Posted on July 04, 2017 at 14:59hi,i work on WIFI module SPWF04SA and SMT32F401RE with STM32CubeExpansion_WIFI_V3.0.2 (app client_Socket + MDK-ARM V5.22.0.0).i would like to migrate to STM32F401RB on my board but i have some issues! Pb1: i migrated ...
Posted on July 25, 2017 at 12:25Hi,HAL_SPI_TransmitReceive(SPI_HandleTypeDef *hspi, uint8_t *pTxData, uint8_t *pRxData, uint16_t Size, uint32_t Timeout) In this API Size is in Byte or in Bits?Thank you.
Posted on August 01, 2017 at 02:32Hello,In the AN4550 , chapter 5.1.1 SDADC from HW design describe SDADC gain.I confuse about difference between analog gain(0.5 2 4 8) and digital gain(16 32).Is the Analog gain change the gain using MUX?Is the Dig...
Posted on July 29, 2017 at 00:27I am having trouble changing any DAC registers using the STLINK debugger. The processor is stopped and the DAC is configured via Cube to be DAC Out 1 with output buffer enabled and no triggering. I let the code run th...

Posted on July 30, 2017 at 10:48Hi,I set two F303VC Discovery boards with the same configuration using cubeMx: they have same clock on apb2 bus and time segment 1 and 2 and RJW are both the same.One is programmed as a receiver and the other as a tra...
Posted on July 31, 2017 at 16:09 I'm using the PWM function of TIM4, on an STM32F429, to control an RC servo. This requires a pulse between 0.6 and 2.4 msec, at a rate of about 50Hz. Everything works fine, if I don't need to change the pulse durat...
Posted on July 31, 2017 at 13:56I made a mistake when designing a PCB for an STM32L152RE (the 64 pin variant) - I had thought the VDDA pin was the voltage reference for the ADC, so I wired this to an accurate 3V reference supply. My main supply is 3...
Posted on July 28, 2017 at 14:40It appears from the (rather lacking) documentation that the DMA Double Buffer Mode is only a Peripheral to Memory transaction. Is this correct? Or can I use double buffering from memory to peripheral?
