Vincent,I don't have this issue anymore, I changed a bit the order and add some small delaysI'll Not be able to comment in the coming month (overseas vacation)Make sure you use HAL_Delay(xx); at this stage and NOT osDelay(xx) in case of freeRTOS u...

Hi KnafB,Thanks you very much for your GREAT advise :smiling_face_with_smiling_eyes: !!!The original I2C example is based on HAL functions: HAL_I2C_Master_Transmit_IT() and HAL_I2C_Master_Receive_ITI added freeRTOS with CMSIS_V2 (from CubeMX) + one I...

Hi KnarfB,Thanks for your replyWill create an I2C Task then try to perform HAL_I2C_*** procedure Best Regards,Micha

DMA1 CCR register is NOT updated (NOT Written)

I2C implementation based on freeRTOS OS

What is the best way to debug I2C on 2 Nucleo Platforms (one Nucleo is Master the other Nucleo is Slave) while using ST CubeIDE?

Is it possible to use multi GPIOs based on one common PWM channel?

STM32WB, what might cause CPU2 to FAIL and stuck during initialization?
